hi , im running windows xp home editon with sp 2 with IE 9 ( I think ' it has multi tab browsing )
my problem is this , my laptop backlight keeps going on and off and also my pc keeps switching resolutions , the back light problem surfaced a few weeks back but it only occurred the once. But since i connected my pc to the tv it goes off for hours at a time but periodically comes back on ' sometimes only for a few seconds or minutes and on the odd occasion for a few hours ' whilst im using the tv as a monitor the resolution switches back and forth from 800 - 600 to 1024 - 600 and sometimes to a even higher resolution , then it switches back ' sometimes it does it many many times but at the moment it hasnt changed for at least an hour . Can anybody give me some guidance as to what the problem is ?
many thanks
