ATI2Dvag.dll is an extremely important file on your system, which has been designed for use with the ATI Graphics Drivers which are extremely common on the Internet. Although this driver & file is extremely important for the smooth operation of your system, the fact is that it’s continually being damaged & corrupted – leading your PC to run extremely slowly and with errors as a result. The errors this file causes will often be shown on a blue screen, and will continually stop you from using your PC at all.
The way to fix this problem is to first reboot your damaged PC into “Safe Mode With Networking”. This mode is something Microsoft introduced to help you control various problems & issues that Windows has in a reliable environment. It basically loads up your PC without any software / drivers running, allowing you to perform much needed maintenance or upgrades. To do this, restart your computer and before Windows even starts to load, press F8 continually. This will load up the boot menu, where you should then pick “Safe Mode With Networking” to load up your system. When in this mode, you should first uninstall any ATI graphics drivers that are on your PC and then install the latest version of the driver from the ATI website. When this is complete, restart your Pc into “normal” mode.
On top of that, it’s also advisable that you repair any errors which may be inside the “registry” database of your computer. This database is a central storage facility for all the settings and options Windows requires to run, and is consequently being used 100’s of times each time you use your PC. Unfortunately, this part of Windows will continually become corrupted, leading your computer to run much slower and with a lot of errors. To ensure this problem does not cause your ATI2Dvag.dll error, you should
use a registry cleaner program to fix any potential errors it has.
