I have a Dell Optiplex SX270 Desktop that has always ran windows XP and it has ran acceptable. I shut it off Friday at the end of business and went to turn it on Monday and it will not turn on. I assumed it could be the PSU so I swapped it out with another adapter from a similar computer and it still doesn't work. The light on the mother board will turn on but the fans will not. Dell's support site said to take out the hard drive and the ram but this didn't have any effect. They said that after the ram is taken out and you try to power it up again the system should emit a beep code, but this did not happen. Does anyone else have any suggestions for me to try?

Unless you have a power supply tester, and a spare known good power supply, the best thing to do is to take the tower to a shop and have the power supply tested. If the power supply tests "bad" then they could jump a known good power supply to the motherboard and see if the board is good.

I do these tests in my shop quite often. It takes about 20 minutes and the cost should be minimal, perhaps $25-$30.
