Hello, I just got a newer computer than the one I'm  currently using. I ENCOUNTERED a problem when booting. My OLD computer is a:

Anaheim 2 MOBO
Intel Celeron 600 Mhz
15 Gb Seagate HDD
4 Gb Western Digital HDD
256 Mb Ram
Windows XP Professional

and my newer computer is

Dell Precision 330
Intel Pentium 4   1.5Ghz
384 Mb Ram
----No HDD-------
AGP graphics card (model UNKNOWN)

I decided to use my newer computer and just use my hard drive from my other computer on this computer. I set the BIOS to auto and at first everything worked well somewhat. As soon as it got to the windows xp LOADING screen I get a blue screen saying that windows has shut down to prevent damage to my computer and to check hardware like HDDs. I took out all the PCI CARDS but I can's seem to get around it. I dont understand if this can be fixed. or what can I do to fix it. I put the hard drive back on my old computer and it works just fine but it doesnt work on my new one any ideas? suggestions?

Anything is appreciated Thx. So did you attempt to reload Windows or just put a drive loaded with completely different hardware in the newer machine and expect it to run?You're going to have to reinstall Windows XP on the new machine.Ok I tried re installing windows but there was a nother problem. The computer won't boot to Cd drive even if set on the BIOS. I tried a startup disk i made on my old computer and I can get to DOS prompt. After that it doesn't detect my Cd Drive and I cant get into it to install windows. Im stuck What do I do now?You need a specific Windows XP boot-able disk. Find them on Microsoft.com
