So I've got an issue and I have no idea where to start troubleshooting. I just recently upgraded from an i7 870 to an i5 4670K, and from what I can tell the issue just started after the upgrade. Here are my specs:
Intel i5 4670K
2x 4gb G.Skill Ripjaws DDR3-2400
1x Samsung 840 250gb SSD
1x Hitachi Deskstar T7K500 500GB
Gigabyte AMD Radeon HD 7950 3GB GV-R795WF3-3GD
NZXT Guardia RB921 Mid-ATX Case
Antec EarthWatts 750W PSU
The problem occurs at random, I haven't really seen a pattern, although I have noticed it happening slightly more often when the PC is at load. I loose video signal, and the computer keeps running but is not responding. Right before losing the video signal whatever I'm doing usually locks up for 5-10 seconds.
Does anyone have any idea where to start looking into this? I can't seem to find anything in the Windows event viewer, but I might not be looking in the right place...
