Question about Dell OptiPlex 330 Desktop Desktop Computer
Mine's an OptiPlex 760, replacing the power supply Almost works. It posts for a second, then the fan revs up and the power light turns amber. No diagnostic lights, and I have also tried replacing the RAM, and CPU. Absolutely nothing. There are no bulged caps, anything I can do without going through Tech Support? :)

The first thing to check would be the CMOS to see if there is a setting for "case intrusion" or something to that effect. Some computers have sensor that goes off the computer's side panel is opened. I believe this can be disabled in the CMOS and/or it's just a wire connected to the motherboard that can be disconnected.
It could also be an important fan, like the CPU fan, isn't spinning fast enough which may or may not lead to an over-heated CPU.
Also check to be sure all the memory sticks are firmly seated.
If it doesn't look like any of those it could always the the power supply. See if you can borrow one for a little while for testing purposes just to see if it works.
If none of those pan out I would say call Dell support and see what they say.
