Hello. Last night I turned off my computer and went off to bed. When I woke up this morning I tried to turn on my pc but it failed to boot. This has previously happened to me and out of some stroke of luck i managed to fix it but not this time. Basiacly i opened up my pc and did waht i did last time. I unplugged the power cable from the computer (from the power supply) and replugged it in. On my Motherboard i see a green light indicating that i do have come form of power in the MB. But whenever i push the power button to start it up i get a very brief (less then a second) startup where the computer makes the noises of powering up and my blue led on my fans start to light and my fans spin but then it seems to just shut down. Just as some useful information, my computer will only do that very brief startup if i completely unplug the power from the power supply and let the light on my MB go out, upon replugging it in when i push power it happens again witht he brief startup. Im not really sure whats is causing the problem but i really hope it not my MB being broke I have tried unpluggin my hard drives video card and ram. Any help would be Hugely appreciated THANKS!
