So here is my problem. last week my computer completely shut off and wouldnt turn back on. the motherboard lights were still on so I assumed it was the psu and went out and got a new one. my computer worked fine for the last 2 days since I got my new psu but I have also been overclocking my gpu. today while playing games my computer shutoff again and wouldnt turn on. I unplugged the gpu amd the computer booted up fine then when I went to restart the computer to access the bios it would not turn on and still wont. any thoughts to what the problem could be?
