CPU spikes to 100% randomly and stays there thus crippling my computer
About 30-100 minutes from startup, the CPU usage jumps to 100% and stays there until other applications start crashing or I lose patience and restart the computer. Even after I turn off all non-Windows-critical processes, the CPU still stays at 100%.
I've updated and ran Kaspersky anti-virus, Spybot Search and Destroy, and Lavasoft Adaware. As expected, all came back clean. I'm fairly certain it is not a virus/trojan/adware problem. Now, next thing on my head was an overheated CPU. It is winter season and my room has been kind of warm. So I checked the CPU right after restart in the BIOS - 42 degrees Celsius. That seems fine to me. So now I'm at a loss. I'm willing to try everything besides reformatting this HD because that'd be a pain in the arse :( OS: Windows XP SP2 CPU: AMD Athlon 3000+ RAM: 1024 MB |
If you're running 2000/XP, take a screenshot of Task Manager and post that for us.
Also run HijackThis. |
You see, right now it is behaving - there are no problems. But the next time it happens I'll definitely screenshot it. I do have a HiJackThis log.

Go to Windows Explorer, right-click and select properties for all your drives, and uncheck the box that says "Allow Indexing Service to index this disk for fast file searching".
|
I've turned off the indexing service for both of my hard drives.
For the record, during normal operation my memory/CPU graphs look like this: Normal:
When the computer starts misbehaving, I'll printscreen that and update the thread. |
are you sure fan on your pc working?
|
maybe dumprep? I totally cannot find ways to express my hate for dumprep.

have you tried killing the process?
and is Dragan your user name? |
If you wanna see about testing your RAM, then give this a go. Leave it running for 20 minutes at the least, and see if it throws up any problems.

how much time loading for boot,when show WinXP bar?

Domino - I've ran memtest for about three or four hours and it came up with nothing.
RYU - It takes me a bit longer to start up and shutdown nowadays. I've been experiencing this far too much lately and I'm thinking of reformatting my HD. There's damn nothing I haven't tried :( Just for kicks though, it happened again a couple of minutes ago and I went into Process Explorer. None of the normal tasks are using up the CPU time. This is what's happening: DPCs going nuts:
Apparently Deferred Procedure Calls are taking up 100% of the CPU. This is the cause of my problem and I have no clue how to approach the beast. If anyone has a suggestion, post it here in the next couple of days but otherwise, I'm formatting. :( |
Personally I would open the case and MAKE SURE the fan is working before you reformat.
If you have run Spybot, Ad-Aware, and by the looks of your 20 processes in Windows being fine, I just really don't see this being a software issue. Sounds like your hardware is overheating. If your computer has multiple fans, the issue could be with ONE of the fans not working properly. This of course is just a suggestion, I have no idea what "Apparently Deferred Procedure Calls" means, but there is always the possibility of a hardware error causing a problem that Windows can pick up. |
Some information here may be helpful:
http://forums.pcper.com/showthread.php?t=425589 In this case, it was a combination of video card drivers + GPU. Did you change your hardware configuration before the problems started? |
Haha, holy shit Blah I want to make sweet, sweet <3 to you.
I have the exact same hardware set and now I'm thinking that the problem is with my 6800GS overheating. Hm, gonna have to look further into this stuff. I might not have to reformat after all. |

try this:
1.open case pc. 2.try to remove all cards installed like"sound,network..." except VGA. 3-turn on you pc without put case.to if fans working will or not(power supply,processor and other fans if installed) 4-try to touch VGA card if hot or not. 4. after WinXP started open Device Manager. 2. Double-click IDE ATA/ATAPI Controllers to display the list of controllers and channels. 3-set none (if available) for both. 4-apply reg file I uploaded. 5-restart you pc and tell me if still slow or not. |
You work for a customer service hotline, don't you RYU?
|
Stop trolling.
If what RYU posted didn't work. Check and see if its svchost.exe under Local Service is spiking your computer. If that's what it is, just clean unwanted startups with HiJackThis. Clears it up for me whenever I had the problem. |

I also like how you need a time machine to follow the instructions in the correct order:
1-2-3-4-4-2-3-4-5 :tpg: Or you have to carry them out simultaniously: Remove all cards from the PC and use the device manager at the same time. |

All that registry file does is disable prefetching, so I would definitely suggest that #4 be completed immediately!!!111

I'm getting the impression that RYU is always just throwing together random bits and pieces of Google search results for some keywords (like "CPU" and "spike" in this case) through copy & paste without paying attention to the thread and the specific problem at all.
I understand he's trying to be helpful, but in fact, he just continues being counterproductive. |
