Is my motherboard dead?

Try unplugging the PSU for a few minutes. If that doesn't work, remove the battery and reset the CMOS jumper while unplugged. CMOS jumper reset explained in the MB manual.

Just reset the CMOS jumper. Discharging the board by unplugging it from the wall will likely reset the CMOS . No need to buy a Gigdud MB when an eighteen year old makes an unsolicitated statement like, "when I first started working on computers...." Don't feed the nOObs. This forum is becoming beseiged by them.

If you pulled all the system RAM and a working speaker is attached to the MB speaker header and is capable of sounding BIOS beeps and no beep is heard signifying there is no RAM in the system, the problem is a bad processor or MB. If you have another known working CPU try it.

I think it is the CPU. About eight months ago I assembled a brand new MB and CPU, both new from the retailer. The system ran perfect for maybe three or four days then had the same symptoms as your system. Would not boot or post and no beeps when the RAM was removed. I was certain it was the MB. Not possible for a CPU that new to fail, right. I contacted the MB distributor and asked for an RMA. Their support person asked a few questions and one of the questions was, had I tried a different CPU. I had not, but I told him I had one and would try it and get back to him. I couldn't believe my eyes when the system fired right up after installing a different CPU. So, it is possible the CPU failed even thoughit is only four or five months old.

The CPU is only actually 6 weeks old? looked at the day i got it! The odd thing is that there is a blue RAM light that lights up to indicate if the ram is in but when its removed it still lights up? that seems very odd?

ya im going there today bloody frustrating ill post the results thanks for your help very much appreciated.
