Hi,

I was trying to fix this issue at the weekend... the screen resolution was way too large and the actual display was also bad - grainy colours etc.

The resolution was on max. By updating the driver of the graphics card I managed to resolve the issue. After rebooting the display was back to normal. Job done, I thought.

However after 10 mins or so the original problem had returned (no reboot or anything, just left it logged in to windows and no one touched it)

I did the same fix and again the problem came back.

Does anyone have any idea as to what is most likely to be causing this?

It's an old machine, 6 years or so and it's not mine so I can't quickly test stuff. (Windows 7)

Thanks,

Shaun
 
Could be corrupt drivers or files, maybe a virus but I have not heard of a virus messing with the video display. Could be a failing video card.

Try removing the video card from Device Manager, reboot, have it detect it again.

Re-installing Windows fully if that has not been done in a while is a good idea.
