PC Dead

My PC had a problem with random restarts for a while, it now almost always fails to start at all (apart from once in about 30 tries last night).
There are no beeps at startup.
The Hard Drive spins up, as does the CPU fan.
I disconnected all drives, modems and tried to get it to start but to no avail. I also tried to test the memory by removing each of the sticks one at a time...
Any ideas?
Thanks!

Try another PSU.

I've bought another PSU, still doesn't work I'm afraid! Any ideas??

Hard drive and CPU fans spin any leds lit on CD etc.?

No beeps

Could this be a monitor / g card problem?

Disconnect Hard drive and remove PCI modem if there is one. Then see if it will boot so you can get to BIOS. Note how long it takes

Monitor is fine - I have another PC.
It's on board graphics. But I really don't think its this as even though the HDD spins up, it doesn't kick in like it does when the operating system is loading up...

I've disconnected everything apart from 1 stick of RAM - still no beeps

For beeps the Case Speaker may have got disconnected

The one time I did get it to work it beeped, i haven't disconnected anything since then...

Reset the BIOS and see if that helps. Taking the CMOS battery out for 10 minutes or so also helps sometimes. You can also try without any RAM at all, that should produce error beeps. If you have disconnected everything from the motherboard (except the PSU, processor with heatsink, case speaker and power switch, then one of the remaining parts has failed. You can try the reset switch in place of the power switch to see if that's the problem. After that there's little you can do other than try replacing the remaining bits. You've tried the PSU so then it's the motherboard or processor. The only other possibility is that the motherboard could be shorting to the case, so take out all the screws and stand the motherboard on a sheet of card or similar insulating material.

Ok. I'll try to test if it is shorting to the case. In the meantime - I'll check out Ebay for replacements! Thanks...
