    Default Computer not turning on

    My computer was running fine in the morning. I set it to sleep while I went out to run some errands. I came back less than an hour later and it doesn't turn on anymore.

    Any suggestions on whats wrong? I don't know if its related but I often got BSOD errors while the computer was set to sleep.

    Specs are
    Core 2 Duo E6600
    Gigabyte P35 DS3R v1.0
    2 x 2gb Corsair, although they are different models
    2 x 1gb G.Skill
    Enermax Liberty 620W

    Computer is about 3-4 years old. I'm assuming the Power supply died for some reason, is there any way to check?

    What version of windows is on it, and what was the stop error for the BSOD?

    It was running Windows 7. stop error? Is that referring to the information that pops up on the bsod? If so i'm not sure. I only knew it was bsoding because when I tried to wake the computer from sleep, it wouldn't respond, and i would have to press the power button to start it up again. Upon windows starting up again i would get the message box saying windows has recovered from an unexpected crash, and it would display BSOD as the reason, but i didn't look further into it as it would never bsod on me while i was on it.

    Well actually it had bsod'ed frequently before while i was on it, but that was due to faulty memory module, which replacing fixed.

    Yup a BSOD usually brings up a stop error with something like xxxx and it may also show the name of a file or driver.

    Does the on/off button feel stiff? I would check and see if its making contact. I would say its either the power supply. Or the on/switch may not be making contact. I would open the case, and see if anything has blown like capacitors. If it doesnt turn on at all

    Pull the plug out at the wall socket. Leave it all unplugged for about 10 mins, then try again. Sounds silly, but I've seen this work.

    Or maybe the CMOS battery is flat?

    Make sure it is switched on at the wall

    Seeing you have 4 ram modules, and you have had problems with ram before, try removing 3 of them. Failing that, remove it and try another one.

    I borrowed a PSU from one of the other computers and my computer turned on fine. I would have thought a $250 PSU would have lasted longer than 3 1/2 years :/

    Any recommendations on a replacement PSU?
    I was thinking of this 550w Cooler master one.

    My GPU is a 4850, and i've only got 2 harddrives. 550W should be enough right?

    Also might it be possible to salvage the enermax somehow?
