bios

I have an annoying problem with a computer.

The BIOS wont post after it has been turned off and started again unless I turn the switch off/on on the power supply. The fans, cdrom hdd and everything starts running but the bios never beeps and the monitor stays black.

I HAVE TRIED: reinstalling windows xp, flashed bios to latest, cmos clear, new power supply, other hdd, new memory sticks, graphics card. I also removed the motherboard from the computer case and laid it on a cardboard box and only connected the PSU, RAM and CPU.

Other than this the computer works great but its annoying having to off/on the power supply switch before turning it on after its been off.

My guess is that the motherboard is faulty but I would just like to hear what you guys think.

Sorry for my english
