Hi all, I've had a recurring problem for the last few months that I've just ignored but I finally have decided to attempt to determine the problem and fix. Any help you can offer, either in how to determine what is causing the problem or general solutions to hardware problems, is greatly appreciated. The Problem: My computer will randomly freeze/lock up and can only be recovered via hard reset. I have noticed that it tends to happen most frequently when playing a game on my main screen and try to do something on my second monitor (i.e. typing in skype, web browsing, etc.). My suspected culprits are video card and/or RAM. System Specs Main monitor (Samsung XL 2370) center, second (Samsung E2420L) to my left. Windows 7 Home Premium i7 2600k 16GB G.SKILL Ripjaws Series DDR3 1600 EVGA GTX 570 Gigabyte Z77X-UD5H Corsair HX850 128 GB Crucial RealSSD C300 (Windows Drive) 120 GB OCZ Vertex 3 (Games Drive) 1TB WD Black (Storage Drive) Thanks in advance for any help. Let me know if you need any additional info.
