Windows 7 - Video Driver conflict?

I have just assembled a Tiger Direct barebones kit with Win 7 64 bit home premium.
ASUS motherboard with onboard ATI graphics, and a Radeon HD 4350 graphics card to boost graphics performance. The machine tends to shut down with a BSOD which provides this error message.

I can't access the two help files--not sure what to use to open the .dmp file--I don't see a Windows 7 version of software to open than, and while I am the administrator for the machine under my own login, I'm told I don't have admin rights and need permission to open the file. I reviewed the permissions and don't see any more I can have, so I'm perplexed.

At the same time, my tech friends suggest my problem is likely to be a driver conflict between the onboard and the video card and I should work on resolving this. When I check DM the Radeon video card shows no conflicts and says it's working correctly. In the meantime, my digital monitor works on the analog video outputs both from the motherboard and the graphics card, but neither DVI output works. I've got the latest available drivers for the Radeon card and the Windows 7 check for Samsung drivers says the PnP driver is the latest available. Samsung shows no new drivers for Windows 7.

I'm feeling pretty good about getting everything working so far, so if I can master this last glitch in my first assembly project I'll be thankful for the help.
