Nothing but the sound of the fan when I turn on. Checked PSU and all voltages output correctly. All connections to motherboard OK. I tried disconnecting everything from motherboard except CPU. Turned on and expected "beeps" to indicate system searching for the absent RAM but no sound. With memory back in and drives connected I turned on with Norton Ghost boot disk in floppy. Normally there would be quite a bit of noise as program was loading but now nothing. I guess either the CPU or motherboard is faulty. I removed battery to clear CMOS but that did not help. At least I know the internal speaker that gives out the beeps works as I got a lot when I turned on without the battery in place.

Any ideas anyone?

TIA

Sounds to me like

mobo = alive because you are getting beeps when no battery is used
memory = ?
cpu = probably dead

I would pop your cpu out, and take it to a small Computer shop or a friends house to try it out. Then you know for sure.

But my guess would be it IS the motherboard, just because when you took the RAM out there were no beeps. I only know this becuase it happened to me with my old motherboard.(although that was a socket A board). CPU was fine for me, and mobo was dead.

If you weren't overclocking and nothing unusual (power glitch, static shock, etc) occurred prior to the failure, you might want to check your power connectors. You may measure good voltages at the connector, but the problem may present itself in delivering the power from the connector(s)

It's much more likely something mechanical failed (like a connector) than the CPU. If you can, measure voltages on the mobo...there should be some power test points somewhere that will let you know that power is getting from the PSU to the components on the mobo. It's fairly simple and certainly easier than first pulling the CPU.

As you're looking at voltages, you might consider a crude check for ripple as well by using the AC setting on your meter. Some PSUs don't shut down when ripple takes them outside the spec'd voltage limits, yet the ripple present can prevent the computer from functioning properly.

Thanks to all who replied. I will have to learn how to check the voltages on the motherboard.

I have been looking at motherboards and CPUs for sale today. Most of the motherboards I saw advertised were micro ATX and my case is just plain ATX. Just out of interest, is it possible to fit a micro ATX motherboard into the larger case?
