i have a core 2 duo @ 2.66ghz
running on a gigabyte mobo
an evga gtx 470 vid card
a 850w continuous power Antec p.s. (called CP850)
and my antec case with some godly amount of fans
i used to be able to overclock my cpu to 3.0ghz from 2.66
it won't let me even get as far as 2.8 without blue screening a couple minutes in, or restarting instantly at bios when i press save settings.. and converting back to default automatically
This never used to be a problem..
could the cooling paste i used on the cpu be going bad or something?
i have no idea what the problem could be, it's the same motherboard and processor i was using before
I have the same paste on since i originally installed the cpu way back when..
maybe 2 + years ago
the temps never get too high on the cpu but the cpu usage when i play a game or watch a movie sometimes sticks at or on 100% which doesn't make much sense to me..
like it's struggling to even play a game.. which i personally always believed was more video card related than anything else.
best practice is to take the whole PC apart (including the heatsink/fan from the CPU to re-apply thermal solution) and dust/clean everything out and re-do... i do it at least once a year... every time i get better temps as they get slightly higher over a years time...
