Hey everybody I recently built a computer for a friend of mine and he's experiencing random shutdowns/crashes. I Built a practically identical system for myself first and have never experienced any issues with it. The only thing that comes to mind was the RAM timings, because I remember I didn't set them because CPU-Z showed the correct timing anyways, so I didn't bother setting them. So I'd really appreciate any help on how I can diagnose which component is causing the crashes, and how to fix it, thank you. System Specs Phenom II X4 965 BE @3.4ghz (STOCK) G.skill Ripjaws 4GB DDR3 1333 9-9-9-24 ASUS M4A785TD-V EVO MSI GTS450 (Not OC'd) OCZ ModxStream 700w PSU WD Black 500gb HDD Windows 7 64-bit Also a few weeks back he was getting random GPU artifacting, I updated the drivers and brought down the slight OC I did on the card back to stock. It seems to happen from what he tells me only when gaming.
