PC seems to have died

Hey everyone, I hope you can help me

I have an old (2 year old) Alienware Area-51 i7 920, 6gb ram, gtx260 1.8gb, 2 Hdds (750+1TB), asus Mobo and Asus sound card 5.1.

Over the weekend I fell asleep in the evening with my PC just playing a TV show. In the morning, it was dead.

What I did:

Unplug and then plug, and try, nothing.
Tried removing all parts and cleaning, and trial and error with what to replace whilst checking if system worked. Nothing seemed to help.
Did the remove the battery thing on the Mobo, no help.

Strange things:
Mobo has power and reset light lit up
Case fans and lights spin for half a second and lights flash but then die.
Tried friends PSU from almost identical system (mine is 750w PSU, his was 650W), nothing happens apart from PSU fan almost starts to spin (like a jolt)
Tried my video card in my friends PC (both gtx 260) and didn't want to even recognise it.

I have a feeling either Mobo died, issue with PSU (yet why does friends not work either?) or video card died and is causing issues.

Require anything let me know, currently at work though.

Thanks!

if you try to start the system without the gfx card in do you get any beeps, does it try to spin up.

does the mobo support sli (ie is there another pci-e slot u can try.

what make/model are the psu's.

Pretty sure I tried without graphics in and it was the exact same issue.

No SLI support :/

My PSU is Alienware branded, I think my friend's was CoolerMaster

Tried with 1 stick of ram?

Or take graphics card out, reset cmos by doing the jumper thing or removing battery then try.

Tried reset Cmos, tried 1 stick of ram in different slots, different ram sticks. All with graphics out and in.

All I get is flash of light, case fans try to spin and then nothing.

Any beeps?

Just from what youve said, Id put my money on the PSU failing and taking out other things with it (it is alienware after all, just a rebranded cheapy dell).

No beeps, dies like .5 second after power is turned on

This might sound stupid but the only time I've seen this is due to bent CPU pins. Take out the CPU and check that no pins have bent / snapped.
