Thank's for your reply dude, my graphics card is an ATI HD RADEON HD 2600, i allway's get the driver's from the ATI website, when i turn my pc on, when windows 7 start's and the part what say's welcome, there's a big red flash just before my desktop comes on, it wasnt doing that when i had xp pro or vista on, it was the same driver's what i downloaded as well, i cant think what it is.
