High CPU usage for no reason

[carlweathers]

Hello,

After installing my new heatsink I have started to get high CPU usage for no reason. No processes in particular are causing this, and I have formatted various times trying both vista and windows 7. It's not the hard drive, and it doesn't seem to be the RAM. It worked perfectly on XP with my old heatsink, so i'm starting to think it might be a motherboard problem. Any ideas?

Thanks,

Owen

My specs are: XFX x fifty eight motherboard
i7

It might be SIP
A processer can never not do anything. so it has system idle process.

Most computers dont show it but for some reason yours may??
I'm proberlyy wrong just wanted to try

Hope i helped

XP - I assume you have the Task Manager open, Process tab, and CPU sorted. Look at the process. Next to rule-out Windows run MSCONFIG and select Diagnostic and reboot.

7 - Task Manager Performance tab, what %. Next, ditto to rule-out Windows run MSCONFIG and select Diagnostic and reboot.

If the problem remains then it might be a temperature issue. Use HW Monitor - http://www.cpuid.com/softwares/hwmonitor.html anything >50C not under load suggests a problem.
