Well yes, MacDrive8+ will override and disable Apple's crappy HFS driver.
MacDrive is said to work now but had trouble when Windows 7 came out.
Paragon has their own HFS9 as well as NTFS driver.
NTFS does not like filenames with special characters, forced me to go through and rename or remove a lot of files when I started using Vista.
Otherwise Windows DVD has memtest, and definitely run chkdsk on Windows (with attempt map out bad sectors).
I doubt system file checker will find anything but worth running (admin) command
sfc /scannow
Pull your HFS drives as a test if you can
I recommend Paragon Clone OS to make bootable clone of Windows, easy to do on Mac Pro where Windows is on its own drive. Not only is it a great backup but will tell you if it encountered an error during the clone.
And it could be your graphic card or driver or another that you installed. Hopefully your log and other forum would help point out what is in the dump.
