I had may HP laptop for about a year now when my display started showing vertical coloured lines and finally went blank. I took it to HP and they changed the display.
It worked fine for about 2 months and now after about 10 minutes on the screen starts to flicker.
What I mean is that the screen will go blank (black) and on again so fast that it looks like it flickers. Sometimes this will be a bit slower so that I very quickly see it go black and back on again. Like, it doesn't refresh fast enough. The refresh rate is 60Hertz which is the only option I get at 1440x900 pixels (17" screen) 32 bit.
Do you think it's a hardware problem again or could it be a virus? (although I have checked and I'm clean)
Thanx for any thoughts!
