New video card keeps crashing and have to reinstall driver


Sep 16, 2011
I just bought a new Biostar TA75A motherboard with an AMD A8 3850 processor. Also, brand new 8 gig of ram, new hard drive and optical drive so the machine is mostly new. Upon startup, the desktop was giant and was scrolling regardless of how the resolution was set. There was NO driver on the disc for the video (built in ATI Radeon 6550). I went to the website and installed the driver which temporarily fixed the problem. The machine keeps crashing and when it reboots, the driver is gone and I have to reinstall it because the desktop is huge again.

How can all of these brand new elements that were sold to me together on account of their compatibility be having so many issues?
