I have the same problem with a similar system (see my System Specs). Anything more than 2GB RAM causes problems in 64-bit Win 7 if you have the combination of an nVidia nForce4 motherboard and a SoundBlaster X-Fi card like Xtreme Music (I did not experience this problem in 64-bit Vista Ultimate with 6 GB RAM). See considerable discussion of this issue in the New X-Fi Win 7 Beta Drivers
thread, including a reference to a Creative article addressing one element of the problem, a design incompatibility re PCI Bus latency (a complicating factor, not the root problem IMO), starting here
. Most likely, some change in memory management and/or audio signal handling in Win 7 has exposed a problem that has existed since our systems were built.
Note, if your system RAM is currently >3 GB, the easiest way to test whether your RAM is triggering this problem is to run MSCONFIG in Administrator Mode to limit Maximum Memory to 2048 MB or 3072 MB (Boot tab, Advanced Options). P.P.S.
