My girlfriends computer will not turn on. it was off for about 6 months before i pluged it all back in. and it would not turn on as if it had no power. so i thought it was the power supply. so i got a new one. it had a 250 watt power supply and i put in a 350 watt power supply. it did turn on for about 2-5 min then it shut off and would not turn back on again just like before. is there somthing i can do before i take the power supply back and get a new one.

Do you hear any beeps when you turn it on, if so then that may mean that the memory is bad, but not always. Second, try taking the modem out if it has one, modems sometimes make the computer not turn on, not sure why, but it does happen. Let me know about those things, I have other ideas after that.

The PSU connector, is it a 20, 24, or 20+4 connector? was it loose? Also, is it possible that in the 6 months of not using the computer *Blasphemy*,that ESD (Electro Static Discharge) Got in there?


Was the computer dusty when you opened it to put the new PSU in there? Are all of the ATA tapes (The gray tapes connecting the Hard drive, floppy drive, DVD drive, etc) All connected to the MOBO Securly?

When you installed the 350 watt power supply and it ran for 5 minutes did it boot to windows ?

What make and model of computer is this ?

Hey what about the simplest thing in the computer? It is the CMOS battery, if the computer sat for 6 months and the battery probably went dead as a door nail. No battery power nothing in the CMOS and no boot up.

I have to thank everyone :thumbsup: i ended up getting a new power supply and i did change out my cmos battery. everything is fine now. i dont know if i ended up frying the other power supply or if it was just factory bad. thanks everyone again.

It was most likely a DOA. There's no way a motherboard can get a power supply to go bad, only the other way around.
