Dimension 8200 no video

A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Starting piont would be the power supply. Any power there at all? Test with a voltmeter.

Thank for the detail, it really helps...
Most people forget about the power supply. If the power supply overheats, it will shutdown. When shutdown, it will cool off then operate again.

A power supply goes by WATT ratings, the average size power supply is now 450 watts for an average system and should cost around $60.

good luck and don't forget to vote.

The clinking sound could well be your drive heads snapping back into parking location if your power supply is going out. Since the 8200 comes with a pretty weak power supply those tend to go out shortly after you've upgraded to a better graphics card or added another drive to the system. I've replaced mine a few times and now have a 450 watt supply in it which seems to be able to handle a powered video card and the 2nd HD, 2nd dvd without running out of juice.
Another good thing for these old dimensions is the addition of a case /slot fan to help with cooling a bit more. (see included picture)
I've had dealings with a number of dimensions from this era not cooling enough and the slot fans really helped stability.
Let me know if any of this helps your situation.

Probably a bad power supply? If you are not getting any power. They are inexpensive and easy to change.

If the power button does not light up at all, I would guess the power supply has a problem.

plz check your power supply

I have a couple of graphics cards that will do the trick. Email me back and I will help you out.

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
