Solved 100% CPU Usage!

  • 0

Well….. my cpu usage goes up to 100% whenever I open anything, explorer or fire fox or when I try to install a program

that’s my pc

Processor : Inter(R) Pentium(R) 4 CPU 3.00GHz 3.00 GHz
Installed memory : 4.00 GB
Display adapter : Nvidia Geforce 8400 GS

I tried the next. but didn’t succeed to solve the problem:

1- performed an virus scan using kaspersky and Avira.
2- performed spyware scan using spyware doctor.
3- performed malware scan using Malwarebytes Anti-Malware.
4- reinstalled the OS several times ( tried windows seven ultimate 64 and 32 bit and windows xp sp3 32 bit ).
5- formatted my hard disk then installed a fresh copy of windows.
6- checked the CPU temperature and made sure it’s fine.
7- tried removing one of my 2 rams.
8- tried working with the build-in VGA card instead of the nvidia one.
9- tried restoring the BIOS default setting.
10- even tried changing the processor itself ( but with an older one ).
11- and of course tried to see which progress sucks up the cpu usage, and the result is that every program I open gets 90 to 100 % of the cpu usage!

and yet I couldn’t solve this problem.

wonder if any of u can help me

thanks in advance

  1. Thanks to all of you guys for helping me solving my problem.
    Actually the problem is in my processor, I tried my friend’s processor ( dual core 2.7 )
    and everything worked great, so now I’m pretty sure it’s my processor.

    Again thanks to all of u for your help, and sorry for taking me so long to reply, I’ve been busy.
