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?

Took the laptop to the store where I bought it from since it was still under warranty.. Apparently there was a fault with the monitor, had it replaced.

Your problem could be related to this question Dell laptop weird display after hard reboot.

Nvidia now releases updated drivers to the public. You don't have to go through the manufacturer anymore.

I would check to make sure you have a current driver.

If that doesn't help you may have a bad or failing video card.
