Having problems with your Dell Dimension 1100 PC Desktop ?

Power supply fan is loud!

\015 I would like to know what type of power supply I need for a Dell 1100 desktop. I called Dell and they told me the part # was H2678 and that it was a 250 watt power supply. I see plenty of power supplies available at many different locations, but I really don't know which ones are compatible.\015

Answers :

I think that with a system as old as that is you should find one that has a 20 pin and the form factor should be ATX. I found one that should work here it isn't bad for the price.
It looks like you need an ATX power supply. You could go higher than 250 watts, but don't go lower. 300 to 400 watts should be a sufficient replacement. Any bigger would be overkill.

My Dell Dimension E510 is making a "whirring" noise. It whirls loudly when I turn it on, like something inside is struggling to get up to speed. The computer takes more time than usual to become operable and open programs. Then with the computer on, the "whirring" comes and goes, it is more quite, but more uneven. Sounds like it's going fast sometimes, then speeds up and back and forth. I've opened the computer and cleaned the dust out of it. That didn't help. HELP. VHS
