Please help!

This is another abnormal functioning in a series of others.

Today when i booted my PC, the Welcome screen took a little longer to disappear and then, on the desktop there was nothing, absolutely nothing.

I'm using WinXP SP2, its never happened before.

I opened msconfig, to see two new processes,
process command
1) owjokuch rundll32.exe "C:\WINDOWS\system32\owjokuch.dll",s
2) wmjgenhj rundll32.exe "C:\WINDOWS\system32\wmjgenhj.dll",b

i disabled them, and after rebooting, i got the same problem.

Then, i tried starting the explorer.exe from the task manager. It starts, only to get terminated automatically.
