Chrisis: PC will not turn on
Hello everyone, I have a problem that's new to me and really has me stumped: pressing the ON button does nothing.
Old Dell Dimension 4600. 2gig ram, 512mb GXP vid card. 460w Everex PSU. Two hard drives, the master has winXP on it, the slave has win7 on it. It dualboots into win7.
What Happened Right Before This Started:
Firstly, my computer has been running fine and I have not cracked the case in about six months. I turned on the computer and noticed that it was not connecting to the internet. So I first restarted my cable modem, then restarted my router, to no effect. I then pressed "control - alt -delete" and the computer started to get to the point where it would give me a window of options, but hung up. I pressed the escape button, then the windows button, and the screen went black. So I waited for a bit and held in the ON button on the front to force it down. Nothing happened. "Oh crap" I thought, "this has never happened before." So, I turned it off by flipping the power switch on the power supply. I waited a minute, then flipped it back on. Then I pressed the ON button on the front and nothing happened.
What I Have Tried:
I swapped the PSU's, but nothing changed. I have disconnected and alternated the two hard drives. I have vaccumed the cat hair out of the inside of the case. I have unplugged and replugged everything many times. I tried plugging the computer into a different wall outlet.
What May Be Important Hints:
Usually, when I plug the computer into the wall the fans inside the computer turn on for a second. This is not longer happening. That's why I thought it was the PSU, even though it is only three years old. There is a little LED on the motherboard that DOES still light up when the PSU is switched on.
So, I'm afraid it's the mobo or the PSU that is the problem... What do you all think? This is my main computer, so this problem really sucks.... Thanks in advance!
