I originally had a set of Corsair memory, but I had issues with the mouse/keyboard input getting jerky and stopping completely at times. It occured during gameplay with a number of games, but not necessarily during peak processing moments of the game. I tested the RAM with MemTest86+, got numerous failures, and RMA'd them back to Newegg and purchased my G.Skill set (which all pass Memtest86+).
However, I'm still having the jerky input trouble. I've tried what seemed obvious to me (Memtest the new RAM, use a different mouse/keyboard) but to no avail.
I am using the stock heatsink that came with my i7-2600k, but I've never seen temps pass 60°C. My Sabertooth P67 has just about everything with the CPU set to 'Auto'.
Does anyone have some advice for where to go from here? It would be greatly appreciated!
Tried that as well with a few 2.0 and 3.0 USB ports, same issue. I've been afraid it's the CPU or motherboard, but I'm not quite sure how to diagnose an issue like that. Other things I tried that I didn't mention-
Switch BIOS version (tried newest and second newest ones)
Re-install OS (using newest drivers from the web for everything)
Ran Orthos Blending test (only for about 4 hours, though), no failure detected
