Re: Dimension 8200 will not turn on

Try a new power button. Also does the machine power light turn on at the front of the machine? if so check that the CPU is seated correctly as if it has come out of position then the machine doesn't boot. I would like to think power switch though.

Thanks J

Re: Dimension 8200 will not turn on


It's very possible that your power supply has gone bad. A friend of mine brought me a Dimension 8200 to look at a few months ago that was acting exactly like yours. At first glance, I assumed that the power supply was ok because the LED on the motherboard was lit up. I decided to check the power supply with a tester and found out that the only live lead was the +5 VSB (5 volt stand by) which explains the LED being on. I replaced the factory 250 watt power supply with a 350 watt and it happily booted up. Keep in mind though that you may need to make a slight modification in order to use a non-Dell power supply. I had to make the opening in the back of the case slightly larger so I could plug the power cord into the power supply.

Good luck,

When I turn on the dell dimension 8200 the light on the power button does not turn green, it stays amber color blinking and the computer does not turn on, is it the power supply that is gone bad?

Check all below possibilties & see if it works.....
  1. GGGY diagnostic lights can indicate a bad motherboard, or possibly a hard drive failure.You could try opening the case, then remove and reseat all the power and data cables, cards and memory and see if the system bootsCheck for burnt/charred power connectors on the motherboard and for any capacitors with bulging tops or are leaking, the tops should be perfectly flat.
  2. Could you please check out if the you are not having a battery problem. This could be the source of all the trouble that you are having.
  3. do the fans and hard drives spin
Please rate & vote, if you like solution

Dell Dimension 8200 Desktop PC shuts off after it has been on for a long time. It shuts off like power has been removed from the CPU although I have an APC hooked up to it.

Sir you should check the power supply of your system.If its working properly then its because of the heat sink of your motherboard...Try to mother heat sink fans in the pc and your problem is solved......

Main power button LED is flashing or solid yellow

This is a major problem that crippled Dell. Moels Optiplex Gx260, Gx 280, and Dimensions of whose mdel number i don't remember have this problems. This signal shows that either a power supply or your motherboard is malfunctioning. If you have an insurance better use it now or else get some technical assistance.

I need the LED/power Button Cable Assy. for my Dell Dimension 8200 PC Desktop

Best way to get one of these is to go to a local independent computer service center and ask for what you need. The LED/power button wires are pretty typical in all PCs. So, they should be able to fix you up with little cost.
