Windows 7 becomes unresponsive on startup

[alhanelem]

Lately Ive been having trouble using windows 7. Every time i start it up normally it will load to the desktop but then suddenly become unresponsive
and then the desktop turns white (like when a window stops responding) then i have to hard reset.
Right now im running on Win XP (i use it as a backup OS, thank god) and it works fine.

Ive tried resetting the bios back to default - nothing
Ive tried testing testing with only one stick of ram on BOTH sticks - nothing
Ive tried uninstalling some of the updates that were installed before this all happened - nothing

does anyone know how i can fix this? (hopefully not reinstalling Win 7 because that will take me all day to backup, reinstall win 7 and all of my programs/games)

Check event viewer to see if any errors have been reported...

It doesn't become usable at any point?

The first thing to try is to see if you can boot in safe mode, if you can then take a look at event viewer. If you can’t boot in safe mode try a system restore to a time that it worked by using the Windows 7 boot disk repair option.
