Help!!! with Windows ME reinstall

When I purchased my PC, I had Windows ME. Later I upgraded it to Windows XP
professional 2002 (Service pack 2). A couple of days ago, my PC crashed. So I
thought of using the recovery CD's that came with the PC when I bought it. It
seems that I have successfully re-installed Windows ME and after I took out
the recovery CD from the CD ROM drive, it rebooted (as it had instructed me).
After rebooting, it is stuck on the very first screen (black screen) where it
shows the PCI device listing....
I had thought that once ME is reinstalled and the PC reboos, I'll upgrade it
to XP professional (since I only have the upgrade CD of XP professional)
Can someone please help....
