Preferred Solution: High DPC Latency, Startup Interrupt in Taskmanager - excessive CPU usage

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Not sure if I'm posting this in the right subforum - I've been having crackling/popping audio issues while playing games and using audio programs, and I've been trying to isolate the source/fix the problem, to no avail.

I ran LatencyMon for almost an entire day without really touching the computer or running any programs. Here are the results. Run on a Lenovo Thinkpad T530i.

CONCLUSION
_________________________________________________________________________________________________________
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. Check for BIOS updates.

ive been getting about 15% CPU usage from DPC/ISR service (Deferred Procedure Calls / System Interrupts) when copying files from the HDD to external devices and vice versa and when I download files to computer, the downloading part of it gets worse if I install a firewall like Outpost (it went up to 40% when downloading at 12Mbps on my wifi with Outpost on - ive since uninstalled it) - so originally I though it was my wifi card but it does this with it disabled when i transfer files out to HDD (when I transfer files internally it doesnt happen) - I ran the Windows SDK Performance Monitor which showed it to be the NDIS.SYS that caused most of the problem. ive searched and asked for help on other forums but had no luck, one person told me its a bug in windows 7 and everyone gets it??

like I say it happens when downloading (the faster the more it does it and it does it more on Wifi (15%) than LAN (5%) and it happens when I copy files in/out of laptop's HDD - ive been told this 'hidden' process using even 1% is abnormal

the process is hidden in Task manager and does not show so dont use that to check, even if this background service uses 99% cpu taskman will still show as 99% idle (it runs behind idle as its not expected to use more than 1% cpu...so im told) - only in resource monitor or process explorer can you see it

see my screenshot below for example

can anyone help me with this please? Win7-64bit / Dual-Core AMD / 2Gb / Acer Aspire 5050 laptop

Hello all,
The problems i'm having are as follows. I will start up my computer which will take a lot longer than it used to, the fan starts working overtime and gets louder and louder. When i look at task manager i can see 'aawservice' building up to 200k+ memory and if it's left for any more than 2 minutes my computer just turns itself off. If i get to task manager before it turns itself off i can end the process myself but it takes about 3-5 tries before it goes away, or appears to go away. Today i did the same strenuous routine just to get onto my computer however when I manually stopped 'aawservice.exe' through the task manager 'ccsvchst.exe' seemed to take its place and decided that it would send my memory usage through the roof.
I also have many duplicate processes. 'svchost' which i currently have 9 seperate processes running at this time which amount to around 75k of memory being used. 'ccsvchst.exe' which i have 4.

Also i have a problem with mozilla where you will enter a site into the address bar and instead of taking you there it will search for that site through askjeeves.

Hey everyone,

Happy New Year

After about 24 hours of booting my computer, I have seen my DPC Latency spike tremendously. At first, I thought this was an issue with my network card (since disabling it would drop DPC Latency), so I bought a new card. The problem didn't go away, so I realized it was something else. High DPC Latency is a problem since it causes audio and video lag.

As I troubleshooted the issue, I have realized the spikes were caused from network activity. For example, when I am seeding [not necessarily uploading] many torrents or am loading a website, it shoots up.

See below for a before and after screenshot respectively.

Does anyone know what may cause this and how I could prevent it?

Thanks in advance for your help,
Dan

I set up a new system 2 months ago (mobo+cpu+ram+gpu). Fresh install of w8.1 with drivers from manufacturer install disk. I started getting huge lag spikes, which appear mostly when dragging windows around on the desktop or wiggling the cursor around. Basically the whole system just halts for 0,5-1 seconds. Also happens mkv playback, browsing etc, but most notably when moving the cursor.

I thought I messed up with the installation of windows so I reinstalled it again. No help there, so I started going through things that could be causing it, mainly bios settings, mobo drivers and various windows settings. Especially the management engine driver and HPET timer forcing/disabling. I thought I had it fixed for about 5 weeks, which it worked perfectly.

Couple weeks ago I upgraded my cpu. The system was 100% stable with 4,3ghz cpu overclock and some gpu overclock, IBT very hard passes, some tough memtests and 30 hours of Dying Light without any problems. Everything was fine until I needed to fix a non-related mobo network driver memory leak. Just a simple registry fix to stop network monitoring at system startup, but I also ran ccCleaner. After this the problems started again and its unbearable.

Mouse movement: I've used 3 mouses and the ones with high polling cause the worst problems. With 500hz/1000hz the interrupts become apparent eg. full second halts, but with 125hz settings its not that apparent. The latency is lower, but still there are problems, low fps in games for exam...

Since I upgraded from Windows vista home premium 64bit to windows 7 home premium 64bit my computer has been taking a long time to start, the longest wait is after the password screen until the desktop loads. Also my cpu usage is very high for about 10 minutes after startup. I looked to see what was using so much of the cpu, and it seems the culprit is something called System Interrupt. I have no idea what could be causing this, any help would be greatly appreciated.

Hey. You probably have unneeded apps starting with Windows. Type msconfig in the start menu search box and hit enter. Go to the startup tab and uncheck the unnecessary apps and save. Reboot to test.

A better method is to use the information available from msconfig then use Regedit (also from start menu search) to follow the keys and delete.

Hi everyone,

When turning on my PC, CPU usage rockets up to 100% for a few minutes. This has caused the PC to shut down on multiple occasions because (I'm assuming) the CPU got too hot (limit is 100 degrees).

The main culprit of this is a task called "Windows Compatability Telemetry," which can sometimes have 4-5 versions of itself each taking up around 20% of the CPU each. "Antimalware Service Executable" can also take up a large amount of CPU usage for a few minutes. I haven't yet taken any steps to rectify this problem, and I never used to have this issue.

Can anyone help me disable these processes (if they aren't 100% needed)? Or at least help make them not be so overbearing on the PC? Thanks.

I have a question about ping times, latency, and jitter.

I believe I understand the concept of jitter. If I ping www.google.com, and get some results of 10ms and others of 100ms, my jitter is 90ms; right?

If that's true, here's the question I have:

Is it ever preferable to have a connection with higher latency but less jitter? For instance, would it ever be better to have a 100ms latency with zero jitter than it would be to have latency that fluctuates from 10ms to 100ms?

One possible application I could think of would be something like VoIP or videoconferencing, where (perhaps) you would prefer consistency, even if it means higher overall ping times.

I recently installed Windows 8.1 on my Inspiron 7520 and I noticed that during the startup the disk usage is around 98/99% of my Samsung SSD 840 Pro 120gb.
I saw a lot of posts where the users complain that, during this high usage of the disk, apps don't open, the system freezes around 5 minutes and after that, there are random high usages, even on idle. But in my case this high usage lasts only few seconds (around 30s), I can open some apps with no problems and never happens again on idle, only if I restart Explorer.exe. If I restart it, it happens all again.

My question is : Is it normal? The high usage only on startup? My only worry is mess up with my SSD due this usage.

UPDATE: On Performance Monitor, the process which writes a lot is System. I disabled every 3rd party app on startup.
Thanks a lot!

A:High Disk usage (98/99%) ONLY on startup

Is it normal? The answer is no! Have you looked at your event viewer to see what warnings, errors or critical errors you are getting? That might provide you some insight of problems. Also, have you checked Action Center and used troubleshooters available there? Just some suggestions that might help identify. Hope you get it solved....

hello, I have been having the Issue with my PC, a HP dv8000 with WindowsXP SP2, I use Firefox as my primary browser, but i use IE for some online school material, and not for any other use. I use BitDefender as my Antivirus. I have been having a long start up time at the black splash screen, and then a high cpu usage at the desktop when running programs. the solution that has thus so far that seemed to fix the problem was doing a Destructive System restore, which appeared to fix the problem, but today after doing a restart due to some suspicion the problem may be back. I have not installed any hardware, nor major software that I would suspect not cause any change in preformance of the system, they are application and game software. Today, when this problem occurred, I was merly browsing the internet and using a music player, when the sound was being a bit choppy, and I noticed a high cpu usage, which is why I did a restart. I have not received any error message in relation to the problem. I have done a Hijackthis log, and no infections were found.

A:Long Startup High Cpu Usage

If there is a single process consuming abnormally high CPU time -- that could account for all your symptoms. When you open the Task Manager -- select the processes tab and try to identify the individual process. If it is associated with an obvious 3rd party program -- either remove and reinstall the program -- or just uninstall it completely if it is not vital.Another method to troubleshoot is to use "Clean Boot" troubleshooting techniques described here:Run msconfig and select the "Services" tab. Check "Hide Microsoft Services" and then disable the rest. Also uncheck "load startup group" on the general page.See one or both of these links for detailed information. The second is for Vista -- but it is actually the best written and applies equally.http://support.microsoft.com/default.aspx?...kb;EN-US;310353http://support.microsoft.com/kb/929135Now restart and test the issue at handIf no problems, run msconfig and recheck half the disabled items on the Services tab. Test again. If the problem recurs, UNcheck half the items you just checked to narrow down the culprit.If the problem didn't occur, check the other half, so all the Services are enabled -- proceed to do this on the startup tab as well.Get the idea? You want to isolate the problem to a specific startup if possible.Note: if you already have items unchecked under msconfig > startups and are in ?selective? startup mode ? you should note what these are before beginning.

Just watching it, it takes up all of my ram, and it is pretty bad when this happens. If I remember correctly it alone has taken up over 1GB. Over time of the computer being on, it gadually gets smaller and the computer acts more normal. I'm not sure if any of the scans I did will help since it was all after the computer has been acting more normal. The only thing I downloaded recently was an online game which is still in Open Beta (Its called Perfect World) but my friend also downloaded it and hasnt had a problem, plus this started a few days after I downloaded it.

Hello, I have recently been having the issues of a unusually long Startup starting at the black "splash" screen to when my desktop becomes usable, the time is roughly 7 minutes to start up. along with that, my CPU usage has been very sensitive to more then one program running, a example is my internet browser and windows media player open, normally these two programs open at once would not do anything to the preformance of my PC, but when I have WMP open, the music that plays is choppy, and jerky. I have no idea if I have a virus, corrupt files, or faulty hardware. I have noticed this message in my eventvwr.msc under system "The driver has detected that device \Device\Harddisk0\DR0 has predicted that it will fail. Immediately back up your data and replace your hard disk drive. A failure may be imminent." however, I have done chkdsk and gone into the BIOS at startup via F10 and done disc checks, which both the quick and comprehensive passed, so I don't belive my hardware is faulty. But I am worried, as this preformance in my PC is unusual and I don't know if it is a virus, adware ect. or a damaged file. I have tried system restore, but it says that it is unable to do a system restore after the restart, which takes along time as mentioned above.

In fact, I think using CCleaner back then actually even deleted some Startup files that helped (including one that displayed the volume increase and decrease by keyboard buttons) but yeah, they're somewhere.

Anyway, the Startup's slow. CPU Usage is high, around 20s or so when idle, which is probably not so good. It used to be higher, but I used CCleaner to clear caches (or something like that) about a month ago, so it's slightly better.

The laptop was bought around the start of 2007, so I figure it's uh, quite advanced in age and not at it's prime anymore, but I'd like to know if there's anything I can do to make it work well again. At least not take forever to start both the computer and programs (like Firefox), you know?

C: Drive has 2.39GB out of 37.3GB left, and D: Drive has 538MB out of 37.2GB left. (I use the D: Drive for torrents, so when I'm done with the shows I usually delete them, they're taking about 7.36GB now).

Also, AVG Free has stopped making noise and generally being annoying, so I don't know if it died and I have to update or something. It's not coming up at Startup, that's for sure. I am seeing avgcsrvx.exe, avgnsx.exe, avgrsx.exe and avgwdsvc.exe running in the Windows Task Manager though, so idk.

Hello

So I had this problem for a while now and it's really annoying. Just after the "Welcome" message the PC keep loading for few mins and I can hardly open any software due to this high memory/CPU usage.
I already disabled some startup programmes/services but that didn't help

Is there a method to find out what my PC is doing? sometimes I see "trustedinstaller.exe" process, not sure what's getting installed/updated.
Also I think that this problem have something to do with VMware but I'm not sure.

A:Svchost.exe High memory usage at startup

Hello Master12,

What is svchost.exe? - Windows Help

Svchost.exe is a process on your computer that hosts, or contains, other individual services that Windows uses to perform various functions. For example, Windows Defender uses a service that is hosted by a svchost.exe process.

There can be multiple instances of svchost.exe running on your computer, with each instance containing different services. One instance of svchost.exe might host a single service for a program, and another instance might host several services related to Windows. You can use Task Manager to view which services are running under each instance of svchost.exe.

It's normal for a computer to take a few minutes after booting-up for it to load of all applications.

Thank you,
VinnyBuxton

This is a Dell Optiplex running Windows 2000. On startup, winlogon.exe consumes 30 to 90 % of cpu resources for a minute or more, then returns to normal (0%). I've verified that the system is clean of viruses/spyware (Adaware, Spybot, TrendMicro housecall, clean HJT log, etc.). I recentlyinstalled AVG antivirus, but disabling this application has no effect on the winlogon problem. Also, this system has a corrupt user profile and II've recently created a new user profile and copied documents over to the new one. And last but not least, the winlogon problem does not occur in Safe Mode.

Hi,
Ok, this is my problem:
Whenever I startup, the computer usage runs way up to 80-100% and it takes forever to start a program. It immidiately starts this whenever I just turn the computer on, and I hear it because the sound that Windows makes at startup gets scratchy and stutters.
Once it has started up, if I click on iTunes (for example), once the program pops up and I click on Play, every song stutters. It stutters only at the beginning and then it smooths out, but it does it for every single song played.
When I put in a DVD it stutters but it stutters throughout the movie.
It just started doing this randomly. It never did it before. The only thing that is new is that I played an old movie file that must have been corrupted or something because the file wouldnt play and I tried to copy the file (from an external hard-drive) and paste it onto the desktop to get it to play. It did eventually play it, but it took a long time for it to load and play.
I tried looking for answers at the microsoft website and the problems they showed that looked similar seemed to suggest that it could be solved by downloading all of the latest microsoft uploads. So I have been doing that for the past 24 hours and it is my first line of solutions. I just wanted to ask here as well in case that doesnt work.

Hello,

I found many forums with this issue but none really gave a decent solution.

I have a new laptop windows 8.1 (64bit) 8gb RAM i7 processor which should be sufficient for the software I use.
however on start-up my memory is already at around 80% and stays like that.

The most seems to be caused by servicehost (network restricted) (11)
another program is IAStorDataSvc (32bits) even after i updated Intel Rapid Storage it still seems to take some memory.
(My system settings are in Dutch but I guess it's pretty much the same as in English)
Has anyone an idea what could be the cause of the massive memory use?

Hello,

My computer runs on average, 70-80 processes which use almost all of my available memory. I just recently installed 4 GB of RAM since before, I had 2 GB, and almost always it used 90% of it.

Hi!
 
I'm back.  I had this exact same problem a couple of months ago and we fixed the problem with a total restore.  My system was working beautifully up until 3 days ago.
 
Upon start up my system freezes. I login. It boots up, full screen with desktop icons. But freezes when I try to move the cursor. The clock time freezes at that point, also. I reboot and login under 'safe mode' with networking.
 
I would have written sooner, but I had a deadline to meet today.  Now that, that's completed I have all the time to work on this.
 
Before I try another restore, I'd like to see if the problem could be fixed.  I noticed, about a month before, my system was experiencing high CPU usage.  To the point where my fans would go on high alert.  This only happened when I was on certain websites that used flash.  This message would come up:
 
Shockwave Flash may be busy, or it may have stopped responding. You can stop plugin now, or you can continue to see it the plugin will complete.
 
It never crashed my system, but I would immediately exit the website and the fans would die down.  Today in safe mode with ntwkg, the same thing happens. The message does not appear, but my system gets really hot and fans are high.  Just like in regular mode, I shut down the websites causing the problem and my system returns to normal.

Hi,

This is the XP operating system on my backup hard drive since the first hard drive I had XP and linux on it, i tried to remove linux but unfortunately did not restore the boot loader settings so I am unable to boot using the first hard drive but it has my work on it so now Im using my second hard drive.and I can still access my files.

So, I have updated everything but everything seems to be going well. I installed spybot and nothing shows up in the scan.

Sometime into it, my startup became much more slower than usual so I tried to use bootvis to optimise my startup performance but I think this made it worse.After I ran bootvis, it made load times longer and I cant find out where I can reverse these changes.

The problem is that whenever my computer loads up into the main desktop, it takes about 5 minutes to load and the hard drive makes a constant low sound which I think it is doing something like scanning through the drive to find something. Basically, it loads the icons for the LAN and the wireless internet. The others like DU meter and eset take about 5 minutes to appear.

Once this is loaded, whenever I try to load my computer or check services.msc, the CPU usage increases by 50% for each. I.e. when I double click on my computer CPU usage increases by 50% when is I try to check out services.msc, it increases by 50% as well for the mmc.exe service.

Hello everyone, I've been having a very weird problem recently, in which I BELIEVE is involving high physical memory usage. Sometimes I will be doing things such as playing a game, or watching a stream, and my computer will run fine for a little while. But at random times, my computer will majorly slow down and sometimes even crash. If it doesn't crash, sometimes it will get so slow to the point where I have to hold down the power button and manually shut it down. Every time my computer slows down I notice it is using a TON of physical memory. It's actually happening right now. My computer is going very slow and it's using 6.22 GB memory out of 8. There are no big programs running right now, so I don't understand why it's being slow. I hope someone is able to help. Thank you for taking the time to read this!

Update: I just tried to open chrome, and the computer froze completely. It would not unfreeze. After leaving it frozen for a minute or two, the screen went black. This is becoming very frustrating.

(This is my original thread High CPU Usage "Interrupts" - CPUs - CPU-Components )

I recently built an i5 IB system involving a Z77 AsRock Extreme4, 3570K Samsung 830, 560Ti and my old RAM.

Well when I first set it up I didn't notice anything with the processor but that night I started noticing one core is at 70% constantly, and I've narrowed it down to 'atapi.sys' file. Which is the HDD Driver, which I have NO IDEA how to update. As you can see in the other thread I've followed basically every lead I've had but I'm just stumped at this point. Maybe it's the Windows disc I'm using? Or -maybe- the Primary IDE Controller thing will work. I'm kinda hoping someone has had this issue before and knows what causes it.

Welcome to TSF :)

The first thing that springs to mind after reading the other thread is that it could be the Intel RST drivers running interference here, you only need the standard Intel drivers from what I understand of your system, is there a way to change the options of the RST? Or an alternative Intel driver?

Task manager shows system interrupts running at 20-30% consistently which I suspect is the cause of poor performance generally with overall cpu frequently solidly on 100%. Have re-installed windows (now anniversary edition), run HP support assistant which recommended adding chipset, bluetooth and another driver and I have added them. Have tried disabling devices in device manager but can't find the device causing the problem, no problem devices showing. Everything runs fine, just slowly. Obviously I am aware that this laptop has a Celeron processor and not much memory so it is not going to break speed records but subjectively it is slower than a dual core Atom box I have. Hoping someone has an idea how to fix this. Thanks in advance, George

A:High interrupt levels

The combination of the Celeron processor and only 2 gigs of RAM is just not going to perform well enough to run Windows 10 with any kind of satisfaction. All you can do is go into task manager (ctrl-alt-delete) and startup and disable as much as you can. Go into advanced system setttings...visual effects...set for best performance. Then on the advanced tab set the paging file to a static size...with 2 gigs RAM set it for 2048 megs uncheck "automatically manage" and then set both the initial and maximum to 2048 megs and reboot....you could also experiment with a 4096 size and see if it is any better. What this will do is 2 things. Turns off all the eye candy in Windows 10 which takes processor cycles. The theme of the OS will now look like Windows 2000, very plain Jane. Also it will stop the resizing of virtual memory, which itself takes some of the processing power of which you have none to spare. Try these things and post back.

I'm having two weird problems, that may be related, or maybe not. Some background... I built this machine five years ago, and recently decided to upgrade to an SSD, and to clean things up by reloading Windows, getting all current AMD drivers, and loading only the apps I care about. The install went well, but as I began using it, I noticed that about once an hour, the active window would freeze, with the message "not responding" on the title bar. Windows was still alive, as I could bring focus to other windows, although sometimes a second window would freeze as well. My only recourse was to wait... 20, 30, sometimes 40 seconds... and then operation would return to normal.

Process Explorer reported that one of my CPU cores was constantly spending 60% or more of its time handling interrupts and DPCs. Interestingly, whenever a window was frozen, this process would drop to nearly zero.

I ran Windows Performance Analyzer, and saw that one CPU core was spending over 60% of its time on interrupts, except for exactly once per second, when CPU DPC usage would spike way up for a few dozen microseconds, coincidental with CPU interrupt usage dropping to zero.

Getting a summary table at the point of the DPC spike showed that almost all of it was due to Usbport.sys.

But the interesting part is that my Deferred Procedure Calls and Interrupt Service Routines causes the CPU usage to run at a constant 70-90%. The only way to return to normal is to do a restart.

Problem - 1 of my cpu cores in maxed out all the time.

Cause - Behringer Guitar-to-USB Interface

Details - When the device in question is connected to my pc, cpu core 1's usage goes to 100%. Not connected or disabled in device manager = Everything's fine. I checked my temps and they are staying steady at the usual idle temp of (42c). I checked task manager to see which process was to blame for the cpu usage. When none of them were, I opened resource manager only to discover that something called "System Interrupts - Deferred Procedure Calls and Interrupt Service Routines" was the culprit. I tried to google the issue and all I came up with was this PDF file(attached to post) that I couldn't make much sense of. Also, I'm using some ASIO ultra-low latency drivers for the device(not sure if that'll help).

If I leave the device plugged in will it cause harm to my pc?
Is there a way I can disable/enable the device with a shorcut/hotkey?
Is it possible to get this thing working properly?
 

A:Solved: System Interrupt CPU usage?

This sort of problem is almost always caused by incorrect drivers. Are they WHQL-certified? Are they the correct drivers for the OS version? If not, you can try other versions of the driver to see if that helps, or contact the manufacturer about developing certified drivers.

Hello everyone!
As the title says, I am getting a high interrupt value on my laptop. Using Process Explorer, it is indicated at usually somewhere between 10 and 12 cpu.
It started at the end of last summer, which was particularly hot, and might have caused it to overheat, although I am not sure that this is the cause.
I have already carefully opened it up to inspect the fan and other parts for dust, which was not there.
At the moment, it is causing the fan to make a lot of sound constantly, which is annoying, as well as not performing as well as I would like it to.
 
Also, what I've tried so far is to see if it depended on any recently installed drivers, so first I tried to just roll it back to an earlier point, which did not help. At that point I decided to wipe it clean entirely and reinstall windows which only process explorer installed, which didn't help either.
I have also tried updating all my drivers.
I am not really very knowledgeable when it comes to diagnostics, so any help is greatly appreciated.
 
Thanks in advance!

I have Norton AV running, as well as Windows Defender, and am immunized with Spybot S&D 1.3. Yesterday, following instructions on your forums, I went through my Control Panel - Add/Remove Programs(no suspicious programs), ran Ad-Aware, Counter Spy 2.0 Beta, Crap Cleaner, Norton AV and scanned for root kits, but can't find the problem. No spyware, malware, viruses, or trojans were detected. My knowledge & bag of tricks are exhausted. Can anyone help me before my computer blasts off for parts unknown. Also, when ccapp is running excessively, I can't download my e-mail via Outlook Express, but G-Mail works.I am enclosing 2 separate HJT logs: before & after running all the detection/cleanup programs. Help would be greatly appreciated.ThanksMikeylikesitLogfile of HijackThis v1.99.1Scan saved at 6:35:20 PM, on 11/28/2006Platform: Windows XP SP2 (WinNT 5.01.2600)MSIE: Internet Explorer v7.00 (7.00.5730.0011)Running processes:C:\WINDOWS\System32&#...

Don't understand since yesterday and now today my cpu mostly running at or around 100%. Yesterday, unit got so hot it crashed and I had to do a restore/fix. Right now I have 95 processes running. I have scanned for any malware/virus but nothing came up. I hear the fan running so I am assuming the cooling is not shut down. Any comments would be appreciated. Could it be my browser? Using Chrome. Yesterday there were about 30 files from MS download/installed. Today around another 15 files. What's going on here?

I have a serious problem with my computer, in tuesday of this week when i was playing a game my computer froze nothing i did worked, even after 5 minutes without issuing any order, so i decided to press the power button. When i restarted it there was a blue screen and the computer just started looping, safe mode didn't work(because when i pressed f8 a red screen would appear with a GRUB command line and some other option that didn't work) , system restore would just sit in a black screen with the mouse pointer, so i decided to use the cd the pc came with to restore it to the company configurations, but it just it would just sit again in a black screen with the mouse pointer. Then i downloaded Seagate Tools and managed to format the hdd, but after 45% it would just stop the format but it was enough so i could use the company cd to restore the system( I did this 3 times, making windows updates only at the third try). When i finnaly managed to restore it the computer worked perfectly so i decided to reboot it two to three times to see if the problem would happen again, it didn't but it started another problem, when booting the system would just load for 5 to 6 minutes, if not more, and then i was finally able to use it but my hdd ligh was solid so i went to the task manager, resource monitor and saw that svchost.exe was quite heavy on the system.

I disabled windows indexer because it was being used a lot, but still the problem continued. I decided to update ... Read more

Roughly 1 hour after rebooting, with nothing running besides MSN, xfire, and mozilla, my CPU utilization goes to 78-90% with no let down. AMD Phenom X4 9550 w/ 6gb ram, nvidia 9500, install is 2 days old. This is very disappointing because it means that even youtube videos hitch, and games get 2fps. Sad to say I had better performance in xp sp2 on a 3.2ghz P4 w/ 2gb ram and an ATI x800xt. Not counting games even. Although sadly SWG get roughly the same or worse performance, which is likely split between equal perf being poor engine on SWG (SOE)'s part, and the 2fps on Win 7 (when I launch after having been up for 1 hour or more). I've shut down obviously non-essential services (anything HP installed, my media sharing services) and used msconfig to take out services that aren't MS provided. Even Vista provided better performance, although I still had hitching on youtube videos (i've got high speed cable 3whatever and get downloads at 500+k/sec). Any ideas? This is very disappointing. I would rather get the benefits of Win 7 but I'm at the point where I'll install XP on this new pc. And I'm leaving out UI problems I have w/ Win7. Any tips are appreciated. I've done malware scans as well and dont have a virus scan running realtime (unless it's built into Win7).
Thank you for reading this, and ty in advance for any suggestions.
