Power Supply Woes

hey. I just blew the dust out of my computer with an air compressor. i blew everyting off, including the power supply. once i put it back into my room and hooked everything up, i hit the power switch on the back of the supply. however, nothing turned on. i hit the power button on my computer to see if it would turn on... however, that didn't work. i moved the computer to a different plug, and it still wouldn't work. i'm hoping i didn't blow something that i shouldn't have. Maybe the air gun was too high of a pressure (90 PSI). I don't know if this is necessary, but my computer is an older eMachines. it has XP home, a gig and a quarter of ram, and an athlon XP 2200+ processor. before i blew it out, it worked well. The power supply is an ultra X-series blue/titanium modular, rated at 500 watts. it worked flawlessly until today. it isn't the stock one that came with the computer, and i bought this one in december 2007. can anyone help me out?

Pressure Too High

In reply to: Power Supply Woes

Using an air compressor with that sort of pressure behind it is much too high to use on your PC. It's easy to damage components that way. If you are lucky, you may have just dislodged a connector somewhere. Have you checked all connections inside the PC (drives, motherboard, PS, etc)? Check the memory sticks as well to ensure they are securely fastened in their slots.

thats kinda what i figured, i checked all of the connections, but i know it is the power supply because the computer doesnt power on when i flip the PS switch, and thats the telltale sign. im going to check a few other things though.

Inspect and verify

In reply to: yeah

Well, I've used the air blower often from my barn with no ill effect, but again anything can happen. As the other poster offered, reseat and check everything. Be sure the frt. panel power-ON/OFF is reseated as well. You can locate that connection and use a small screwdriver to manually touch the contacts for a moment and see if it power up then. Don't take anything for granted.

Not Necessarily The PS

In reply to: yeah

It may not necessarily be the PS. Your front panel switch is connected to the mainboard, and the PS gets its signal from the mainboard to switch on. The connector on the mainboard (from the front panel switch) is a small connector, which could have been dislodged. It may be labeled "FRT PNL PWR" or likewise. As Willy suggested, check that connector along with all other connections.
