I just installed Windows 2000 last week. It's a dual-boot os with Windows 98SE. I do have 2000 on a separate partition operating under compressed NTFS. But for the last 3-4 days my computer has been locking up. Everytime when I leave it for awhile I come back and can't do anything. No cntl-alt-delete, no nothing. I have to do a hard boot. I ran defrag, norton utilities and still cannot figure out what it is. I know it must be some sort of conflict. I'm using a Logitech scroll mouse with updated drivers for 2000. I have a feeling it has something to do with the mouse. Please help. I need to run 2000 for my business.
