Windows 7: Dell desktop amber light flashing

I got a Dell desktop that won't power up. I've unplugged everything, plugged it back in, held down the power button...nothing. The amber light on the front just keeps flashing, even with the power cord unplugged from the computer.

Any ideas? Bad power supply?

I'd say so. Do you have or know anyone that has a similar computer? That way, you can switch PSUs to see what the problem really is.

Did the last poster actually read the original post - the guy's got a DESKTOP so it will be an internal power supply.... DOH....

Probably a power supply gone to heaven, but check your motherboard as it may have leaky, puffed-up capacitors.

Checking your RAM sticks are seated properly won't hurt nor will checking for a build up of dust inside your case.

Well this is a family members computer. I havent messed with it much I just noticed the other day when I was over she said she noticed the light blinking. She uses her laptop most and hardly uses the desktop, but it's still only like 4 years old. I'll pull the case off and see if there's any obvious signs. If not, she may have to take it somewhere.

Thx

No problem. Keep us posted as it always helps others if and when a solution is found.

A bent usb pin can cause the problem....might try cycling any surge/power strip switch off for about five minutes....check the voltage switch on the rear of the PSU

Sorry, I'm not sure how exactly I mixed it up, but I did. I've changed it though.

Has any progress been made on that issue? Also, out of curiosity, what's the model number on that dell? A dell Optiplex 380 (I think it was) had that exact issue in my office a few days ago. From the look of the issue I don't think it's a problem with the PSU, although I don't have an alternative explanation.

Bad power supply. Model number was Dimension 4700C.
