a really weird error.
recently a laptop given to me was overheting so i did what i sually do and took it apart and put new thermal compund on it.... after i did this i installed windows 7 and all was fine.
i then proceeded to install windows 7 drivers for the graphics card and the graphics went all distorted in the top left like a box and lies etc, it does this even with external display.
i have replaced thermal compund with thermal pads now and this does not solve the trick, bare in mind that before i replaced the compound the machine worked 100%
i have installed 3 different versions of win 7 and all do this at driver stage including the factory restore!
what could be the problem?
the machine is:
Acer Aspire 5542g
ATI Radeon 4200HD
Athlon II X2M300
thanks in advance
