Open up your tower and take out the ram. Then put it back in and close the case. Make sure your power cord is disconnected when you do it. Then restart and see if it helps.

You will have to get your power button unstuck. I do not know what type of button you have but if you would like to at least get your PC on without it instantly turning off, you can remove the power switch connector from the motherboard. You will eventually need to have the switch unstuck, or replaced though.

Did you open the case on your computer? It may have an open case alarm which is a small switch typically located near the edge of the cover you removed. Make sure the case cover is completely installed, then see if the alarm goes off.

Yep sounds like a bad PSU. There should be a warranty on this thing so I would call Dell and tell them the problem and they should be able to get the problem fixed for ya, the only thing is that you may have to ship it to them cause I don't think they'll take your word for it. But I would definitely call Dell at least you'll know your options then.

Computer will not turn on at all. Dell Dimension 5100 desktop


I would unplug the power supply from the motherboard, wait a little while and then plug it back in.
Try to power everything back up and it should come up.

I am assuming you are getting a light on the motherboard that indicates power is being supplied?

Dell dimension e510 won't turn on


Unplug the power cable from the power supply in your computer and reinsert it. If you still have nothing, most likely a dead power supply.
