I have an Asus V8440 ti 4400 graphics card ( which hasn't worked properly since I bought the PC ). The latest problem is that the card will function with the standard windows vga drivers but not any nvidia drivers. If I install the drivers all I get is a flickering mess on my monitor and have to go into safe or vga mode to uninstall them. The pc vendor is looking to wash their hands of the problem saying the warranty has run out on the PC.The PC was returned to them ( actually the warranty agents ) for 2 months ??##** and then just the graphics card for a further 3 months !!##**. I am 99% convinced that the card is faulty but wondered if anyone here has any ideas. Thanks.
