Half Second FPS Spikes.

Two make a long story short the stock Intel heatsink I installed sucked and never sat right. After two years I finally picked up an aftermarket heatsink when my cpu hit 90C when playing Borderlands 2 and idled around 40-50. My temps have never exceeded 55C even while streaming, recording/playing.

The problem I'm having is after trying to re-sit the stock heatsink and buying an aftermarket I'll end up having weird performance drops. I can still play League of Legends for example at the same FPS, record/stream at the same FPS. However I'm now getting some lockups when playing games. For example I'll be at 120 fps in League only to have it lockup for half a second to a second and either have it show a drop to 30 FPS, then climb back to 120 or it will show no drop in FPS.

This persists within a few games but is the worse with League.

I'm guessing its hardware related so I'll list the specs of the hardware that is probably at fault (PC is 2 years old).
GPU: Radeon 5850 (hits 75C underload often)(Also have two monitors hooked up)
CPU: Intel I5 2400 (highest hit was 90C, new heatsink 53C)


TLDR: FPS lockup in games, could be anything from the CPU, GPU, or PSU.

try to download new drivers, had similiar problems with battlefield 3 myself, game would froze for half a second like every other second, and that fixed it.

edit : i just had an sapphire HD5850 at that time. :D

Updated Drivers not too long ago, but decided to update again. Unfortunately updating drivers gave me a BSOD. I don't believe it is driver related and feels it may be hardware related but I'll try the process again later and hopefully it chills out this time.
