100% CPU Usage

August 31, 2011 at 04:00:42
Specs: Windows Vista Service Pack 2, Core 2 Quad 3.2GHz / 4gigs
Recently this week,this problem started..my screen went black,then when i restarted,it was fine until a few minutes,it went blue,I restarted again,then it ran like normal and after a few hours it was on 100% cpu usage,then the screen went pink,this occured several times and several colours like green,black,white,pink,etc. covered my screen,the computer was iresponsive,hangs,and only usable half an hour after startup before it goes to 100% cpu usage again.
It even came to a point where I couldn't start the computer and had to run startup repair,it came out clean[said there was no problem],I scanned it and there wasn't any virus,so I thought it had hard drive issues,so I restarted in safe mode and ran error checking on the hard drive,came out clean too,please help...

Sounds like an overheating problem. Is it a desktop or laptop? If it's a desktop, pull the side cover off ( unplug it of course ) and use a can of compressed air to blow out the dust on all the fans etc. Do you have a graphics card or onboard video?

Sounds like it. Also run Malwarebytes if the CPU usage remains high.

You have to be a little bit crazy to keep you from going insane.

Open Task Manager, select the Processes tab, on the

File Options View Help menu...

Click View > Select Columns, Add in PID, CPU Time, Memory Usage Delta, Peak Memory Usage columns.

Still while on the Processes Tab, Under "Image Name" column - look over to CPU Time and High Memory columns to see which files may be causing high usage.

You may have to use Process Explorer :
http://technet.microsoft.com/en-us/...
...to determine what some of the generic Windows Process names running are associated with software on your PC.

I've seen HP printer software, TouchPad (laptop) software and others cause high usage.

Still could be Malware running too. I'd run Emsisoft Anti malware and maybe an Anti-Root kit or two (like GMER, Radix, TrendMicro Rootkit buster etc) as well to see if anything is still on there.

MOOOOooove! OH and you're welcome!

Run Malwarebytes again but this time in Safe Mode.

Run msconfig and go to start tab, uncheck everything that is not Microsoft or your anitvirus program, Apply and restart the machine and see if that helps.

As noted above Process Explorer by Microsoft is a good tool to evaluate processes and understand what is running on your system. IF you try really hard you can get 'system idle' over 95% on a purchased machine and 100% on a custom machine. On my daughter's laptop I found an HP tool running that monitors a network for network printers' addresses which she had no need for, now her machine now runs faster and has better battery life (shut off service).
