GPU problem after cleaning laptop cooling system
Hi,
Today I disassembled my Toshiba Satellite L500 laptop (windows 8.1 64 bit) to clean the cooling mechanism. I cleaned the cooling fins in front of the cooling fan by blowing with my mouth, and using a vacuum cleaner at about 15 cm away from the fins. A lot of dust had built up in the 5 years I used it extensively.
When I put everything back together an error occurred: VIDEO_TDR_FAILURE (atikmpag.sys). A couple of reboots ended up in the BIOS I think. Another problem is that my screen now shows a lot of artifacts, as can be seen in the pictures attached. I didn't have these problems before, this is solely a result of the disassembly of my laptop.
I managed to boot into safe mode, and deleted the drivers of the video card. This allowed me to boot the laptop in normal mode. During the installation of new video card drivers the laptop crashed a few times, showing the BSOD with the error again. Installing new drivers solved the BSOD problems, for now.
However I still have the artifacts on my screen. It consists of alternating vertical bars that work, and show artifacts.
I assume the video card is dying. At first I thought it may be due to a bad connection, but after reconnecting all connectors again nothing changed. Maybe the vaccuum cleaner build up enough static electricity to fry the video card, but that's just an educated guess. Is there anything I can do to fix this?
I attached the necessary debug files, and two pictures of my screen.
The video card I have is an AMD ATI Radeon Mobility HD4650.
Thanks in advance!
