ATI drivers won't install/blue screens during gaming

Hello, recently, when playing any games within about 5-10min the game would hang, with shredded graphics and lines everywhere, would go to an unreadable bluescreen and then restart. I would get a "Blue Screen" error or a "LiveKernelEvent". Also there was a BC COde 116 mentioned, in the small dialogue box that would appear after every crash (can't remember where to look up the little screen at the moment sorry). I updated bios, and driver, reinstalled vista, bought different RAM but nothing has helped. It was only today, that I realised the graphics driver's don't seem to have updated. I uninstalled them, used driver sweeper, and the installed the new ones downloaded from ati's website, but it still shows up as the old version afterwards. So my questions are, how do I install the new driver? And is this the solution for my bluescreening during gaming? What could be the other possible causes? Thanks very much in advance.

Specs:
phenom2 x3 720 2.8ghz
4gb ddr3 133mhz crucial ram
M4A78T-E mobo (790gx chipset)
HD 3300 gpu intergrated (waiting on the 5000)
vista business x64 sp2

Thanks for the reply. I already did that, use drivercleaner I mean. Where can I check to make sure they are absolutly gone? I check the device manager and it doesn't show up there, but, when I reboot (after having uninstalled them) I do not get a "new hardware detected" message, which makes me think something is still there, even after using drivercleaner?

Well I checked in display adapters, and all it had there was the defaut windows one. And yes, my moniter went back to the default res. However, I still can only install the 8.650 driver, not the 9.9 I downloaded, and I don't even know if this will fix the root problem, namely, windows crashing while gaming and giving me a BC Code 116 + LiveKernelEvent/BlueScreen error.

Exactly, and I assume that my bsod's are as a result of that somehow. I've also been considering, maybe the there's a fault with the actual hardware of the hd3300 somehow? I have two days still to rma it. Thanks for your time helping me here, by the way, it's much appreciated .

I couldn't find anything specific, though a mod did post something about the X86 and or X64 versions of the C++ 2005 redistributable, and to update them to fix some problems with the vista drivers [http://forums.amd.com/game/messageview.cfm?catid=279&threadid=107672&enterthread=y]. Should I go ahead and try this?

It sounds like many are having that same problem and are waiting for a solution from ATI.

It may be time to get ahold of ATIs support line to see if they've come up with a fix yet.
