Oops! My laptop, Compaq Presario R3230, is not working now (just worked yesterday evening), blue screen, hangs at disk checking...when I reboot with safe mode, it still hangs at is multi(0)disk(0)rdisk(0)partition(1)\windows\system32\drivers\atisgkaf.sys, I guess there is something wrong with my video driver, but how can I fix that problem without wipe out my documents in harddriver?

I am trying to google by it, it seems some guys also got that problem, some steps are suggested:

1. ?Insert the QuickRestore CD into the CD drive and restart the
? ? system.
2. ?When the red Compaq logo appears, press and hold the Caps
? ? Lock key. ?Next screen will be a blinking QuickRestore screen.
3. ?When the QuickRestore text stops blinking, press and hold the
? ? Num Lock key.

but where can I get QuickRestore CD? included CD seems not in my room any more...anybody has thought about that?
