Since this morning, my computer won't start. I was using it normally (playing) and it suddenly turned off. Now it won't start. Sometimes, when I press the power button, it starts for half a second to a second, and then turns back off. I noticed this happens more when I unplug the power chord and plug it back in.
I didn't change anything in the hardware, and I don't think it's a software issue since it doesn't stay on long enough for anything to boot.
I'm thinking it could be related to my power unit but I want to be sure before replacing it.
How do I diagnose and fix the problem?
I plugged my power chord on another computer and it worked (at least it stayed on). I also checked that everything is properly plugged in on the motherboard.
