First off, assuming this page is still correct: Compatibility & Upgrade Information
... PT is only supported on Vista 32
Was 7.4 running OK for you on the same machine, OS, etc?
That possibly answered, depending on how you reverted to 7.4 from 8, it's possible
all the components, registry settings, etc, were not
returned all to the actual 7.4 state.

Yup, time to get serious.
That's like playing tag in a mine field.
Boom ....you're it.
Well, we've already apparently determined that the problem may well be that Vista 64
is not supported by Pro Tools 8, regardless of hardware.
But, while I generally will argue against
using a large vendor general purpose machine, instead arguing for building or having built a machine designed and optimized for audio, it remains that large numbers of people get audio work done on PT HD, LE, and other systems on Dells, and Sonys, and HPs, etc. In fact, my (non PT) recording machine is a Dell refurb that cost me $344 ($404 to the door with shpping and exorbitant Cali sales tax). I stuck some extra RAM and HDDs in it, but it's been a great machine. Not a rocket ship but quiet and dependable -- and surprisingly powerful, considering I originally bought it just as a utility server. I do
keep my machine well optimized.
PS... When I saw this thread title, I bet myself that plug ins were probably involved. Of course, now that we know that Vista 64 isn't officially supported, we're left wondering where and how many problems there may actually be.
I think at this point, I'd get on the DUC and see what I could find out. I saw a few threads when I did a quick googling for this issue.
