GPU issue with laptop?
I have a Toshiba satellite p 105 s6227 laptop (it's about 5 yrs old) I recently got a blank gray screen on bootup that was persistent and after bringing to a shop, they declared it a motherboard issue and told me it was junk. Being the persistent person that I am, I tried fixing it myself. I installed Windows 7 with an attached vga monitor and after rebooting, it worked fine without the attached monitor.
However, after using it for a few minutes and updating the drivers and installing Windows updates, I get a BSOD regarding nvlddk.says, which I narrowed down to an Nvidia issue. (The laptop has a GeForce go 7600) this comes up again every time the system is rebooted. I thought I could reinstall and skip all updates, but even after reinstalling multiple times, the system loads with a very reduced graphics (24 colors maybe) and vertical lines across the screen. This occurs with an XP install or Windows 7.
I was able to reinstall the first time with the graphics looking fine,I'm confused as to why they show garbled after reinstalling again. It's an integrated gpu, so attempts to re-seat it are not an option. Is the gpu/mobo screwed or is there a way I can get it to work without installing any drivers as I did before?
