Question about Dell Computers & Internet
DELL optiplex gx280 won't boot and cpu fan goes faster and faster. The light on front panel stays orange, won't go green, and the cpu fan starts off slowly and increases speed until it is quite audible.
Sounds like a bad motherboard, I try resetting the bios , removing everything but the video , could be a bad power supply too (if you have one jump the wires in there as a test). you can buy those dell MBs cheap on fleabay.

Tips for a great answer:
For the Optiplex 320, a flashing amber light with no sound indication can mean 3 things.
1) Your power supply has failed
2) Your motherboard failed, most likely from a bad capacitor.
3) The front panel board (where the power button is located) is faulty or not connected properly.
I've worked with 10's of 1000's of Dell Optiplex's over the past 8 years and the flashing amber light is well known as a tell-tail sign of one of those three failure. Always start your trouble shoot with a PSU tester, then inspect the motherboard for domed or split/leaking capacitors...then on to the front panel which would require another panel and ribbon from the same model.
