I have a dell inspiron 1520 with a nvidia GeForce 8600M GT video card. I have Windows 7 professional as an operating system.
Yesterday when I was using it the screen started to somewhat flicker then go completely black. I restarted it and in the boot screen everything seems fine, when I entered the login screen it became flickery again, and when I logged in, when a couple of windows popped up it went black again. I hooked it up to a tft monitor and the monitor works fine, and did some more tests that confirmed that under higher graphics causes the laptop monitor to go black.
Is there a reason why this is happening?
