Hi all,
Last week I was watching a movie on the laptop and all of a sudden the screen went all pixellated and jagged. Immediately did a reset and loaded up, however the display showed four streaks of the same pixellated feature shown before. I even resorted to re-installing the windows but did not fix the issue.
Loading OK on safe-mode (therefore assuming it is either a driver problem or hardware issue), uninstalled the driver and installed the most recent one. Still same issue on restart. Loaded again on safe-mode and disabled the driver then no issue.
Can you please assist?
My graphics card is "ATI Mobility Radeon HD4870" running on Alienware M17x R2. I take care of it religiously i.e. I rarely move it from my desk and even close the lid carefully.
Could it be that perhaps dust is causing the graphics card to loose it's contact with the main board? I was going to try and do a thorough cleaning tomorrow.
Many thanks in advance.
