Hi here are the specs for this computer I built myself. CPU: AMD X6 1090T MOBO: MSI 880G-E45 PSU: COODMAX 650W (some generic brand) Memory: 8GB Kingston DDR3 PC10600 CPU Fan: Thermaltake Frio Case: Antec Nine Hundred V3 HDD: 1 TB Seagate GPU: Onboard Radeon 4230HD That's basically all. Alright so I've had this PC working wonderfully with me for about 3 months now. When I first got the PC, I left it on stress testing just to see if everything will work stock. I HAVE NO OVERCLOCKED ANYTHING. The other day, I decided to see what temps I would get so I decided to test stress the PC and leave it running for about 20 minutes. I then left the room to use the toilet for about 10 minutes, and when I came back the PC was off. I then tried turning on the PC, and the blue leds on the FANs on the case turned on for half a second then turned off. With myself being in panic, the first thing I did was disconnect the HDD and other drivers and tried re-booting the PC but no success. I'm not sure if my motherboard somehow died under pressure. Could anyone help me out to see if it is not dead or what is the problem. Thanks EDIT: I had another 550W PSU lying around. I just tried it but still no luck. I then did the PSU paperclip trick, to see if the PSU actually turns on, and both PSUs SEEM to be working. For now I am sticking with my 550W psu just in case the 650W did something bad.
