Comp is suddenly turning off by itself at random. My computer is turning itself off at random. like it losses power. not logging off just off and restarts and shows the start windows normal. there's no particular activity that triggers it. but i think it happens during only when i use it. i can leave it on during school and it did not turn off. my system is. i7 950 COOLER MASTER Intel Core i7 compatible V8 CORSAIR 12GB (6 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit EVGA 896-P3-1170-AR GeForce GTX 275 896MB 448-bit DDR3 Corsair P128 (CMFSSD-128GBG2D) 2.5" 128GB SATA II WD 300 hdd WD 500 hdd Seagate 500 hdd all normal 7200 rpm sata SAMSUNG 22X DVD±R DVD Burner Black IDE Model SH-S222L LightScribe Support - OEM 7OCZ ModXStream Pro OCZ700MXSP 700W ATX12V V2.2 / EPS12V SLI Certified CrossFire Ready 80 PLUS Certified Modular EVGA 141-BL-E757-TR LGA 1366 Intel X58 ATX X58 SLI LE Intel Motherboard vista 64 business It just gives up randomly. I can be using it for hours or maybe minutes it just gives up. What do u think it wrong? My power supply is connected to a 6 outlet power strip which is full ( all 6 connected. ) I am thinking it is a psu problem. either too low. or faulty . this is driving me crazy. I hope it is not a MoBo problem.
