Weird crash when playing games

[Scorch1994]

Hello, sometimes when I'm playing games, the pc freezes and the screen turns into a bunch of squares with 2 random colors, or the screen will start flashing random colors.

Videos of screen flashing
Dishonored
Skyrim

In Dishonored, the crash only happens when I go to where the crosshair is on this image.
I'm playing with 1900x1200 resolution, and I tried some different resolutions and at the lowest resoultion possible (800x600) the game doesn't crash.


My laptops specs:
gtx 260m
Intel Core2 Duo P9700 2.80GHz
4 GB RAM

Are you expecting more from this laptop than it can do?

I've played games that are more demanding with no problems before, but the screen flashing is something that's started happening only recently.

Is the laptop over-heating?

Post any minidumps by going to C:\windows\minidump. Minidump files have a .dmp extension. Select all the .dmp files. Right-click sending the files to a compressed(zipped)folder. Upload that folder as a file here

Here's the minidumps. When playing games the temperature is usually around 70-75[FONT=sans-serif]°C[/FONT]

Are you over-clocking. The minidumps point to general Windows instability with an Nvidia driver issue. Is Windows fully updated, running Windows Update manually including all optional updates

I haven't overclocked. I have the latest driver for my graphics card and I'm going to install all the optional updates in Windows Update right now.

Okay, let us know how it goes...

 

[Scorch1994]

Nothing changed.

Replace the video card
