Hi there, I have a sony sony vgn-ar49g laptop which i have had for about a year, today i turned it on and the screen had lines through it that moved up the screen, i was playing around with the video drivers the night before. Anyway now the computer does not boot at all, won't even boot in safemode. The lines are still there when the computer is turning on, not sure if i could have blown the 8600M GT video card. I have put in the Windows 7 CD and booted from it. However during the first half of the installation it pops up with a message saying ' can't find cd optical drive driver' ( Blu-Ray drive ) and the installation can't continue until i put in a CD which contains that driver, however i don't have any CD's with this laptop and i don't know what the models the drive as when i search the laptop model on the internet, it basically doesn't exist. This is a confusing one, how do i find out what model the drive is and where do i get the drivers for it? Is it possible to boot sony vaio recovery or something like that? Cheers in Advance.
