Let me just toss this out there for consideration, processors very, very seldom go bad or "cause" problems. 99.999% of the time it's something else. So, just sayin, thats all.
he says hes getting strange fps drops in games. like dropping down to 30-40fps randomly or just when starting out a game it'll drop. it happened in thief, and bf4. after re-installing drivers the clean way, the 30fps issue hasnt happened yet, but he still gets drops randomly from areas he should be getting 100fps in and strangely he gets 75fps. when he runs back to the same spot it will be at 100fps or more, and when he looks up into the sky to watch the fps go as high as it can it sometimes only goes up to 135 or 150 and drops back down to 75 when he looks straight again. its weird. he tried changing out all parts of his computer, and nothing has worked. he hasnt changed the CPU yet though.
