Toshiba Satellite L50A BSOD and Driver Problems

Hi,

I own a Toshiba Satellite L50A Laptop, and have had it for around 9 months. (Specs: http://www.mytoshiba.com.au/products.../pskl6a-013004)

For the first 6 months the laptop ran almost perfectly. Around Febuary though I started getting problems such as BSODs and the message "Display Driver stopped responding and has recovered, usually when playing games. I tried updating the display drivers and even restoring the system back using the Windows System Restore feature, and this worked for periods, however these problems kept coming back.

Finally last Friday I had 6 BSODs, all with different problems, and the Display Driver message now appears even just when I login to the Laptop. Also, sometimes when programs are running or even the screensaver, coloured pixels will appear on the screen and freeze up the program as seen in the first screenshot: https://dl.dropboxusercontent.com/u/...reenshots.docx

I've attached the minidump files for the Friday here: https://dl.dropboxusercontent.com/u/.../Minidumps.zip

I really don't know what to do anymore, and any help would me very much appreciated.
