The usual symptoms of the ati2dvag problem are:
- PC crashes without warning, sometimes the display shows weird patterns before the crash.
- Resolution may revert to the lowest resolution settings upon restarting your PC.
- The CPU temperature may shoot up prior to crashing.
- PC may not be able to reboot back after the crash, unless you turn off the power supply unit of your PC and switch it back on again.
- Your PC tells you (sometimes only) that the ati2dvag driver has failed to function.
This is a universal problem afflicting thousands of PCs worldwide and can occur in totally new or old computers; it doesn’t discriminate. Imagine the frustration of buying a new PC only to have it crash on you after a few weeks and thereafter.
There have been many hypothesis’ postulated. Some say it is a very stealthy virus, some say it is an incompatibility with Windows XP SP2 and ATI, some say it is a problem with the hardware acceleration settings in the ATI graphic card, others say it is a problem within Windows XP itself…etc.
The 2 most common “solutions” are:
- Reinstall the ATI driver. You are advised to launch Windows in Safe Mode (press F8 before Windows boots), go to Windows Add/Remove programs and uninstall everything ATI. Remove the DAO/MDAC component as well. You can use the ATI removal tool utility which can be downloaded from the ATI website. The complete set of instructions on removing ATI can be found on the ATI website.
- Go to System Devices in My Computer > Properties > Hardware, and locate the option, PCI standard PCI-to-PCI bridge. This could under other names on your PC, so contact your PC vendor if you’re unsure. Right click, and select the “update driver” option. Manually search and install the PCI standard PCI-to-PCI bridge.
