|Looks like your computer has a 945GM chipset. A very good chipset IMHO. If you have done your windows update lately you should have the newest graphics driver installed. Most of the problems with artifacts on the display is due to memory issues. So, flip your computer over, with the computer off and the battery out. Remove both sticks of ram, pushing the retainer clips on the sides of the ram. |
Now just incert one stick back into the computer and test it from there.
Also, you want to make sure that your system fan is clean of any dust.
