John,

Now that you've said that it was working fine and just suddenly started this behavior, there is one issue that comes to mind readily.

I recommend that you do a disk defrag of the c: drive, whether the Windoze defrag reports that it does not have to be done at this time or not. They never thought about the kind of disk work we do with music files and fragmented bbw.exe and realtrack files have been known to produce exactly the symptoms you report.

Often a good idea to start Defrag at night and go to bed, because it may take awhile. Defrag can be set to power the computer down when done, or you can just leave it on and let it go to screensaver or whatever.

There's a better defrag available than the one inside Windoze, it is called "Defraggler" from Piriform, free download version. I recommend it.

For reasons of safety, only download it from the official site, I'll post a hotlink here, just hit the 'download' button on that page and then install it. Pretty self-xplanatory as to use.

Note: Also a good idea to check the drives involved by way of the Hardware Manager screen found in System -> Control Panel and make sure that none of the drives have reverted to the dreaded PIO (Processor Input/Output) control rather than DMA.
