Laggy performance during high usage - caused by System Interrupts

Q: Laggy performance during high usage - caused by System Interrupts

After I returned from Holidays...I noticed that when I perform tasks that use considerable amount of CPU, the computer 'lags' and the sound seems to freeze. Each cycle being 1 sec long. It will continue to do so until I leave the computer and close CPU-consuming applications such as games, Media Players etc...It usually happens when I play games and watch movies though...

I initially thought that it was a virus so I scanned etc, then I thought it might be due to the CPU overheating, so I opened my machine and checked the CPU paste. It was fine no problems there. Then I checked the processes, nothing and finally arrived at System Resources where I saw that 'System Interrupts' was eating around 30 - 50% of my CPU. I have searched google and haven't come to a solution for this. I have updated my chipset drivers, graphic card drivers, sound drivers, Network card drivers, Motherboard etc. There is no effect whatsoever. It's really frustrating me as I can't even listen to music sometimes...I had used up all of my USB ports, so I tried taking some out, but there was no result...

When I restart it kind of calms down, but then it comes again. Even when I type in my password to enter Windows, the welcome sound freezes momentarily again. I have recently bought this system (custom built myself) so I'm really frustrated and cant think of a reason why this happens so suddenly

Any help will be greatly appreciated

A: Laggy performance during high usage - caused by System Interrupts

Welcome to SF, msjamalan!

If it's a virus or malware problem, please reboot into safe mode and run your scans. Malwarebytes should be your malware scanner.

If you have a lot of applications open at one time, you may want to bump up your memory.

You can also run msconfig and see if you can uncheck startup items. Be careful with this one.

Still, I wonder why this change has occurred after you have returned from vacation. Can you think of anything different before and after holidays?

I have read couple of threads about this System Interrupts thing and none of them really helped me. I think you can check the specs somewhere, I am not sure since I am new to the forum.

Basically when I start my laptop everything is good for a while when suddenly the CPU usage goes high because of System Interrupts (~25%) and System (~12%). I have tried using LatencyMon to track down the problem and it used to give me alerting messages but now it gives me messages that are all green and nice ("Your system appears to be handling(...)").

Can you guys help me figure out this thing please? Thanks in advance.

NOTE: My drivers ARE up-to-date, but I am not sure my BIOS is. I don't really know how to update the BIOS though, it's a really weird model I have here, that has become obsolete.

*update1* Upon thinking that it might be the wireless driver or the network driver I disabled both, but it didn't drop the CPU usage
*update2*Now I get disconnected from the internet randomly... it may be the wi-fi driver after all

A:High CPU usage caused by System Interrupts and System

____________________________________________________________________________________________________ _____
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup.

So recently I have been ecountering an Issue with my pc where it becomes unresponsive usually while playing games that require network access.The CPU will spike to 95-100% for about 2-5 seconds and then shoot back down to normal percentages with a bout a 20 second window of usability before it spikes again. Even when I kill the games via task manager the cpu usage continues to spike intermittently.  I at least able to run process explorer and the high usage pointed to system interrupts and DFCS. The one catch is that the issue isn't persistent and when it happens it usually gets worse as time goes on making analysis via process explorer hard.
Any ideas of what could be causing this issue or information I could provide to help out?

Hi, usually my laptop had in fully idle state about 1-2% CPU usage. Currently I get approximately 8-10% CPU usage in idle state. From task manager, the most demanding process is System Interrputs consuming between 5-6% CPU.
I suppose this is abnormal high. Can I somehow lower this usage?
Because with 10% CPU the fan is already noisy even if I nothing is performed, annoying.

A:System Interrupts abnormal high CPU usage

If you are familiar with process explorer tools, you can pinpoint what process is causing the high load. I solved it by installing the newest graphics driver. But it may be any other driver in your system.

I just installed Windows 7. The CPU usage since I have started running it is staying at 100% constantly. When I go into resource manager it says that the process "system interrupts" with description " deferred procedure calls and interrupt service routines" is taking up an average CPU of 90. I have read that this may be a driver issue or that it may be a conflict between onboard graphics and a graphics card. I have both onboard and a card. I think I disable the onboard through BIOS when I installed the card. Do I need to do this again. The windows automatic update said it successfully installed the video card driver. Not sure about any other drivers. Here are my specs (except that I have added 1gb of RAM for a total of 2gb and installed a ATI Radeon Saphire HD 3650 graphics card). http://h10025.www1.hp.com/ewfrf/wc/documen...035&lang=en Thanks in advance for your help

Hi there, I've seen some posts about this, but nothing helped me.
I'm really asking for help here as my last resort.
I got an Asus laptop K53SC, intel core i7-2670QM with nvidia 520MX.
Problem is System Interrupts starts randomly eating up 1 core to 100%.
I've tried everything, I've contacted Asus support, but their technical level is below 0 (I'm surprised they haven't told me to buy another laptop).
All my drivers are from asus website, windows 7 is 64 bits Dream Spark edition.
Interrupts really start randomly and whenever they want (usually if I play a movie / play games / because of flash player etc...). The thing is sometimes they start after 5 min of movie play, others they did not start after 3 hours of movie play, which is making things harder. You got the ideea.

Technical informations. Ofcourse I've installed latency monitor / windows xperf.
Found out that acpi.sys / ntoskrnl.exe / hall.dll / I don't remember last 1, are causing highest DPC / Interrupts. The amazing thing is that only 1 is triggered at a time. Once is acpi.sys, once is hall.dll, once is tcpip.sys and so on.

I would appreciate really any real help that I might get here, because these interrupts drive me crazy. I've tried all versions of bios, I've tried to dissable audio HD, I've tried almost everything I saw on the internet but with no success. I don't even know what's causing it, I've heard it may be the audio / graphics / usbport (yes, I've remembered, sometimes usb.sys is causing it).

This started happening a little while back, i was gaming and noticed my fps drop dramatically, checked my cpu usage and it was at like 40-50%, 20-30% of that usage being system interrupts. So ive been doing tons of research for the past 3 days trying to
figure out what could possibly be causing this.
I found out acpi.sys was the issue so i did more research on that, I did some registry hotfixes, and other suggested things but nothing has seemed to work.
In process explorer the thread is named "ACPI.Sys+0x1af7c"
I've changed the acpi settings in bios, then reset them back to default, that did nothing.
I have literally ran out of ideas,

Lenovo system update offered me today to install a critical update - ThinkPad BIOS UPDATE US - 8.1/10 [64], version After the installation and windows restart, I have noticed that the system performance has gone down drastically. Process list inspection showed 'System interrupts' using 25% of the CPU, which basicaly means that a single thread is utilizing 100% of 1 logical processor. I've inspected the system log, and 1 error stood out: 'BcmNfcIc driver has failed initializing NFC device.' System log was flooded with these messages. First event was logged after the windows was restarted (after the bios update). I ran the Lenovo System update and installed the offered Broadcom NFC Driver [64] It didn't help to resolve the issue with the NFC device initialization and consenquently CPU usage. I went to the device manager, and disabled 'NFC SMBus Device' under the system devices. CPU usage went down to 0%. Now the question is, did my NFC device actually fail, or the new BIOS update introduced this issue?

Hey all. So I upgraded to 8.1 from 7 and I faced this issue where I have the same exact programs opened that I had back on windows 7, but now they are generating alot more CPU usage. I can't find any solution to this, other than installing 7. That fixes
it. On win 7 with the same exact enviroment (same programs opened, same page on google chrome opened, same exact everything) I get 1-4% cpu usage which is great. On win 8.1 however, with again everything the same, I get 18-30% cpu usage.
And it's all caused by windows' processes and stuff. Can't really shut them down because things won't work then.
I kinda like win 8.1 so I don't wanna go back to 7, but since my performance is crippled, I might have to. Any suggestions are much appreciated! I've tried some things that I found on the internet, but nothing seems to fix it.

A friend of mine has the same mobo and cpu as me, but when I did a test and created the same exact enviroment as on my pc, the usage doesn't go above 5% when idle.
I dunno what to do at this point.
Here's some screenshots of my task manager:
On this last one you can notice that there's a misterious difference between the user cpu usage and the overall, idk what causes that.
I tried doing clean install and have absolutely nothing installed and it still stays at around 15%

I recently noticed high CPU usage from NT system and kernel which was affecting my performance, noticeably when gaming. After doing a performance analysis, I found this in interrupts (attached screenshot)

After looking around, I'm still not sure of the cause as my PC is fairly new and was wondering if anyone could help me?


A:Hal.dll high interrupts CPU usage

Interrupts don't really mean a lot. An interrupt is generated every time you move your mouse or press a key on the keyboard. If you look at the average duration it's .009ms or 9/1000th of a millisecond. The total accumulated over the entire period in your data amounts to 13 seconds. I don't see the period covered but that's not a lot.

It would probably be better to analyze what else is running while you're trying to play a game. Services, background programs, auto update, etc. can eat up cycles. You might try a Clean Startup and see if that improves game response. OEM bloatware and crapware are heavy burdens on a laptop. Most don't do anything that can't be done through Windows.

Forgot to mention: You don't have many specs listed but running out of memory is another bottleneck on performance.

Hello, I have noticed that, for the past few weeks, my procexp has been showing the interrupts using upwards of 75%-100% of my CPU. I know that the interrupts deal with the hardware of your computer.

I have been searching around to find a fix and the most common solution was to switch the IDE channels to DMA mode (PIO mode caused the high cpu usage) but all of mine were in DMA mode. I have used driver sweeper programs to remove my video card, modem, etc.. But I have had no luck. I've switched out hardware, changed bios settings, booted up with any startup programs.. Nothing.

I have scanned my computer for spyware, adware, virsus, trojans.. Etc.. I had a few pesky adwares installed but nothing significant enough to cause this problem.

I came across a program, made by microsoft, that would watch the interrupts and log every driver that was using the CPU time. I have uploaded the file below. Hopefully you can make better sense of it.. It seems to me it MIGHT be a video card issue because it counted A LOT of ISR with the "VIDEOPRT.SYS" driver? Possibly my video card is faulty?

Anyways, if you have any insight into this that would be amazing.

Thank you very much!

Wow.. I fixed it.

I feel pretty dumb. Hopefully anyone googling this same problem will learn from my sillyness. Yes, it did have to do with my videocard (VideoPort.sys). It turns out the card was a little loose.. After pushing it back in the Interrupts dropped back down to ZERO. I can't believe it. I tried puling the card out ever-so-slightly and it jumped back up. Amazing

Thanks anyways, this is an awesome forum. Hopefully someone will stumble across this and find a solution to their problem

Hi guys, just out of curiosity I ran a performance diagnosis (the Windows system tool) of my computer and one thing caught my eye...
Warning: High average interrupts / processor. This machine has 4 processors and 4 network cards. Total Interrupts/sec on the machine is 53676. The average interrupts per processor per sec is 13419.This is one of the warnings that popped up in the report, but I have no idea what it means, whether it's normal and whether it can be fixed or not??

Sorry that the information is extremely vague, but I do not know what information would be needed in order to diagnose a problem/explain what it means.

Could someone please help me find out what is going on?
If you need any information at all just ask and I'll update the post with the relevant information.
Thanks in advance!

(I am running Windows 7 x64, Service Pack 1)

A:Performance Monitor says high interrupts per processor??

While I'm not real knowledgeable about this issue, I do believe that it means that there may be either a hardware or a driver problem (from this topic: High CPU - Hardware Interrupts - Sysinternals Forums - Page 1 )

I'd suggest looking through your event viewer for recurring errors that may give you a clue as to what's misbehaving. I've researched this issue once before, and the large number of network cards (this is actually normal) caused me to investigate the network drivers and devices.

Check in Device Manager for any issues with Network Adapters. Then obtain the latest network device drivers from the device manufacturer's website.

If that doesn't fix things, we'll have to ask for further assistance from those who know more about this than I do.

Hi, I'm new here and I'm not good about any of these so please be detail.
My problem started when I installed a software that required me to use daemon tools. I did, eventhough I don't really know how it works (I just click and click). It is something about mounting and stuff. So I did, and the installation went okay.

After the next restart, windows started to find missing hardwares and asks me to install it, all 3 or 4 of them. I didn't at first, and realized my cpu usage gone to 50-60% without running anything. So I browsed forums, and it's not because of DMA reverted to PIO or stuff. I downloaded Process Explorer and noticed the hardware interrupts are the cause of this high cpu usage. I checked device manager, and found out that under the IDE ATA/ATAPI Controllers, I have multiple channels. Before this, I only have 1 primary channel, 1 secondary channel and 1 standard dual channel PCI IDE controller but now I have 2 for each channel I stated. I suspect this is the problem, but I don't know how to deal with it, and I googled it, nothing similar ever came up.

I tried uninstalling, reinstalling and updating the drivers. Sometimes the hardware interrupts disappear and I don't know why, but the next restart will trigger the problem all over again.

I really don't know what to do and I hope someone could help me.

Thanks in advance.

I ran DPC latency Checker and got an average of 1014, with the message that some device drivers on this machine behave badly, a similar program gave me the same details, LatencyMon.
My BIOS was recently updated (about 3 months ago) with the latest version, and everything was running just fine.

Hi! So my friend has a PC with Windows 10 (installed from USB-Stick with the WindowsMediaCreationTool). It ran fine for about two weeks, which is when the problem started: The "System and compressed memory" and "System interrupts" processes taking up *a lot* of CPU time even at idle. https://i.imgur.com/cDDZhRC.png
The system is usable for web browsing and such, but everything that needs performance like games is severely hindered by these processes. It also doesn't allow the processor to ever go into a lower C-State ("power saving mode" / reduced multiplier), it runs at full speed all the time. Needless to say this is *extremely* annoying and defeats the purpose which the PC was built for in the first place (playing games). Now, this is what we have tried so far: After I couldn't find a solution, I just told him to re-format since that usually solves these kinds of problems. And it did! But only for around 3 days, then the problem was there again. Disconnecting all cables except for the monitor and power cables didn't help. Disabling devices in the device manager didn't help. Disabling automatic updates and Windows defender didn't help. So I just told him to re-format *again* just to see at what point the problem would appear. But this time, right after the system was booted up, and the usual update and search indexer processes were done, the same problem appeared again. So he tested his memory with memtest86, but found no errors. His SSD seems... Read more

Whenever a USB device is plugged into my laptop (any of the USB ports), the CPU usage goes way up. It stays up even when the device is then unplugged, and the only way to bring it back down is to either reboot, or to go into "sleep" (when Windows resumes the problem is gone).

The Windows 7 resource monitor indicates that the problem is System Interrupts - Deferred Procedure Calls and Interrupt Service Routines. .

I have updated my drivers for each thing, and that has not helped. Not has lots of Google searches on this problem.

I'm using the NETGEAR WG111v2 54Mbps Wireless USB 2.0 Adapter #3 with the lastest version from the website. I'm not sure if this adapter is the problem, I just think it is based on the fact the internet drops at the same time.

It turned out to be "Intel« Serial IO host controller driver", specifically this: iaLPSS2i_I2C.sys.The version installed is 30.63.1519.07.In this link I can find other versions, but it's not clear why there are 5 separate "latest" versions, nor it can be understood if they can be used here.Regardess, I tried version 1.3, and tere was no change. The driver did not get replaced either.I also tried to remove the Intel Serial IO from Control Panel, but uninstalling it did not remove the driver at all. I am still getting about 15%  of CPU wasted by system interrupts. Is this a known issue? What can I do to fix this? I know this is a long shot, but I'd like to get a techincal response if possible. This is an ultrabook, and wasting resources is not helping the cause. Thanks

A:Yoga 900 High System Interrupts Issue

Hi gaga and welcome to the community,
I'm not seeing this issue of high cpu usage, but I do see 4 usages of your same driver in the system components in Device Manager.  If you knew which of these is causing the high usage, you can disable it in Device Manager and see if it improves.

Hi, I just about a new Acer Aspire Timeline 4810T laptop. I replaced the stock hard drive with an OCZ Summit 120GB SSD and installed Windows 7 x64. This makes for a very quick system that still has around an 8 hour battery life. Normally it's great.

However sometimes it becomes extremely sluggish and the CPU is pegged out. When I go to the Resource Manager it is showing that system interrupts are consuming all of the CPU usage. The only way to restore the system is to restart it. I can't seem to figure out how to track down the culprit.

I've looked around the web and found some similar issues from others where they recommend disabling HD audio in the device manager. I did that for one of the listed audio devices. The other I installed the Vista x64 drivers for the audio from the Acer website. This seemed some what to help, but not completely. Every once in awhile I still get the issue and it makes the laptop unusable, not to mention eats up the battery much faster.

Anyone ever seen this issue or know how to track it down?

A:100% CPU Usage System Interrupts on Acer Timeline

I also had problems with the 100% cpu-system interrupts.

I noticed this, when I copied data to an usb device (pendrive or hdd, doesn't matter).

My usb card reader caused my problem. Im not sure the same thing with u, but if you have a buil-in card reader, try to disable it in the device manager. Check Disk Drives tab, and if u see any Generic USB Card reader or something like that, disable it.

About 2 or 3 days ago I've been having a problem with my Acer desktop which is running Windows 8.1. Whenever I move my mouse I get huge spikes in System Interrupts which causes an unbearable amount of lag. The only way that I have found to temporarily fix this is to unplug my mouse from the USB drive and plug it back in.

After about 20-30 minutes though the error slowly comes back, the usage will be at about 10% after 10 minutes everytime I move my mouse then after about 20 minutes it gets to an unbearable 20%. And so on. I have even tried using a different mouse, one wireless and the other optical. The problem persists on both Mice.

Now I am quite confident that the new update has caused this error. I have been finding that many other people are experiencing the same error that I am having and yet no one has a solution and many of the staff are trying to blame something else, such as Malware. Now I know this is complete crap because

1. I barely recieved my desktop 3 weeks ago and has worked perfectly fine until just a few days ago.
2. I barely even use the desktop, all I use it for is YouTube and Minecraft. I don't look up porn or go into any suspicious websites on it, I do all of that on my laptop.
3. I have many programs to protect my desktop on it from stuff such as viruses, and even keep all the drivers updated, defrags, etc. All of the programs I have on my Desktop are also on my laptop, yet on my laptop I download porn and all that bad shiz.

A:March Update causing high System Interrupts?

March updates were quite a big bundle, I think just over 30 from memory. You can remove (uninstall) the updates but its a last option. Other options would be to try system restore and pick a date when you knew all was working OK or to try W8.1's 'refresh' feature.

Hello to everyone,
OK, I am new on this forum and I am here because I need some help. I have problem with very high CPU usage on my computer and I don't know what is cosing it. Every time I start any of programs (Photoshop, TuneUp Utilities, Dreamweaver, even IE or Firefox, .... and every game I start ) my CPU goes crazy and lately, because of that, computer just turned of a couple of times (with blue screen on).
I started to Google a solution for this but I could not find any. I have laptop and it is not a bad one and it should be able to work with these programs (like it used to do) but simply it can't do anymore. I don't know if this is because of drivers, windows, svchost.exe, virus (I think that this is not causing it because I had run almost every protection that I know I didn't find anything on my computer [Programs: Malwarebytes' Anti-Malware, Spybot, Avast, SUPERAntiSpyware ] ) problem or something else but simply I can't locate my problem

Here are my laptop specifications:
Acer Extensa 5635G
Intel Core 2 Duo processor T6570 (2.1 GHz, 800 MHz FSB)
NVIDIA GeForce G105M Up to 2303 MB TurboCache

Please tell me what other informations you need so that I can write them here.

I know that this is pretty wide problem but still hope that somebody could help me. So thanks in advance

A few days ago I went ahead and installed Windows 7 on my pc. But ever since then I'm having a lot of problems with my computer. The first few minutes my computer works as it is supposed to but after a while it starts to get more and more problems.
For example if I open my tv app the first few minutes after a restart it works all fine but if I close it and re-open it again, the images and sound start to stutter and every couple of seconds everything hangs (sound, image and even my mouse). At those times I can see sudden peeks in the CPU Usage (at the performance tab in Task manager). At the "recourse monitor" i noticed that every time the cpu usage shoots up, a process called "System Interrupts" uses most of the cpu power.
I also have the idea that when scrolling down, on some pages it goes a lot slower than when I still had XP. Also if my pc is on for more than a couple of hours even my internet broser (chrome) starts to get more and more issues. It starts to get more irresponsive, when I'm typing every now and the browser hangs for a couple of seconds and then fills everything I've typed in.

At wits end.
My laptop is so slow it is almost unusable. CPU usage is 30-40% constantly, even in safe mode with practically everything disabled. All caused by System INterrupts.

I have cleaned out an unused software and datafiles, removed AVG (relying on Windows Security Essentials and Defender with Malware Bytes uploaded and run weekly then uninstalled). I have defragged and run full virus/security checks.
We have tried disabling drivers one by one and using latency monitoring programme suggested elsewhere on the forum, but nothing makes any difference. The latency spikes are irregular and in amber but not going into the red.
Laptop overheats seriously, and I only get 1hour out of NEW HP battery (problem started before battery was replaced but we have checked the driver for this). One USB port has stopped working entirely after being a bit dodgy but I again disabled drivers and no improvement.
Keyboard also seems to miss characters regularly which looks to me like it is due to slow reaction

Can anyone suggest anything I haven't tried, or do you think this is a hardware problem and it needs to go to a clinic? I suppose I could always buy a new machine.


A:System Interrupts 35% CPU usage in safe mode HP Pavilion dm4 64bit

OK maybe we should have done this first.

I removed the battery and the CPU usage fell massively but was still spiking to using 35% of CPU frequently.
A bit more detective work and more searching online threw up issues with HP wireless assistant.
We updated the HP update - this did not update my old version of HPWA, so we downloaded v 40.0.10 (impossible to find on the HP website but we did find it on another site for free) just in case we needed it - ie in case the wireless button stopped working when we disabled HPWA.

THEN disabled the old HPWA - no problem with wireless button or internet access so have not installed the newer version. This fixed the spiking of CPU and my keyboard works fine (haven't yet checked the USB port).

THEN I experimented with putting the battery back.

Miraculously, CPU usage is down to background 0% and the fan has stopped whirring away continuously.
I am now experimenting to see if battery lasts longer then 1 hour this time.

As the title states I am having an issue with CPU utilization on a fresh install of windows 7 professional 32 bit on a Acer aspire D255 netbook. Basically the CPU always uses 30% of the processor even when idle and nothing else is going on for system interrupts. The problem exists with full drivers and windows updates or a fresh install. I am stumped on how to troubleshoot the next steps.

I am a system admin by trade so all the basic troubleshooting has been done. I have even tried several different ISOs of 7 profession on a flash drive via Windows 7 USB tool.

I only notice this strange CPU usage in windows, when I use parted magic via hiren's USB drive the processor does go down to 0-1% when idle. I have ran hardware tests like MRI disk and memtest to rule that out and they run clean with no errors. I believe the problem is strictly in Windows and I would love to find out what it is if someone here can help me.

Lately i have encountered a frustrating high level of CPU and Memory usage. When i first started my computer with no application running, i noticed the slow loading, and that's when i saw my CPU and physical memory rocket-up to 60% and 2 gigs of ram. To make the matter worse, the physical memory usage increases gradually until it reachs near 4 GB. At some point, the free P/M reaches 0, the CPU usage is unstable ( somestimes its 20% and somestimes 90%). There's another strange thing is the sudden appearance of svchost.exe which i haven't seen since i bought this PC. I've searched through the forums and found several methods ( Virus scanning, process explorer, turning off several unneccessary services and even re-install windows ( C driver to be specific) ) but sadly nothing worked. I've also disabled the apps that i recently added to chrome ( as i thought they were the causes), but the P/M Usage still stays at 4GB. The only thing that i can use with getting lag and stuttering now is google chrome, although its a horror just looking at how slow things are. Please help me to find a solution, i have a lots of important document and i can't stand the thought of having to completely re-boot my whole computer. Thanks a lot!

Whenever I run my computer plugged into power, it runs perfectly as expected. But as soon as I unplug the computer, its performance dramatically decreases. This is extremely noticeable in games.

I have ensured it is on the "High Performance" mode, and have checked the advanced settings for this mode to ensure that it is the same for both battery and plugged-in.

My graphics card provides no options for its operation in battery mode, so I am now stumped.

I don't have anything running either, my anti-virus is disabled and I am running only system critical processes (apart from the application/game that is running ever so laggy).

My graphics driver is the latest MobileForce driver (since nVidia hasn't released one for my card in Vista...). It works excellently when plugged in.

Does anyone have any suggestions?

Hi everyone,

I have some problems with my relatively new dell laptop (4 months old, and the problems are present for like 3 months), which include: Very high RAM usage: 80% when only Microsoft Edge is turned on.
Very high Disc usage: 100% almost at all times
Low performance in games (the laptop meets the req. for a game, still cant handle it; low fps, stuttering, freezing.
Can't handle videos sometimes: the sound works but video is frozen, or video Works and sound freezes.
Sometimes VERY S L O W: sometimes when i open an app, it turns on after a minute; when i type, the letters appear after a while.

I have already reset it to factory settings and wiped the HDD, didn't help. I have a lot of free space on HDD, no dust in the laptop, no physical damage, no viruses, no (useless) background proceses.

I have already had a call with a dell technician (he did some changes and driver updates), also didn't help.

Do you think a RAM upgrade would solve this? Or do i have to take it to service? Or anything else? Please help.

I sincerely hope someone can help. I do not consider myself really computer illiterate, but this is where my understanding ends and I would truly value all help offered.

I have a Toshiba Satellite Pro M70 of 2 yrs old and I am a definite advocate for Toshiba. However, my operating system is slow. Average day usage with Internet Explorer and Office 2007 is a painstaking process that takes too long. I have had conflicts with Trend Micro Internet Security 2008, which works perfectly.

But starting up the computer takes ages. CPU usage is usually high and System Idle Processes as well. I have reinstalled Windows XP from the Toshiba Boot DVD already 4 times with starting fresh and installing everything time and time again. Each time after getting everything up to speed again, the performance is disappointing.

I have extended RAM to 1,49 GB which made little difference from the original 1/3 of RAM. It seems that something is slowing down the computer, but this is not visable in the processes; other than quite a few svhost.exe processes that take little processing capacity nor CPU usage.

I have used Windows Gold Certified Uniblue Power Suite with a good registry cleaner. This helps a bit, but after a couple of days it seems to get only worse. I have an Intel Pentium M 1.73 GHz processor. Research online reveals that Trend Micro IS 2008 is quite good and demanding little capacity in comparison to competing security packages.

A:Re: Satellite Pro M70 - High CPU Usage - Low Performance


I doubt this could be a hardware issue? I mean a CPU usage could goes up if a certain service or applications would run in the OS background.

Usually the Antivirus applications are one kind of software which could cause such issue? I had a Norton System works installed on my notebook and this software needed a lot of hardware resources which slowed down the notebook?
Furthermore some Toshiba applications which are installed and running in the background could affect the performance. But such applications are needed in order to use all notebook features?

However, in msconfig you could disable it.
Start msconfig -> startup tab and disable some processes which are not necessary for you.

Furthermore you could use the CCleaner to clean the OS and the registry?

I've just started having a problem where my computer becomes periodically unusable for chunks of time, like 30-60 minutes.
Everything is going along well and then it slows down to a crawl.
In the task manager, under performance, I see a crazy amount of activity, sometimes pegged at 100%, sometimes less. But even when it shows the cores around 50-70%, I can't even right an email without significant lag.

It's a Dell, Windows 7 x64. i7 processor, 16gb of RAM.
The thing is, when I look at the applications running, none of them account for all the activity.
When I look at processes that doesn't add up to all the activity I'm experiencing either.
I got something called Process Explorer which gives a more thorough list but that doesn't show very high activity either for any process.

I ran several virus scans while the computer was booted into safe mode with networking. One of them caught some stuff, but subsequent searches came up clean.

I ran a tool to clean up the registry.

I can't figure out what is causing the problem and I don't know what to try now. It's weird because after a while the activity will just stop and I can use my computer again. And then just as mysteriously the problem will start up again.
Thanks for any help.
