ok so my computer decides to not boot up anymore. i dont know why. i shut down my pc after checking my email and the weather reports before going out. when i come back, i press my power button and go take a shower. when i come back, the pc is basically hanging like it would from a bad OC restart. this is weird because the computer has been on stock settings and has been working flawlessly until now. any ideas? i tried resetting BIOS and all connections SHOULD BE fine since the pc hasnt had any problems until randomly now. edit: if my system doesnt hang, it'll just power up then shut off after a few seconds, then repeat. basically keeps turning on and off.
