I have problem with my laptop dell inspiron 1520. Screen sometimes goes black and with artifacts PC freezes. My guess is that I overheated my video card. I hope someone cold give me advise what would be best action to do.
I've Nvidia GeForce 8400M GS
with full Nvidia drivers I can't watch movies. But by removing main files: nvd3dum and nvwgh2um I can watch movies and play games that uses VGA. I can use windows normally just when I use internet explorer and when I with mouse fast forward big document from top to bottom or opposite I get black screen and white, yellow, green, blue dot box in place of mouse cursor. PC freezes and I have to use hard reboot.
Reinstalling windows/drivers doesn't help.
It's most likely that 3D acceleration doesn't work (broke).
I would like to know is it software or hardware issue?
