Well, amazingly it actually works! I was able to activate windows over the phone and so far so good, no stability problems. Its just like how it was before the new mb and cpu. Just need to reactivate some programs and it seems ill be set. Didn't need to transfer my files after all. The only thing that ive noticed wrong is that the cpu is only running at 1.6ghz not 2.4 and that the ram is only running at 400mhz not 800. But apart from that everything is running smoothly. Temperatures are low with the cpu running at only 29 degrees. I still cant believe this is working without any issues what so ever. My old mb was an asrock 4coreDuelVISTA with an pentium D 805. I just want to say thanks to you all for the very helpful fast responses. Ill be sure to check back here in the future.

Ah ok. but what I dont get is why I was able to boot this xp home disk on my old dell but not on this one. Could it not be booting because I have xp pro already installed? Or maybe something is not connected right/wrong bios setting? I just don't have the time or money to be buying a new xp disk. But It looks like I might not have a choice.

Yes, it is the 1st boot device. Its is listed as the Primary IDE Slave. When I bought the pc with it came without an XP Disk, and only have the activation key for it. I thought that I would need to find xp on a disk so I would be able to re-install it with the new Motherboard. I found an old XP home disk that came with one of my previous machines, ive tested it on an older pc that has xp pro. It successfully booted from the bios. So I don't understand why its not booting on my build pc. It doesn't seem to be the original CD as its just a white disk that says XP HOME AUTO in black writing, but it seems to be genuine. Would it be possible to do a repair installation with this disk?

Great news, It turns out that the problem was down to a faulty VGA cable. Replaced it with another and everything seems to be working well. Only one problem is left now, I just cant seem to boot my new windows xp from the CD. Just keeps trying loading the old os from left in the hard drive that worked with the previous Motherboard. It actually gets as far as wanting me to activate it. Would that work? I read that its unlikely to get it to work at all, or would be very unstable due to compatibility issues with the new MB. But if it were possible it would save me time to re-transfer all my old files back. I have the activation code but no CD. If not then I need to find out why my current xp disk will not boot up.

I did all what you said, swapped everything around and cleaned everything. This time i'm only getting one fast beep, then nothing. The manual told me that one short beep is indecateing that the keyboard is not being detected. That cant be right as ive tested two keyboards and they light up and I am able to use capslock. What should I do now? I am really confused now, I have no idea whats wrong.

Yeah, just as I thought. Hmmm, no I don't think it comes with integrated graphics. http://www.asus.com/Motherboards/Intel_Socket_775/P5N72T_Premium/#specifications I don't think I have any other card to test, plenty of APGs but no pci cards. I have some other DDR2 memory I could test but It has something like 400mhz, I doubt it would work on this board as I think it requires a minimum of 667mhz.

Yeah, its secure. Ive even tried seating it in other slots. How can know exactly what Bios I have If I cant even boot it up to check? Would it be in the manual? I have it here: http://static.highspeedbackbone.net/pdf/e3853_p5n72-t_premium.pdf

Hi wolf, Thanks for the quick reply. I think the make of the bios is SST (well thats what it says on the chip). It starts of with 1 extended beep followed by 3 smaller ones.

Hi, I have just finished installing a new Motherboard and cpu, but when I powered it up I am getting nothing but beeping. I checked the Manual and it is indicating that no VGA was detected. These are the components: MB: ASUS P5N72-T Premium CPU: Intel® Core™2 Quad Processor Q6600GO HD: 160GB Samsung S166 SATA GPU: NVIDIA® GeForce® 9500 GT 1GB RAM: Integral 2GB DDR2-800 DIMM PSU: Storm 500W It was working fine in the old MB. Ive tried the card in the two other pci slots, still no luck. Also cleared the cmos via jumper and have taken the battery out for 30 minutes. Any ideas? Thanks
