Something has blown

[gibbo_ap]

afew weeks ago my computer decided to stop working; no video out, no light on keyboard.

i have tried swapping
mobo
cpu
tested another gfx card
psu
tried no ram, and each stick on its own
different monitor (even a different dvi cable just to check)
& reset cmos many times

nothing! same symptoms with what is in essence a new computer!

has any one any ideas?

the computer powers up (fans spin, hdds too)

getting very peeved

any help/ideas would be much appreciated

just a quicky . Im assuming you have two graphics card . Onboard and extra card

Try taking the GC out and using the onboard ? if that works .. then adujust the bios to use the Card instead

Hard drive ? i've had a faulty one once that stopped the pc from booting up. It seems you've swopped nearly everything else.

a collegue here has just suggested the case. i did actually think last night about the power button but at this point i had put the new mobo in which hasnt got power buttons on the mobo (i didnt think to use them when it was connected - doh)

Remove the board and bench test, i've seen a few over the years that don't boot, due to screws and other metal objects shorting the board and the case.

I had a PC here the other day that did the same thing . Except it wouldnt turn on with the power button or any i used .

A screwdriver worked though shorting the two pins

Sounds ridiculous but have you replaced all the SATA and IDE cables? I looked at one computer with similar symptoms and it was the IDE cable.

Also, what @difinity said, ensure the case isn't shorting out components.

have tried without hdd, should still go to bios with hdd right?

It should go to BIOS without HDD.

*Whispers* Cables Cables Cables. SATA and IDE.

as of last night the only remaining cables i had yet to test are the case ones. all sata, ide, power cables had either been swapped or removed

I had a computer do exactly that, turns out I'd forgotten to plug the second motherboard power cable in - the small, four-pin one you sometimes get (is that a 12V connection?).

lol would love for it be this simple although it had been working fine for 3-4 years

Righty, first off, your AW9D should have a post probe on it which displays 2 digit boot and error codes - does it have anything on the display? If so, give us the error codes.
If not, take mobo, CPU(+fan) and PSU. Wire up on bench. No ram, no graphics. Turn on via shorting powerpins momentarily with anything metallic. If fan spins up but you don't get any beeps whatsoever / no display on the postprobe, then either bios is corrupt and needs hotflashing, or CPU is dead, or mobo is dead beyond repair.

If you DO get beeps, then all those components are fine. You now need to add ram and graphics and try it again to see if you can get to the POST screen. Only add ram one stick at once, testing each stick individually.

Bios HotFlashing (repairing a corrupt bios chip) -There are several guides around the web for doing this... eg:
Step-by-Step Tutorial on HotFlashing a Corrupted/Non-Working BIOS Chip - Overclockers Forums
Tech ARP - Hot Flashing Guide Rev. 2.0
How to hotflash your bios chip - Overclock.net - Overclocking.net
Failing that, head to bios-repair.co.uk | Flash BIOS Chip Repair | Flash BIOS Chip Replacement and order a replacement preprogrammed chip.

If all else fails, post in the "abit.care" section at Hexus.net's forums and see what advice official Abit reps give.
