Blue Screen and WNT_5.1P

Hi - I've upgraded to vista and am getting the blue screen of death every 5
to 10 minutes. I really need some help -

1) how can I open the log to try and find out what my problem is? When I
try it tells me that I don't have access to the file. (I only have 1 account
- default admin...)

2) When I try to install an exe that I think will help I get "Does not
support this Operating System: WNT_5.1P" - this is a file from asus for my
motherboard for vista 32-bit...it should work! I've gotten the same error on
a few executables, why?

Thanks for any help, I'm very frustrated after 2 days of crash after crash
with no luck in troubleshooting.
