My computer stopped working in the middle of me using it. It wasnt a sudden stop like something was unplugged or power was disconnected but it shutdown and wouldn't power back up. I replaced the power source but still nothing?
Try resetting the CMOS, its very possible the motherboard has went out. Specs of your computer? Both old and new PSU? How long have you had the motherboard/ CPU?
Ill reset it when i get home, but its a stock computer I found for cheap on amazon and ive slowly started upgrading the parts, a 650 power supply and I cant remember what graphics card I have
