blank white screen

after I play one game, I get a blank white screen when I try to play the second game. So I reboot my computer and it worked for one game only.
I need some help with problem.

I think this happens with everyone. I ussually reboot my computer since my task manager is broken and the ussually works but some one told me to do ctrl+alt+delete and then end all the winbolo processes. Hope this helps you. :D

if u look in the processes tab of the windows task manager u should see 2 winbolo exe's. if u kill the secound one it should clear the screen to normal and u dont have to even leave the game. give it a try next time. but make sure its the 2nd one, if u kill the first one then thats it and u will just get white screen again because the other exe is still running.
