IT Queries: Computer problems answered

Hi My home computer has decided to shut itself down after a few minutes of running.  It comes up with a blue screen stating an error in NV4-disp.
The screen goes like it is disentagrating – very small coloured squared running down the screen in approx 10cm columns.  I did try to ring last week on the evening show on the ABC but alas could not get through.    Thank you for any help.

The problem is with your video card which is an NVidia brand (hence the NV4). From the description it is overheating.

Modern video cards usually have a fan to keep the processing unit cool. What has probably happened is the fan has either failed or become clogged up with dust.

Either way, it’s best to have a chat with your local computer tech to see what they can do to fix it.
