weird very high cpu usage issue on this emachine pc...

[tgg]

Ok I have a issue here That I need help troubleshooting. I am a pc tech got my own mobile/onsite business and I have a customers emachine t3604 tower here and what happen about a week ago he called me because during boot up it was giving a MBR error. So I said since his pc was running slow and sluggish already rather than attempting to fix the error, i'll just format and reinstall windows. Well to make a long story short that wouldnt work I determend that the Sata harddrive was bad, so I put in a new one and was acting strange also, so I change cables, even tried regular IDE drive and same wierd issue. Sometimes it would go on through the installition process of either vista or xp but it was slow, sluggish, just strange and sometimes it would just give a generic no boot drive detected during the POST.

So I was thinking maybe its the motherboard because i wouldnt be suprised since I see motherboards go out during my business all the time specially these days with these pc's, they are not built the same like they use to, I still got old compaq, dells, hp's etc towers here that are still going like 5-10 years with same original hardware.
Ohh forgot to mention with these issues going on couple times i did let it install a fresh copy of windows but it was acting slow, sluggish, at the desktop and I went to task manager and notice that the reason why its been acting like this is that the CPU resources are being used constant full throttle basically, it goes up and down from 60% to 100%.

So I never have experience this type of issue before, so I gave it back to the customer klike this it was still useful the customer dodnt complain he said it wass faster than we they had it working before. But today I picked it up and it got worst, it was actual stuck at full throttle 100% CPU usage when looking in the task mangaer.

So I'm thinking theres something up with the motherboard. What do you guys thing?

Thanks...

if the temps are too high could the chip be throttling down in speed, download a program like core temp on google and try to see what your temps are??? Sounds like malware except you said you reformated.

Yea its not a infection issue, lloks like some type of hardware issue. Hmm if it is a temp issue wha maybe reaplly the heat sink with fresh compound or what? Seems like the fan still moves though it does sound very quite, I'll look at it again.....

I have no clue, but I think the problem is that it's an eMachine! My mom got one 6-7 years ago and I don't think the thing has a single heatsink not fallen off from the mobo.
