white screen, can't see anything

Dear support,

On startup, all I get is a blank white screen. I can't see anything.

But, I can plug in a monitor and do everything else just fine.

I tried twiddling the drivers, but maybe I did it wrong or overlooked the right one(s). I tried a system restore, but that threw an error on restart.

I even dove in with my screwdriver to make sure no plugs got knocked loose (don't worry, warranties were long voided).

Please help.

thanks~
