Hello guys! I'm having big problems with my PC, the short story is that it doesn't power on. It does power on but it is displaying nothing and there is non beep sound associated with errors. I Disconnect virtually everything: SSD, HDD, GPU, RAM and it doesn't beep not even once. That indicates that it is the power supplie or the motherboard, I did check the power supplie with a clip by "short circuit" green cable and a black one (motherboard connector) and fans started to spin up, but I don't think that matters since already was starting up. Sow now I think it's either the power supplie delivers wrong voltages or the motherboard is broken, if the motherboard is the problem, I am waiting for a friend to see if he has a POST card, but I don't have high hopes. I have to mention that it happened before, but after letting PC to rest for a night it would power on and other times it took more time then usual to reach the typical beep sound and start to windows, also I had some windows crashes with error "DRIVER_IRQL_NOT_LESS_OR_EQUAL; ***STOP: 0x000000D1" and it doesn't have not a file associated with it.
Thanks to everyone!
