Installing Windows 7 and Starting Windows screen hangs

-Pentium 4 1.5Ghz
-Seagate Barracuda 7200.10 ST380215A 80GB 7200 RPM 2MB Cache IDE Ultra ATA100 / ATA-6 3.5" Internal Hard Drive -Bare Drive
-MS-6547 Vers:2.1 MSI motherboard
-SONY CD/DVD-ROM
-Kingston valueram kvr333x64c25k2/1g.

Is this rig going to work satisfactorily with W7, or would sticking to XP be a better plan?

Cheers,
Lee

I decided to stick with XP for now considering the motherboard's drivers won't be able to support an installation of Windows7. From doing a little more research, I also found out that the processor type I have is not fully compatible with the motherboard. The RAM was fine all along. I walked away with this issue learning a couple valuable lessons in the end. Once again, Thanks for your help, time and patience on this matter to you and Doug!
