ATI 9800 Pro trouble

As soon as I log in 8/10 times I would get either VPU recovery error, or Blue Screen of Death.
I used Omega version of Catalyst 4.9 drivers.
The VS .NET was is an "old" problem. I experienced it with Catalyst 4.7, Omega version of 4.7 and Omega version of 4.9 drivers.

I installed 4.3 Catalyst drivers. It stoped crashing right after log in. I could even open new project in VS .NET without a problem. Then restart later, when I tried to create a new project File/New Project.
If I remember correctly there was a restart before it, when the screen just turned of. The screen went black, but few seconds later it came back and it did display a New Project window. Although graphics on some of the applications like Zone Alarm and ASUS PC Probe were a bit messed up. Restart later when I tried to create new project in VS .NET it went back to crashing, displaying blue screen of death and saying that infinite loop message.
I then decided to install Control Panel. As soon as I restarted it went back to crashing right after log in, with those VPU recovery errors. After I disable VPU recovery and turned of fast write, it booted up normally. Still crashes when I try to start a new project in VS.NET. I think the problem is with VPU recovery.
I don't know could my MB driver be to blame? I installed 3in1 drivers from ASUS website and AGP Drivers (aka miniport drivers), from AMD website.
I think I can uninstall AGP Drivers just by going to Add/Remove programs, but how can I uinstall 3in1 drivers? Also how do I reinstall default Windows XP drivers. I heard they work just fine with my old MB.
I have ASUS A7m266 MB.

I have a similar problem when I switch users on Win XP Home. About 1 out of 5 times you switch users, the screen goes black and about 2 minutes later I get a blue screen stating that the driver is stuck in an endless loop. I believe the driver is ativ2ga (or something similar). I sent an e-mail to ATi tech support. I received an automated reply stating my configuration must be incorrect and pointing me to useless tech support pages. This has occured on 4.7, 4.8 and 4.9.

Pretty much same experience here. Only it happens on 4.3 too. I think the log in one is the problem with their VPU recovery. The problem is VS .NET is with their "stable" drivers.

You need to put your ram and video card back to stock speeds. OC ram is one of the main causes of your problem.
