Antman, is there any software that might detect it? Otherwise do you think running sfc at the cmd prompt would fix the DLL problem (assuming it is a DLL).
Edit: I'll run TASKLIST command when it happens again.
SFC won't hurt (a healthy machine), so there's little reason not to try it.
The point of TASKLIST is to check whether the problem is specific to the Task Manager, in which case it's some sort of less serious UI issue or simple corruption, or whether all attempts to enumerate the process list, including those which have nothing to do with the Task Manager, all end up concluding that there are no processes to show.
If it's the latter - TASKLIST is also devoid of process names - then you should consider the very real possibility that the machine has been rootkitted. Either way, please make sure you've got backups of your data, and treat those backups as infected until you get to the bottom of this.
