I Just had to replace my motherboard and power supply due to my old PSU dying (and you know that it is rare that the PSU dying doesn't kill the MOBO or something else). Now it is just randomly shutting down (without a BSOD sadly). Sometimes it is just random, just sometimes it is either during internet browsing, playing Half Life 2 Deathmatch (usually when at Skul`Shock), or video editing (that was a recent one). Here are my specs. ASRock N6-8C GS FX Motherboard COOLMAX 600W Power Supply Windows 7 Gamer Edition (x64) NVIDIA GeForce GTX-550 Ti (1GB GDDR5) 2 Seagate HDD's (x1 500GB and x1 1TB) 8GB DDR2 RAM by KomputerBay (Samsung rip-off) AMD Athlon II x4 630 (2.8 GHz) No Overclocking is being run, at least I don't think so... TSSTcorp DVD drive x2 Monitors (HP S2031 20" and HP W2071d 20" through VGA to DVI connectors.) Any help is GREATLY! appreciated. Thank You!
