There are a few things to do. Check your hardware manager that there is no yellow exclamation or questionmark, if so, disable it.
Upon bootup hit F8 key. Displays booting options. Either go to "Last known good" or "vga safemode."
Once you are in, highlight with mouse "My Computer", right-mouse click, properties, advanced, performance options, Virtual memory manager, change. You should have about 1.5 times your physical memory free hard disk space. (eg 512meg physical memory, reserve about 750meg of HDD).
If you can get in either, shut-down and reboot.
Another thing is to boot with your 2000 CD and do a manual repair", to check bad files. Have your Emergency Repair disk ready, if dont have, "locate" do a search. Good luck.
