ATI2dvag Blue Screen

A computer changes the display modes and applies 16 bit colors automatically. An error appears saying the ATI Graphics has been stopped responding so you need to restart the computer. When restarted it shows ATI2dvag Blue Screen and the operating system fails to boot. You’ll be able to access your data from the Safe Mode and Normal Mode won’t work temporarily.

This is really a bothering problem especially when you’re playing games or doing some important work on your computer. Besides, it makes your data insecure and causes further damages to the PC. If you’re getting this problem and seeking a solution, you have come at the right place. Fortunately solving this problem has never been a hard task. Let’s begin.
  • Update your AGP Controller
  • Disable AGP FastWrite
  • Check and Clean System Configurations
  • Scan System Files

Update your AGP Controller
AGP stands for Accelerated Graphics Port. Its primary objective is to accelerate the 3D performance of your games and computer graphics.
If the AGP Controller is out-of-date you may receive ATI2dvag Blue Screen. Update it using Device Manager as discussed below:
  1. Click Start | All Programs | Accessories | System Tools | Run.
  2. Type DevMgmt.msc in the Open box and press ENTER.
  3. Right click your AGP Controller (For example, SiS AGP) and select Update option.
  4. Select automatic update option. If unsuccessful, try manual update option after downloading appropriate files from the manufacturer website.
  5. Restart your computer.
Disable AGP FastWrite Feature
Many motherboards support the AGP FastWrite feature. Although your motherboard is capable of using it and it is already enabled by default, it can be interfering with other programs and Windows components.  Thus disable it by performing the steps given below:
  1. Double click My Computer icon on your desktop.
  2. Open C:\Windows\System32\Drivers\Etc\Modules.d
  3. Right click the file NVIDIA and select Open With | Notepad. If the file name is other than NVIDIA then open concerning file.
  4. You’ll find the following line: options nvidia NVreg_EnableAGPFW=1 NVreg_EnableAGPSBA=1
  5. Replace 1 with 0 and save the settings by clicking File | Save.
  6. Close the file and restart your machine.
Note:In some cases you’ll have to alter the BIOS Settings to disable the said functionality. Please visit the website of motherboard manufacturer for detailed information.

Check and Clean System Configurations
The registry of your computer may contain certain strings & keys which are incorrectly modified by some programs. Scan the registry errors and clean them as soon as possible. Download a genuine Registry Cleaner such as PC Fresher. 
Scan System Files
Some of the operating system files can be missing or replaced by malicious programs. Scan them using System File Checker as below:
Running System File Checker using Command Prompt
  1. Click Start, point to All Programs | Accessories.
  2. Right click Command Prompt and select Run as Administrator option.
  3. Type SFC /SCANNOW and then press ENTER.
  4. When you’re done please restart your computer.
