Re: advice laptop
If it is heat related it would be nothing to do with dust.. More than likely a dry joint on the GFX board or if a sub board possibly corrosion on the connectors. Prolonged heat will cause the joint to move and create problems..
A few question for the OP is are the lines
1#Are the lines on the bios screen or is there any other corruption on the bios screen?
2#Are the line visible from the start of the desktop being loaded 3#or do they appear after a time.
If yes to the 1# then it's hardware problem if though no to that question and yes to 2# then it's probably a driver issue but if part 3# is relevant then it's again hardware..
