2 days ago I turned off my computer to go to bed and when I woke up my pc was not working. The case fans and the led's on everything we're working fine. The monitor was in sleep mode and the mouse, keyboard and microphone did not light up like usual.I opened it up and tested all the ram, put in an old gpu, new battery on mobo, tried boot disks and the first time the screen mouse and keyboard worked for a minute and then they shut off and the boot disks never worked again. I tried unplugging all cords and plugging them back in and nothing. I asked a couple of friends and they said it could be the mobo or the PSU. I could really use some help on what is causing this problem, thanks for reading.

To see if it is the mobo or the PSU, test the PSU first by putting in another psu you know works or putting the current one into another working machine. Or you can use a psu tester but that works like 50% of the time and is not recommended. If it is not the psu, then take out the motherboard and the working psu. Take off the gpu and use the on board video. Jump the connector on the mobo. This process is known as bread boarding. By the way, before starting all that, just look at your mobo and see if you can see any bad capacitors or something obvious. Anyways, if problem is still there after just having those components, then take off heat sink and apply new thermal paste. If problem still there, then take off heat sink and cpu and...

Anyways, if problem is still there after just having those components, then take off heat sink and apply new thermal paste. If problem still there, then take off heat sink and cpu and look at the pins and see if any are bent. If they are, order another mobo. If not, try getting a cpu from a friend and using that temporally. If you cant, well 90% of the time when it comes down to mobo or cpu, it is the mobo. Very rarely is it cpu but it is possible. You can also try just putting all your other components into another pc except the mobo. If it boots, then your motherboard is bad, if it doesn't then report back here.
