I have a Toshiba Satellite A355d running Vista 64 bit that I have had for over two years now. The other day I was working on a 3D graphics program called Blender, and all of the sudden my screen went gray. Everything looked like it was still running, but the only thing I could do is cold reboot by holding down the power button. After rebooting everything ran fine for about 5 minutes then it went to a gray screen with blue vertical lines. It now does this consistently. I have reinstalled the video driver and it doesnt seem to help. I also ran it in safe mode to run a virus scan with AVG, and uninstalled some game mods that I recently downloaded for Sims 3. When running in safe mode it will run forever with no problem. I also restored my computer settings back to a previous restore point, and that still did nothing. Any suggestions?? From what I can find Toshiba has not put out a Vista update for my video card since right after I bought the computer. I am sure it could really use one, but it seems as though they have given up on the Vista drivers and only update the ones for Windows 7. Here are some of the specs for my computer:
Processor: AMD Turion x2 Core RM-72
Display Adapter: ATI Radeon 3100 driver version 8.522.0.0 7/31/2008

Moved from Vista to internal Hardware.
