I have 2 New Abit SG-72 Motherboards, that will not boot up, it is to much
of a
coincidence that both might be Faulty, so I must be doing something wrong.
I have tried 3 CPU's, 3 Sticks Of memory, and used both the On-board
Graphics, and two different AGP Graphics cards ,and still the same problem.

I have tried Clearing the CMOS for One Minute with the ATX Power lead, and
the Battery removed.

The machine powers up but nothing on the Monitor.

Can someone help please, I am now getting desperate!

If You don't hear any beep codes I suspect that AGP is not contact firmly in his junction.
Don't screw it to chasis, try to push firmly and "swing" it in junction. If AGP card doesn't contact in junction
the screen remains black and no beep codes and no boot-up.
The second thought is :
If You connected CPU cooler to other FAN junction than this which is dedicated for CPU,
the mainboard will not power up at all becouce of FAN-FAIL but I think that it is not your problem.

I have just purchased this motherboard with a similar problem. only
mine will not boot up until I have reset the CMOS on the JP1 switch on
the motherboard. the problem is the computer then boots up fine but
half way through the Windows Installation when the software reboots it
will not start again until I have cleared the cmos again from the
motherboard. If you know what is wrong before I take the motherboard
back I will be please to hear from you.
