Hello friends, I am not sure what piece of hardware is at fault here on my friend's PC, so I will begin with how the problem began.

He shut down his PC last night; he turns it on today to find that it does not POST. That is to say, it does everything up to the green splash screen for his Asus m4a78lt-m, but does not actually POST, after which nothing happens.

He can access the BIOS but cannot do anything inside it, his PS/2 keyboard does not work.


What have I tried so far?

- Testing RAM sticks in different slots (including working RAM from another PC)
- Reseating the graphics card
- Cleaning Graphics Card/RAM contacts and slots
- Resetting CMOS (removing the battery and putting it back in)

And various combinations and iterations of the above.

So I thought perhaps the motherboard went dud. The PC was bought as a pre-built system nearly 3 years ago, not sure if there is still warranty on it. Would I be correct in advising him to replace the motherboard? Is there anything else I could do?

Thanks, OcUK-ites.
 
What Bios version is he running, the latest according to the Asus website is 0802.
You could try flashing the bios if he has an earlier version.
Does he have any USB devices connected?
Are there any red lights flashing on the mobo, assuming the board has led warning lights.
