The first you'll have to do is diagnosis the problem, you can try a few step here,
1. remove all plugin that are not used while rebooting such as Harddisk drive, disc drive/rom and floppy disk.
2. try to reboot, if it not work, turn off again.
3. unplug the DDR, clean the pin with contact cleaner spray then plug in again. do same thing with the CPU/processor.
4. if it nort work too, you need to check your power supply.
hopefully this helps.!

The one long beep, this has something to do with the video card.
Can't really tell without the BIOS you are using !
Anyway, try removing the card and replace it. ( with anything, just to check. )
This is a good board, I have a ASUS P4C800 and you can't beet it.
P.S. Make sure all your memory is the same freq. and clock speed.
Good luck.

No booting

The problem is Operating systems are co-dependent on hardware.
If the motherboards, processors, ram, video adapters, etc don't match you would not be able to swap hard drives and expect to boot.

You could try pressing F8 on boot and try to access safemode.

If it does boot into safemode immediately it will want to reactivate windows.(because of all the hardware changes.

If it still can't boot, you may want to put the 80 gig in as slave to the 40gig and ghost the 40 gg hard drive over to the 80.

If you don't want to lose your data on the 80 gig then reboot with an xppro cd and reinstall windows in the same partition overlaying the installation on top of existing windows directory.

the new windows will have to be activated but all data will still be there.

I'm sorry to say that I had much the same problem with a RMA'ed mobo from Asus. The one that came back worked for a short time, and then died.

I can't say that Asus is the only one I've had the same problem with, Intel has done the same. But I kinda expected more from Asus. I did not bother again, I just decided to do a mobo/CPU/memory upgrade at Fry's.

Can not get any boot at all

Hi, First of all, your hard drive is what this computer needs to boot up. Try to see if you can POST, that is, only plug in power supply to motherboard with cpu and memory in there. Don't put any hard drive or other device into motherboard as yet. see if it reaches past post. If it does, then plug in hard drive and see if the problem occurs again. If it does, then the problem is the hard drive. But for now try reaching past post with only the bare necessary components for startup. Then let me know what happens.
