Again, I don't know much about them so either of those could be totally wrong.

Guest Posted January 11, 2010 Report Share Posted January 11, 2010 usually there is a light that turns on on the motherboard itself when you plug the cord into the power supply, even if the computer is shut off, the little LED should be on. on my computer it is green and a few others i have seen are green also. its generally near the CPU heatsink and the dedicated ports.

Guest Posted January 11, 2010 Report Share Posted January 11, 2010 heres a nice PSU i found by googleing your computer model and power supply at the end of it. not bad for $45 IMO http://www.atxpowersupplies.com/630-watt-p...630WPS-SR1820NX $30 more expensive on ebay? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...4=263602_263622 edit: this is the absolutely last step if you cant find a solution Link to comment Share on other sites More sharing options...
Neel Posted January 11, 2010 Report Share Posted January 11, 2010 Alright so now that you have it open, grab a paper clip and a voltmeter. Remove the main 24 or 20 pin connector from the motherboard. Once removed, find the green wire, insert the paperclip into the green wire and then stick it into any prong with a black wire or even the chassis of the computer. The green wire is the "remote" to the power supply and when its grounded the power supply will turn on. So do that and then with your volt meter , prong any 4 pin molex connector. So on your voltmeter , put your negative prong anywhere on the chassis of the computer and put the positive prong in to a yellow wire, it will read around 12v. Also red wire will read around 5v. If you get no readings .. or get some weird readings you have a bad power supply. Not a big deal, just go to your local computer store and pick up a new one and then stick it in and see what happens!! Too Much Stuff to list .

Guest Posted January 11, 2010 Report Share Posted January 11, 2010 http://forums.techguy.org/multimedia/69287...n-flashing.html i just read that you can smell the back of your power supply (the fan outlet, make sure not to inhale dust lol) and smell for electrical burning. i assume it would be similar to a sub coil heating up Link to comment Share on other sites More sharing options...
