Cran. Posted August 6, 2007 Share Posted August 6, 2007 I think the PSU on my desktop is gone. When I press the power button, nothing happens. If it was a different part that failed, the computer (i'd assume) would at least power up. So, PSU gone? Specs Pentium 4 3.2GHz (s478) 1GB DDR1 PC3200 RAM 2x 80GB WD Caviars Thermaltake 420w PSU It's about 4 years old. Link to comment Share on other sites More sharing options...
Primer43 Posted August 6, 2007 Share Posted August 6, 2007 Probably, if your not getting lights. Link to comment Share on other sites More sharing options...
Edmachine Posted August 6, 2007 Share Posted August 6, 2007 Make sure the PSU is on . If is, check the cables. Maybe the cable is broken, try checking that. If it is ok, try getting the dust out of it... maybe that would help?

Loman Posted August 6, 2007 Share Posted August 6, 2007 It sounds like a PSU problem to me, too. Make sure that none of the cables/cards have come loose, and make sure none of the empty connectors' ends are touching any metal in your case. Like Ed said, make sure the I/O switch is turned on (I), if your PSU has one (I've done that before).Try different external power cables and different outlets, too, couldn't hurt. Maybe see if a friend will let you try their PSU, to make sure. Link to comment Share on other sites More sharing options...
matthew1g Posted August 6, 2007 Share Posted August 6, 2007 Do as ed and loman said, and check if any of the connections have rusted. That could interfere a lot Link to comment Share on other sites More sharing options...
Cran. Posted August 7, 2007 Author Share Posted August 7, 2007 None of the connectors seem to be rusted, and yes Edmachine I double checked if the power lead was in the back and it was turned on! Boy has that little switch allowed me to have some fun with people! No lights turn on or anything. It's like it's getting no power at all.. that's why I thought it was the power supply. But I kinda jumped the gun and took it out.. Link to comment Share on other sites More sharing options...
Edmachine Posted August 7, 2007 Share Posted August 7, 2007 Did you say what I think you did? You have a gun in your PC?!? We will be the arms that lift you up We will be the hand that strike you down Link to comment Share on other sites More sharing options...
K^2 Posted August 7, 2007 Share Posted August 7, 2007 Cran, and anyone else who haven't done so. If you are going to fix your own PC, for crying out loud, invest in a multimeter. If you get an analog one, they are dirt cheap. Though, digital ones are worth the price tag. Suspect a problem with power supply? Power it on and check the voltage red-to-black and yellow-to-black. Should be 5V and 12V respectively. Prior to filing a bug against any of my code, please consider this response to common concerns. Link to comment Share on other sites More sharing options...

K^2 Posted August 8, 2007 Share Posted August 8, 2007 I think it's going to depend a lot on the functionality it has. Personally, I would look for something with direct/alternating current voltage/amp measurement, a decent resistance and capacitance measurement, and the frequency measurement. I'm not sure if you'd be able to find something like that for $10, but for $20-$30 for sure. That's going to cover most of the stuff you'll need to test in the computer. For more advanced checks you'd probably want an oscilloscope anyways. Prior to filing a bug against any of my code, please consider this response to common concerns.
