HD 4830 3rd Party Drivers?

Recently I have been having all kinds of trouble running the games I normally play. I almost always get an APPCRASH c0000005 error. (give or take one or two zeros). I have checked everything, ram voltages, ram timings, set everything back to stock speeds and no luck whatsoever. I have messed with everything but my graphics card and I am pretty sure that is the problem because I just updated the driver software. I have been looking all over the place for some 3rd party drivers to test out but am having a pretty hard time finding them. Either they are CCC modifiers and not actual drivers, or they aren't for Vista 32. I have checked Omega, no go there either. I don't really know where to look! Does anybody know of some good 3rd party drivers for this thing?

OR, maybe a different solution to this problem? Thanks!

It's not a driver problem. Millions of people are using those drivers in vista without problems. Sounds like a hardware problem or conflict with old/nvidia drivers.
Sounds like you need to try a clean windows install.

just install the driver without the catalyst control center. CCC is generally what's gonna have problems with .net if anything and removing it generally gets rid of those annoying bugs. As zip said though, it would be best for you to go with a clean install.

Rivatuner.. obviously don't even think about overclocking until you have it stable.
