fried motherboard or psu or other?
hi i have amd sempron 2400
so one day while i was on my computer surfing the web, my computer shuts off all of sudden without any "pop" sound. when i try to turn it back on it wouldnt work. so i got a used power supply which is kind of new and then installed it. It still didnt work. so i took everything off from the power supply execpt for one rectangle outlet that connects to the motherboard. on my motherboard there is ram, graphics card. This time when i press the power button, the motherboard fan runs for 3-4 secs and then slows to a stop. Btw there is no loud beep sound.
So then i put on the square outlet into the motherboard additional to rectangular outlet. When i press the power this time, the motherboard's fan doesnt run, but it twitches.
What do u guys think the problem is??
