Was this that 64-bit version that was causing problems for you previously? I recommend turning Driver
Verifier back on again to check things out.
Btw, I'm not sure the last time you ran Driver Verifier that you were aware of what it does. DV does not perform any tests and therefore doesn't give any 'results' or 'errors' as you mentioned before. Instead, all it does it make Windows more willing to panic (BSOD) in the event of a driver bug. Therefore the best way to use DV would be to set it all up, restart the system, then use the system normally until it crashes, then provide us the crashdump (or if it boot loops go into Safe Mode and turn off DV then send us crashdumps). The crashdumps generated by DV are more likely to provide us a solid answer than those without.
Also, to confirm DV actually is 'running', after you've restarted from setting it up - provided it isn't already boot looping - then go back into DV and select 'Display existing settings
'. It should list drivers
and checks that are enabled.
