OK - my PC is powering up the motherboard, CD & hard drives, however nothing appears on the screen...

Ive tried swapping memory around to see if that makes any difference, in doing that I thought I'd see what would happen with no memory, strangley the BIOS does not beep to alert me to that fact which would suggest its not checking the memory on the POST test...

Could this be a dead CMOS battery? - not sure as the PC was working fine before with no signs of any deterioration of the battery before that.

Either way I need to find a way to get my PC working again - right now ive run out of ideas, especially as it doesnt seem to care whether the memory is present or not!!!

1. Reseat everything. PC cards, RAM, processor.

2. Test your power supply

3. Test with a different motherboard if able

4. test with a different proc if able.

I'm fairly certain youve got either a bad board or bad proc based on experience

The fact of no beeps shows that the system is not completing the POST process.

On an ATX system, the CMOS battery should not make a difference. Still, you can check it by simply removing the battery. You may also want to try resetting the CMOS.

Remove all plug-in cards and see if the system now posts.

While you have the cards out, inspect the motherboard for damaged or burnt components.

If all looks good, the Power Supply, CPU and mother board are still potential suspects.
