Hi,

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

windows vista.

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?

Here is the link to the latest driver for your Dell video card, if after installing these drivers you still have issues with your card you may consider that your video card is not functioning properly.

Thanks I have tried that.

So it looks like hardware issue? At least my laptop works but not so well.

It may be the card itself that is damaged or overheating (have you tried to clean any dust that might have accumulated).

or it might be just the connection between the video and your screen, on laptops those connections often get loose over time.

or it might be your screen itself, did you try your vga output to connect a separate screen to it and verify if you still have the same issues.
