I've had some system related issues today, which I had to do an archive and install of the OS again to get past. Now Parallels seems to have some issues. When I start the VM I get the rotating window effect and see a few lines of DOS, the usual Windows startup thing, but then the Windows window becomes solid black, and it stays that way. Checking with Activity Monitor shows that Parallels is using over 100 percent of the CPU (this is on a Core 2 Duo MBP), and trying to do a Sample shows this message: "sample cannot examine process 511 for unknown reasons, even though it appears to exist." I'll leave my machine on overnight, to see if Parallels gets finished with whatever it is that needs so much CPU. Is there anything I can check while it's doing its thing, to help figure out what is going on?
