Internet shuts down suddenly, at times won't.

Q: Internet shuts down suddenly, at times won't.

My PC is an XP Home, service pack 2.
My internet has been acting strangely lately. Sometimes it comes up with a white page or takes a couple of trys, also difficult to close at times.
These messages are now showing and the pages closes down even when I try to debug, also it closes down immediately at times when I click on something and sometimes I can't type on the search line.

dbgheap.c, line 1132, debug errorm debug assertion failed, breakpoint.

I have disabled 3rd party browser extensions, and have took off Google as my search engine.
I'm clean of malware or viruses.

Go easy on explaining to me, I'm a senior and a little slower then I'd like to be at times understanding.
Thank you.

Preferred Solution: Internet shuts down suddenly, at times won't.

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.)

Hi .

What browser? What version?

You realize that not having SP3 installed...makes your system more vulnerable to malware....than it would be if you had SP3 installed?

I have a perplexing issue.

The internet at a clients office, they lose their internet at exactly 4:30pm, and they get it back at exactly 4:45pm

I already checked the router, not only is the time restriction not set, it doesn't even exist, there is also no third party firewall. I would normally suspect virus, but this is odd behavior that i've never seen a virus do.

Any thoughts?

EDIT: Malwarebytes reports no infection

A:Internet shuts off at set times consistantly

Exactly what happens?

What is the frequency..."consistently" is pretty vague, IMO.

How many systems are involved?

If others...do they lose connectivity?

Anyone consult the ISP?

I'm having an unusual problem with my computer. At random intervals I will lose my connection to the internet for several minutes. Then it will come back like nothing happened.
When this happens, the Windows Network & Sharing Center shows that my connection is fine, and when I run troubleshooters they don't find any problems, even though I can't get online. It's not the browser; I try both Firefox and Chrome, but neither will work when this issue crops up.
Some days it doesn't happen at all, and some days it happens several times in one day.
My computer is running Windows 7, and I am using a wired connection (ethernet cable) to connect to my router. There are three other computers on the same network, connected to the same router (one wired, two wireless), and they don't have this problem. I got this computer a few months ago to replace an old one, and the old one (connected with the same cable to the same router) didn't have this problem either.
Does anyone have any idea what could be causing this?
Thanks in advance!

A:Suddenly lose internet connection at random times

to Bleeping Computer Community sjnew

At random intervals I will lose my connection to the internet for several minutes.
My computer is running Windows 7, and I am using a wired connection (ethernet cable) to connect to my router.

The first thing to verify is if you loose internet connection is check the LAN port (led light) of the router from where your computer is connected. Or vice-versa, the LAN or Ethernet port of your desktop. There are signal lights indicator showing that it is connected (illuminating) or none if not. Try a different cable or reseat properly just in case also as a test.

Well first of all, i got it up and running after about 2 years of sitting. Cleaned it out of dust, made sure everything was plugged in and pushed in. It ran for couple days, playing games internet etc. Than i brought it home and i re-did it like it had this OS that was windows 7/vista/XP and i made it XP. It worked and ran fine (its 32-bit btw) and than i had plans so i shut it off probably by holding power button i forget. and I just got this ram for my pc PC133, (its double sided, and says samsung on it ye my computer isn't samsung its Seanix) i got 2 512mb sticks. My computer has 3 slots for ram, already had 2 (1 is 256mb and other not sure i think 512mb) and so i put one of the new sticks in last slot, i try starting, and it starts and than shuts down. Not sure why i hadnt got it in properly because i just realized today i had it wrong way lol but i turned on shut off. So i removed it and ried turning on, nothing, wouldn't start anything but it did have a L.E.D light up when its off showing it gets power and same for the ethernet cord had the 2 lights on. but than i took out power cord put back it moved and pushed some things and turns on and loads up. Than i shut off and turn back on and it starts to Beep 3 times. i googled and check says if 1 long and 2 short video card or if 3 short its the ram.

Whenecer I am working on IE, it sometimes shuts down. A send error and don't send error comes up if I close out of a pop-up or something (though thank you Windows Firewall for pop-up blocking). What is the cause of this and is there anyway that I can keep it from happening? Also, it takes a lonk time to load even though it is just a homepage (http://www.optonline.net/Home ). Is there someway that I can speed this up?

A:My IE Shuts Down at Wierd Times...

A couple of things to try...

On the message window of send or don't send, click on the details and look to see if you can follow the links and investigate the problem and any suggestions for correcting.

You could also try going to Add/Remove programs-->Windows components-->uncheck Internet Explorer as though you were going to remove it and a option to repair IE along with remove. Try the repair option.

My PC just goes off as though the power has been cut-off and then restarts again. It is worse if I'm also talking on MSN or Skype, it will even do it with no programmes running.

It has done this more or less from the moment I bought it, I know very little about the workings of a PC and would be gratefull if someone could suggest a possible cause and solution.

Hi there @Bwriter,  Thank you for joining in on the HP Support Forums and Welcome! This is a great place to ask questions, find solutions and get help from others in the community! I read your post on the HP Support Forums. I wanted to reach out to you and help! I understand that your HP Pavilion Notebook PC is randomly shutting down on you.  I am going to provide you with troubleshooting steps even though at this point I do not have which Operating System you are using. The steps could still help you resolve the issue.  Did you receive any error messages?Do you have any beep codes or blinking LED lights? How long has this been happening for?Have you done a BIOS reset?Do you have the Notebook ventilated? What do you sit your Notebook on when you are using it?Is the fan noise louder or constantly spinning?Have you done any updates using Windows Updates or the HP Support Assistant? Updating your Notebook computer including the BIOS has been the solution for some, stopping apps from starting when the Notebook powers on for others.

Hi guys,

A couple of times my PC suddenly shuts down while I'm working on it. And I immediately switch the power off and then turn it on again after a couplea minutes and then it'll go to the black screen with the option "Start Windows Normally" which I always choose and everything is ok and all but then in a couplea days it happens again.

This has been going on for quite sometime as everytime it happens, I get really nervous coz i dont know the cause of the problem.

Would really appreciate your expert advice on to wat may be causing this sudden shut down and is it causing harm to my PC and how i can prevent it and all.

I'm using Win XP.

This problem started a week ago.

When the pc shut down i can`t turn it on right away (nothing happens), so i have to unplug the power cord for about 10 secs to turn it back

i thought the problem was processor overheated, so i bought termal paste, now temps are good, arround 39C IDLE and 55 under heavy load.

so, i don`t know why my pc keep shutting down suddenly.

(i have pc specs in my sing, if you do need any other info just let me know)

Hi there everybody. Lately I've built up my own computer. I am kind of expert so there shouldn't be any nab problem like mounting something wrong or placing wrong cables in wrong places but I have this problem. My pc runs very smoothly and powerful but after a period of gaming (like 1 hour of gtaV) my pc suddenly shuts down. It gives me no warning at all. I checked the temps and they all seems to be normal when the power off happens, so I think it couldn't be an over heating problem. This happens only when I "make things hard" let's say. The first days that this happened the AI software told me there was low voltage but now that doesn't happen anymore. But that's strange assuming I have a KCAS 600w.

My specs:
Mother: ASUS M5A99FX PRO R2.0
cpu: AMD FX 8320E 3.2->5GHz 8 core
Ram: 4GbKingstone+8GbKingstone
PSU: KCAS 600w
Cooling: Freezer 7 Pro rev 2

Help please, that's my struggle since 7 months

A:PC suddenly shuts down

I kept it monitored until the shutdown and on the AI software I saw that there was low voltage on the 2v and the 12 one.

My PC shuts down all of a sudden all the time(Up to like 5 times now). There's no warning, and no blue screen. It just shuts down and then starts back up again instantly.

Also, i have gotten 2 Blue Screen errors, and 1 incident where the lsass.exe process terminated suddenly and started the "shutdown -s -t 60 -c"Dont remember the message"" command at the login screen. All within 2 hours.
And right now my computer just lost all sound, which means its probbably about to shut down again.

I restored my computer 2 days ago, and havent installed much since then. It was suggested that one of my 3 RAM sticks had gone bad. But when i opened my PC, i couldnt figure out how to take the RAM sticks out.

Why is it doing this?

I've been experiencing crazy long boot times recently. I've always had this problem to a certain extent, but it's getting way worse now. When I first got this and until a couple weeks ago, it had been rising from about 60-70 seconds to a minute and a half and up to two. Suddenly, today it skyrocketed to 270 seconds - almost 5 minutes. I rebooted 3 times and all of them took upwards of 200 seconds. I have no idea what is going on, as the only event log I have without code 100 is for a program that took 4 extra seconds to start. I'm leaving the details below, and I can see that prefetch, explorer, and the postboot times seem to be the culprits, but I'm not sure how to deal with that, especially since my previous 2 reboots yielded results different to both this one and each-other. I have a quad-core AMD FX-4100 running at 4.1 GHz and 8 gigs of ram, so I don't think it's a hardware issue. I do have an HDD so I expect slower boot times than brand-new SSDs, but this is ridiculous. I do have quite a bit of files in it, but it's relatively defragmented and I have trouble believing that's the reason for it taking almost 5 minutes to boot. Any help would be greatly appreciated, and I'd like to avoid formatting as much as possible, as it would take forever to back up all my files.

Hello everyone,

I hope there is a saint in here who can help me solve my problem.

I have had my computer for a few months and it has had no problems for the most part. However, I woke up this morning to it not loading multiple websites. It seems to load approximately half of all websites perfectly fine. The others, it will time out on. It is consistent which websites it loads and which it does not. For example, Gmail, Facebook, and Blackboard are working as normal, while Yahoo!, ESPN, a number of other sites do not.

Here are the facts:
Has been occurring for one day.
Some websites load, some do not.
The websites that load or don't do so consistently.
It is also consistent across both Chrome and Firefox.
Deleting cookies did not solve the problem.
Restarting the computer and the router did not solve the problem.
The problem does NOT occur on a similar but older (and Windows 7) computer I am using to type this.
I ran a McAfee virus check that turned up nothing.
All websites that don't work say "Connection Timed Out"

I am grateful for any help that can be offered. Thank you.

~Mayhem, Electric.

A:Suddenly Not Loading Many Websites (times out)

If McAfee itself is not the problem (try turning it off) there are few more things you can try:

netsh int ip reset
netsh winsock reset catalog

We have Win7 Home Premium on a Compaq CQ2014...AMD E300, Radeon graphics, 3gb RAM, 500gb HDD, Realtek HD audio. About 3.5 yrs old, faithfully updated, but I'm sure there are other, largely hidden issues I don't know about, or would take much too long to find out.

Antivirus is MSSE, and I also have Malwarebytes products (needed their rootkit one just the other day when some **** dumped something in our application data folder)

Lately there are times of the day, mostly late at night around 11pm to 12mid, when it gets nearly to the end of shutdown, then stops. No disk activity at all. (Turned verbose on, it says "shutting down" when this happens.) If the power is shut off manually at said point, there are no visible problems if/when it is restarted in the morning.

Should I look into, say, M'soft SDK for a trace?

Thanks for anything you can suggest/provide.

When I try to install Windows XP onto my computer, my computer shuts down. I'm pretty sure I have enough power, as I am using a Intel i3 and the only other things that require power are my CD Drive and my Graphics card (NVidia GeForce 210, which can be seen here http://www.compusa.com/applications/SearchTools/item-details.asp?EdpNo=5271085&CatId=28). They are all low profile things, and I am running on a 300 watt power supply. All fans are spinning, and I connected everything correctly. No noises happen when it shuts down, it just does it.Do I have to buy a new PSU?

A:Computer Shuts Off Multiple Times

A 300w power supply would not be considered enough power. It may be tht you need a new power supply. More along the lines of a quality manufacturer 450 or 500 watt power supply. Corsair, OCZ, Thermaltake, Enermax, Seasonic, PC Power and Cooling are quality manufacturers among a few others.

Intel Pentium 4 3.0 GHz
Two Corsair ValueSelect 256 MB DDR400

It's running a fresh install of Windows XP Home. At random times, it will shut off by itself with no error message -- sometimes after an hour, sometimes after a day or two, sometimes with applications running, sometimes with nothing running. It boots back up fine and has no other issues. All drivers and BIOS are latest and nothing is flagged in the hardware manager.

The ASUS PC Probe reports CPU temperatures no higher than 53 C, even under continuous heavy load, and all voltages stay very close to spec (within 0.3 V).

Any ideas?

Forgot to mention

I forgot to mention that the Intel Pentium 4 630 didn't come with any thermal paste, so I didn't apply that below the stock heatsink.

Is that an issue?

Would the ASUS Probe report a false heat score and the CPU actually be considerably hotter?

I've been struggling with this for months and am at my wit's end. Any help anyone could offer would be greatly appreciated!

Basically, without warning, my computer, for no apparent reason, shuts itself off. No shut down. It simply shuts off, as though the power had been disconnected. (It might be worth noting that on starting it back up again, chkdsk doesn't run.)

At first, I though it was a random occurence and likely a hardware problem; possibly the Power Supply. However, my MoBo is set to power up the computer after losing power and, after one of these unexpected power downs, the computer doesn't start back up until I hit the power button.

I've also started to notice a link to downloading. Namely, if there's multiple downloads going on, it seems to trigger the problem. It shuts down almost every night, which is when I've got utorrent scheduled to run, and I've been able to trigger the problem reliably by initiating multiple downloads of podcasts in iTunes. It also seems to happen sometimes when web pages are taking too long to load.

It's probably important to note that the computer functions perfectly otherwise. I can tax the system with the latest games or a heavy set of video transcodes without incident, so I'd have a hard time believing it would be a heat problem.

Hi Everyone,

Computers never cease to amaze me. Just when I think that the computer is running "the way it should be", the damn thing restarts on me. It happened a few days ago while playing Madden 2003. It happened this morning, while printing a picture, I decided to close Paint Shop Pro. For some reason, I am leaning towards this being a video card problem. More specifically, I think there is a conflict between the video card driver and several programs on the computer (i.e. graphic intensive). It has always been my understanding that a computer is SUPPOSED to remain ON until you tell it to TURN OFF. I hope someone on this amazing board can HELP ME OUT!!

Thanks In Advance,

I'm assuming that you've confirmed that your CPU fan is working properly? (in case it's overheating)

Check out this site....if you don't have this driver, then try downloading and installing it:


I know that the specific error they mention doesn't really apply to you, but it might help your problem.

You could also disable your computer from automatically restarting with system errors. Right-click on My Computer, go to Properties, then Advanced, then Settings (under Startup and Recovery), then take the checkmark off "Automatically Reboot". This is probably what's causing it to reboot....while you're working on something that deals with graphics, and the system generates an error, it automatically reboots.

These are just a couple of suggestions.

My Spectre x2 keeps turning off automatically without warning, even when I'm just watching YouTube videos or using Facebook. There's nothing to signal that it's going to happen, it just goes to a black screen.

I've been struggling with this for months and am at my wit's end. Any help anyone could offer would be greatly appreciated!

Basically, without warning, my computer, for no apparent reason, shuts itself off. No shut down. It simply shuts off, as though the power had been disconnected. (It might be worth noting that on starting it back up again, chkdsk doesn't run.)

At first, I thought it was a random occurence and likely a hardware problem; possibly the Power Supply. However, my MoBo is set to power up the computer after losing power and, after one of these unexpected power downs, the computer doesn't start back up until I hit the power button.

I've also started to notice a link to downloading. Namely, if there's multiple downloads going on, it seems to trigger the problem. It shuts down almost every night, which is when I've got utorrent scheduled to run, and I've been able to trigger the problem reliably by initiating multiple downloads of podcasts in iTunes. It also seems to happen sometimes when web pages are taking too long to load.

It's probably important to note that the computer functions perfectly otherwise. I can tax the system with the latest games or a heavy set of video transcodes without incident, so I'd have a hard time believing it would be a heat problem.

Based on suggestions from others, I have tried replacing the RAM and Network Card, but neither has had any impact on the problem.

A:PC Shuts down suddenly without warning

I'm not an expert by any means, but I guess there's no harm in having a bit of (possibly helpful) input...

It could have something to do with a faulty hard drive...I had something not so long ago where I had a lot of damaged secotrs, and copying things between disks would restart my computer (and sometimes never let it start back up)...

Have you got a spare drive you could test? Or if you have multiple drives, set the other 'good' one to the default download location and try to induce the problem.

I dont know what anyone else thinks of this...it could be completely wrong, but I guess there's no harm in trying!

Hello All,

I will appreciate if you can help me solve this problem.
I noticed that whenever I type the word antivirus, mcafee, antispyware in Internet Explorer or Mozilla Google search, it closes the windows automatically.
The McAfee antivirus is not responding, it is not even let me uninstall it.
I got to ran the HJTInstall.exe and I am attaching the logs, so with your expertise you can give me more light on how to troubleshoot this issue.

Thanks in advance.

I am running windows 7 on this laptop which I bought back in April 2010. Just 30 minutes ago, my laptop suddenly shutdown without warning or whatsoever, and upon rebooting, it hung while loading windows. I tried running startup repair but nothing was found. I restarted another time and managed to get into Windows 7.

Could it be a failing motherboard?

Thanks for responses.

Hey guys,

I have a serious problem. I bought a new computer lately, it is superb but it has one error. Everytime i start my computer it shuts off after an undifined amount of time. It doesn't cleanly shuts down windows or something it just roughly shuts off. I did run a memory check, i build in another cooler for my processor and it didn't change anything. Sometimes it happens when i'm gaming, sometimes it happens when i don't do anything so it is a hard problem to analyse. When i am in safe mode it doesn't shut off.

These are my specs:

Amd Athlon 64 X2 dual core 6000+
2 GB memory
450W power source
Asus 8800GS graphic card

I hope you can help me!

I would make sure your drivers are up to date and try a system restore if you have a restore point. Also, you might be able to find our more about whats causing it by looking at the event manager for dump files. Otherwise if its not a big hastle for ya i would consider a reinstall.

my HP Paviliion 22z was one month old. I was using it and all of a sudden it shuts off. no warning message. I thought it's a power cord connection problem. but after I look carefully, no connection issue. I pressed the power button, it started and everything looked ok. However, this happens more and more often. It is less than 2 months old, as of today. no sign of slowing down or any problem using it. it just shuts down right away. looks like there is a power failure. but when i press the power button, it turns on and works just fine. lost the data I worked on. Very annoying. Anyway to fix it?

Greetings-- my previous problem was wonderfully solved here, so am hoping help with new problem will be successful.

This past week I've suddenly developed a problem where without any warning the computer will shut off. The 'power' button on the PCU will go to an amber, and will not respond to repeated pressings. The only way I'm able to get it back on again is to cut the machine off at the power strip, then press the power button. I've run some various system scans, and nothing turns up.

I am using Windows XP, have a Gateway computer, and have NO CLUE about what is going on. Many thanks for your thoughts and suggestions. Please let me know what more information I need to provide for consideration.


A:Computer Suddenly Shuts Down

Hi there!

Before I can help you in any way, I would like you to give information on your computer, such as service packs are installed or not, do you get any error messages, have you been experiencing speed problems with the pc lately, or have you been fiddling with the registry( ). Thank you!
Looking forward to helping you!

Lately, my computer has been shutting itself off suddenly, followed by a loud high-pitched constant tone, which lasts until I turn the power off on the power supply. When I turn the computer back on, I get a blue screen that says there was an error and the system has been shut down. If I leave it off for about 10 minutes and turn it back on, it will come on fine, but eventually shut off again. A friend of mine mentioned that this may be a motherboard issue, so I'm just wondering what everyone here thinks.

I was recently having issues with the LCD backlight on my Dell XPS M1530 laptop. So I took it to the tech guy who fixed the backlight issue. But, now I get sudden shut downs while I'm working on my laptop. The screen goes white for a second before it shuts off by itself. Could it be an issue with wiring inside which the tech guy messed up? Or maybe the heat? because I notice the shut down when mostly my laptop is resting on a wooden table for about half and hour. Any advise?

Does your laptop have the Nvidia GeForce 8600M GT installed? If so your problems are very likely a result of the nVidia Defect (I have recently had a refund on a laptop I boughgt in 2007 because of this), have a look here http://www.nvidiadefect.com/ for info, it's a very helpful website.

Heres my problem:
When i start outlook and i hit F5 to check for mail, i get three spam emails (always the same ones) and then i get the message:

"microsoft windows ™ messaging subsystem spooler has encountered a problem..." etc

I guess thats the MAPISP32.exe thats necessary for sending and recieving email. So guess what happens, i cant recieve or send email. The only thing I know that I changed in the computer is that i recently disabled and then enabled again the system restore. I also recently installed SpywareBlaster. Can anybody help me?

Thanks in advance.

PS: I run WinXP and MS Oulook 97.

You may have a corrupt mail spool. Call your isp and ask them if they can delete those first 3 spam messages and then see if it works.

Sometimes my laptop suddenly shuts itself down, as if id just cut the power.

This usually happens while playing Crysis, is my computer getting to hot?
Im currently using WinXP, and it happens all the time, after about 20 minutes gaming. I used to run Windows Vista, and it happened only twice in 5 months. Anything I can do?

A:My laptop suddenly shuts itself down

My first question to you is this: do you notice any intense heat coming from the underside of the computer? Try playing the game in your lap, and feeling for heat (don't get yourself burned though!).

Also, what type of laptop do you have? (brand and model #)

In the past Sony Laptops were very known for overheating.

I'm from India. I bought a HP 15-ay106ne laptop through my uncle in Abu Dubai on 01-01-2017.After a week I noticed that it didn't charge to 100% it reaches 99% only. After 15 days I noticed that it suddenly shuts down when the charging reaches 15% without any notification about plug-in. After few days it shuts down in between 15% and 20%.Now it's shutting down in between 36%-40% of charging. I found that the battery backup is also not good. Original backup is 10 hours but my laptop gives 5 hours of battery backup.I gave my laptop in to a HP service centre and they said it has a hardware problem. In India the spare parts are not available so please go to Dubai with your laptop.I preferred to buy it in Dubai because of its international warranty. But now they are not going to help me out of this problem.Please help me to get my laptop in good condition. And suggest me how to decrease the cycle count.

My other computer suddenly shut down while i was playing a game. Then i smelled a burning odor. I tried turning on the computer again but it wouldnt turn on so i opened the case and felt the hardwares. The power supply and the harddrive were hot.

What happened to my computer? how do i fix this?


A:Computer suddenly shuts down...

have a look and see if you can see anything burnt on the motheboard.
powersupplies and HD are HOT - how hot - remember they do run very hot hence the fans.

when you turn on - do any fans spin up or lights come on - if not its likely to be the PSU.

you could try disconnecting the PSU from the MoBo and other devices and then switch on and see if fan in psu runs.

otherwise you probably need a meter to check if the psu is working.

whats the make/model of the PC and then maybe someone can advise more on parts etc.

Hey Techspot, I'm hoping you can help me out with a little problem I've started experiencing. I got a Lenovo G555 just last year, and everything's been going great with it so far. However, as of about a day ago it decides to start shutting down without any warning whatsoever. It seems that this happens at random also. Some times I can keep the laptop on overnight (I like to have videos playing while I sleep) with no problems, and other times it snaps off after not even 5 minutes. Thus I can't really finish a scan with avast! or malwarebites. I haven't done anything out of the ordinary either. I don't know if it's really overheating because I keep it in a similar environment as my Toshiba laptop that has remained on around the same amount of time with no overheating whatsoever. I'm running Windows 7 on my Lenovo.

EDIT: I thought that my problem was in fact overheating, so I cleaned the fan area with some compressed air. That seems to help a little bit, but my computer still has a tendency to shut down randomly, just a lot less frequently. I checked the temperature with SpeedFan, and upon startup my core temp is as high as 80C, then cools off to about 60C when I'm doing nothing. The thing that worries me is that SpeedFan can detect no RPMs from my fan. Fan1, Fan2, and Fan3 all show 0 RPMs in the program.
