I'm having a problem with my Core 2 Duo E4500. It is constantly running at 100% or thats what task manager says anyways while the processes only amount to 20% at most.

Anyone know what could the problem be? Could it be a virus or is task manager just reading it wrong?

I'm on vista btw ughh

It's running ok in normal use but I tried playing a game and found it very jaggy. I downloaded process explorer and found a fahcore_a0.exe was taking up ~48% and another fahcore_78.exe taking up another ~45% what are these

And your CPU usage is back to normal? Sorry for asking more questions. I'm just trying to make sure your thread will be useful to people who have similar problems.

Google is your friend.

It's a distributed computing project sponsored by Stanford University. If you don't know what it is, I don't know how it got installed on your system. Check to see if you have any FAH software in the "Add/Remove Programs". If not, here's some instructions I also found by doing a simple Google search for "fahcore_78.exe".

Yeah, I went to the overclockers forum section, and one guy said to kill "FAH502-Console.exe" I couldn't find that, what do I do? I put all of the FAH things to manual, but it still says my CPU is running at 100%
