I have a problem w/my computer I was wondering if anyone could help me with. It's a Dell inspiron 9300.I have had it for 3 1/2 years.recently the screen started to fuck up,one minute it's fine,then you'll start to see thin lines come across the screen and it blurs out/shadow images stuff,but it only happens on the left side of the screen,the right side looks perfect still.It's real inconsistant also some days it only does it once,other days it's constantly,and it will go back to normal sometimes,other times I have to shut it down for it to go back to normal.any ideas?
