hi everyone, i'm having a strange problem with my CPU, during gaming and almost all programs im getting usage drops down to 0% every couple seconds for no apparent reasons, in gaming this results in 1-2 second freezes and framerate drops from 60 to 45 or lower.
my temperature never goes above 50c, so its not throttling, and ive disabled all power saving features in the bios. I've tried running at the default clock speed and voltage, tried auto settings and even underclocked, but the issue still persists. my power settings are set to high performance but i have tried balanced, neither changed anything. i am running my games off of a 2tb WD green harddrive but the same problem occurs when loaded off a ssd as well.

this link shows my cpu usage in a prime95 test, it behaves similarly in games,but hovers around 60-80%, then drops to 0% usage

all help is greatly appreciated :)

okay, so ive installed windows 8 and tested my cpu at stock and surprisingly it works fine, actually had a few more fps in crysis 3 than i did on win7, so i guess my problem has sort of been solved, too bad upgrading to windows 8 was the fix, thank you guys for all your help :)

I really can't think of what the problem could be, I haven't encounter something like this be for. I would recommend you send a PM to one of the experts here on Tom's Hardware, I would suggest a user like i7Baby.

My last recommendation would be to check for an update for your GPU drivers and make sure you have the most recent Windows updates installed. I hope you manage to solve this issue but I have reached a dead end for solutions.

Which OS? Make sure all drivers are up to date and all windows updates are done, as the fx line has hotfixes from windows. I know it sounds like a waste, if u have an extra drive or all your important data off your hdd, try a windows re install or install on a different drive.
