Random freezing issue

[fireslayer26]

I keep having a random freezing issue. Most likely a hardware issue but I'm not sure what. When the cab is running it runs great. But sometimes, randomly the whole pc will freeze as seen in the attached video. What could the issue be? RAM? etc?

I would recommend checking Event Viewer to see if any application, hardware, or OS events are being logged at the time of the freezes. You will run the gammut for possible causes: RAM, power supply, GPU, corrupt OS, etc.

I will see what I can find out with event viewer. I have a 750watt PSU and just added a second video card. (it was freezing before this too) Also, just did a fresh windows install. This is really starting to annoy me. Also, I made sure all power saving modes where turned off.
