blank white screen problem

hi, my problem is that every once in a while my screen just goes blank, and its a really bright white color, i can hear everything in the background like games or messaging, but i cant see anything. im not sure if its a problem with my monitor or just my computer. i tried updating my drivers but it doesnt seem like it did anything. PLEASE HELP! THIS IS REALLY ANNOYING AND IM TYPING REALLY FAST INCASE IT TURNS WHITE AGAIN!

 

bump--and;
seems like one to MOVE to the hardware forum, likely a Monitor issue. But it won't hurt for you to run these tools free from links below... adaware/spybot/spyware blaster, in the meantime while you wait for further analysis in this forum.
