How to troubleshoot: is the problem video card or drivers?

I have a computer with an AMD "A" series CPU/GPU. After a couple of years, I started seeing video problems which made me think video card degradation or overheating - but of course, I had no video "card" that I could inspect or clean.

I gave up and bought a cheap video card (Zotac GRForce 210), installed it, and it has been working fine for about 6 months. Now, I am getting pixelation and strange window layering artifacts - some freezes and Blue Screen Of Death (BSOD - its a Windows XP OS) - a memory dump screen that said there was an infinite loop in NV4_disp (which I figured had to be a file in the nVidia drivers. So, I went online, and downloaded their fancy schmancy "GEForce Experience" application that looks for, finds, and installs new drivers when available.

Now, after a reboot, I no longer have the exact same video card/driver problems, now I'm just seeing random pixelation noise randomly dispersed over the screen - mostly when I'm online. This happens sometimes when I'm not doing anything (maybe their is an auto refresh) and with tab changes, drop down menus, with pop up menus and screens.

Something obviously is wrong... So, how do I troubleshoot whether it is the drivers or the card? Seems really odd the APU's GPU would have problems, and then a video card would have video problems. Anyone have any ideas what to do? I hate to waste money on yet another video card, if that isn't really the problem.
