blue screen of death

[damicmac]

I've just finished upgrading my old AMD Athlon with the following:
Epox EP-9NPA+Ultra mother board
AMD Athlon 64/3800+ dual core processor
Gigabyte GV-NX66T128VP mother board
2X 1Gig Patriot DDR SDRam
Antec 550W power supply

I'm still using my existing CD r/w and DVD player, and two Maxtor hard drives. Windows XP is installed on the 250Gig PATA drive. Everything seems to be working OK until the dreaded blue screen appears, telling me microsoft is kindly shutting down the startup. I don't recall exactly what it says, but to paraphrase I'm told to remove any new hard drives or hard drive controllers and/or to check for viruses. I have the hardrives set to cable select, with the main drive (w/OS) connected to black, and the slave connected to grey.
Does anybody have any ideas or suggestions?

That can be an expected reaction to when upgrading hardware. Sometimes an already existing Windows installation will take badly to new hardware right off the bat. Have you tried doing a repair install of the OS? That might help reload windows with the new hardware configuration. If worst comes to worst, you'll have to face yourself with a fresh windows installation.

I had about decided doing an OS repair was the next step since the hardware installation seems to be correct, but wanted some input first. Thanks for the advice.
