Driver problem with ATI 4870 and Vista64

hi,
I have a problem with my computer,I recently replaced my hard drives and installed ATI 4870 512 mb thus need to reinstall Vista, now I get the problem that does not solved.3D applications are immediately turn in to bluescreen or the computer freezes.In Windows, it happens frequently that the mouse pointer become 5 time larger than normal pointer size and then the computer freezes. So I reinstalled Vista and returning to the same problem.

hi,
As far as I can tell it's almost always a driver problem.Apart from the graphics driver what else have you changed recently?Make sure that your monitor is set to the primary display? video won't show on anything but primary.

you may just need to adjust your screen resolution:

System->Preferences->Screen Resolution.

Re: Driver problem with ATI 4870 and Vista64

There are many reasons why you might have a hardware or software driver problem. You might have installed an update that caused your driver to stop working. You might have installed some new hardware and not yet installed the necessary driver for that hardware, or the driver might be incompatible or corrupted.
