Win2k startup problem

Hi, I'm running Windows2000 on a laptop (IBM Thinkpad).

Starting yesterday, whenever I start Windows (whether
normally or in safemode), I get stuck with a blank desktop
after the starting windows, and logon to Windows screen.

I tried bringing up the task manager with Ctrl+Alt+Delete,
and in the Processes List, I noticed that these 3 programs
keep showing up by rotation:
"ntry.exe", "javavs32.exe" and "sysvr32.exe"

At any one time, there'd be at least 2 copies of each,
they disappear immediately and a new one show up soon
after, thus I cannot use "End Process" to stop them.

since I'm still stuck at the blank desktop, with no
startmenu, I can't run any virus scanner either.

The computer was working fine the day before it happened, but I have been having intermitten browser-hijack problems.

Does anyone know how to fix it?

Thank you very much.

For the moment, let's copy from repair folder. as I wrote here:

If it works, go to Spywareforum.

Thread moved.

Thanks, managed to get it back to the way it was
(i.e. fully functioning except browser still hijacked, but at least I can start copying out all the important data files)
