Computer help please! So my stupid computron keeps dying in the middle of stuff. Just completely powers off for no reason. I am almost completely computer illiterate so bare with me. I took off the back and looked for loose wires. Nope. I actually vacuumed out all the dust. I am pretty sure it's a hardware problem. I just replaced the motherboard about six months ago. I think it may be the power supply. Any way of checking this before I have to go out and buy a new one? I hope this posts before my computer shuts off again. Arghh! Very frustrated.
