Qosmio X505-Q893 - Possible GPU failure? URGENT

This is urgent, today I've gotten loads of sudden black screens followed by a "Display driver crashed" message. I've tried clean installs of current and past Geforce drivers, with no difference. There are now strange effects showing up, for instance right now my window borders are purple (the screen just flashed, the driver crashed again and the windows are back to normal). I'm also getting flickering and sometimes windows don't maximize completely (only text fields show up, for example)

I don't seem to have any data loss, and I can still use the PC, temps are totally normal...is my GPU failing? I haven't done any recent upgrades, the only thing I can think of is Firefox 16 installed yesterday/today.

Help!

 

First thing I would do is check with an external display. This will ensure if it's the chipset/GPU or lcd screen that is displaying the weird colors/artifacts. If it looks ok on the external, then most likely <strike>chipset/GPU</strike>. I MEANT TO SAY IT'S MOST LIKLEY NOT THE GPU/CHIPSET. If external comes back ok, then it will be a LCD issue.


It could also likely be a driver issue. Try doing a completely driver removal; here's a thread regarding how to perform one [although I've never tried it before]: http://forum.notebookreview.com/gaming-software-graphics-cards/611371-tutorial-how-install-remove-amd-nvidia-drivers-using-clean-method.html

If the driver removal doesn't work, then I would backup everything and do a Factory Install on your computer [use your Toshiba Recovery Disks]. If it is a driver/software[firefox] issue, that should eliminate it.

If no one else is able to respond, I can move this thread to the gaming(graphics cards) subforums.


Good luck and keep us posted.
