I have an Intel i7 860 2.8Ghz installed on the GA-P55A-UD5 motherboard it was working fine until yesterday, I made a BIOS change and used the PC for couple of hours, powered it of, but when I tried to start it up a few hours later, it turns off after a couple of seconds, restarts, turns off, etc. without getting to the BIOS screen.
I have performed the following tests:
1. Pressed the clear CMOS button
2. Removed the battery for an hour
3. Disconnected all other hardware, HDD, DVD-RW, etc.
4. Tried different graphics card
5. Tried different power supply
All of the above made no difference, still reboots before BIOS. The only things left connected are the Power Supply, Motherboard, CPU, RAM and Graphics card.
The are no beeps from the motherboard. The lights shown are:
1. MD1 and MD2 light up then turn off just before reboot
2. GD1 and GD2 light up but stay on until reboot
3. CPU light lights up and stays on until reboot
4. All the Phase LED lights are on until reboot
Any help would be appreciated.
