Hey guys, my housemate's having real troubles with his computer. I've done what I can but honestly I'm at a loss. Basically it's hard powering off (not a Windows 7 shutdown) regularly. Seems to be increasing in frequency. No bluescreen, nothing in the logs other than "hey your computer shut down earlier that probably shouldn't happen." Initially it restarted right away but now it's taking longer and longer to come back on. Didn't seem related to load. At one point it repeatedly did it while trying to boot into windows and never got past the loading screen until it was disconnected from the power. However my housemate's started playing WoW again, and for a while it was fine but now it's happening pretty shortly after he launches it, every time. It's plugged into a power board along with the screens (which don't shut off). He's tried switching sockets and cords for the computer. It's not heat, temps have been checked and are fine. RAM has passed memtest86+ passes. I did a basic check with my PSU tester and it looked okay. It's a pretty new system, the specs are i7 3770 8GB RAM (G.Skill F3-10600CL9D-8GBNT) Asrock Z77 Extreme4 CoolerMaster Hyper TX3 Evo Palit GTX 770 2GB Silverstone Strider Plus 600W ST60F-P Samsung 840 Pro Series 128GB SSD and 2 HDDs So yeah, any ideas? We're up to multiple times a day now.
