How to fix a PC with a faulty graphics card

How to deal with: 'Graphics card not responding'

QUESTION I suspect my five-year-old PC has a faulty graphics card, which produces various error messages and freeze-ups. The most frequent errors reported are 'Driver stuck in infinite loop file ATIdvag' and 'Graphics card not responding'.

I thought the problem may be due to a corrupt driver, but the same behaviour is evident in Safe mode (which uses only Windows' generic drivers). Is it worth buying a new card or am I now stuck with onboard graphics? Jim Bennett

HELPROOM ANSWER You could buy an inexpensive graphics card, such as ATI's Radeon HD 5350. This costs about £30 online. Alternatively, you can enable your processor's onboard graphics by removing the existing graphics card and connecting your monitor to the onboard graphics output, or by setting it as the preferred graphics card output in the Bios.
