Hi Guys
Just started an updrade this morning,

P4P800 delux, P4 3.2, Ge-force Fx, 2*512 ddr2700.

All went well apart from I'm getting no post, no beeps! and I can't power down the system.

Disconnected all devices just to see if it was trying to boot from another device other than the BIOS, no luck, changed the graphics card, cleared the cmos. I think the problem is the power supply, it's only 300 watts, another 500watts is on the way. Also this could be another factor click here

After considering these issues, do they relate to the system not being able to power down or restart? Also I have tried all possible panel connector configurations, reset plug etc..

Do you have the 4 pin 12V power attached as well? It looks like half an AT power supply and goes on as well as the standard ATX one. I think you need a "Pentium 4" power supply to have this connector.

That's all I can think of at the moment and it's taken from the link to the Asus website. You said that whatever is in that link "might be a factor" - is this what you meant?

Sorry if it's stating the obvious a bit.

Here are a few other things you could try: make sure the memory is in firmly, and just try it with the most basic components; mobo, cpu &fan, memory, graphics card, keyboard & monitor.

I've discovered on this forum that it's not necessarily just the wattage of the PSU, but its efficiency, although I doubt your 300W one is a P4 power supply.

Forgot to put "a few" things. I've had problems even getting a computer to come on because I had a faulty case. This was because the case was a really cheap and nasty one, and I found that it would work out of the case, but whenever it was in the case, the power supply would cut out.
