Earlier I posted this thread: http://www.tomshardware.com/answers/id-2340190/4670k-broken.html, about an issue I was having with my CPU.

I reformatted and the problem was fixed until I launched the game Payday 2. A few minutes into a test match, I got lag spikes every other second on my CPU.

This is a screenshot of how my CPU is acting when I play it, the lag spikes continue until I reboot the computer. If I try and play a game or launch a CPU intensive program like Wprime the issue comes back.

System Specs:
i5-4670k
ASUS Z97M-Plus
4x4GB Kingston HyperX RAM
GTX 760 WINDFORCE
AzzA 850W PSU
2x 1TB Seagate Barracuda

I tried an earlier driver, 337.88 for my GPU, but it made the issue happen even on idle. Using driver version 344.11 I get random Windows NVIDIA Kernal mode driver crashes.

Please someone help!

It's not a defective GPU, I've had it for over a year now and it has worked fine. The only changes have been swapping out the mobo and cpu and adding in a new HDD.

I'll try Prime95 torture test, and get back to you.

Testing it in my i7 950 build I get zero lag, it boots up as normal and runs games fine, it's only in the i5 build do I get lag doing menial tasks.
