Hi jp17315, possibly a bad driver update, driver/s conflict or worse case scenario a malware infection.
Couple of options for you to try, hopefully the 1st one will resolve the issue as it is more straight forward;
How To Fix ati2dvag.dll Errors
Step 1 – Update Your ATI Display Drivers
It is always imperative to maintain your ATI drivers to the highest possible version. ATI are continually releasing new drivers to deal with problems and to improve performance, and the ati2dvag.dll error can arise from drivers being outdated. If you are going to install new drivers, you will need to restart in “Safe Mode with Networking”. This prevents the corrupt driver from loading and causing the blue screen half way through your session. To do this:
» Restart your PC, or turn it on, and past the BIOS splash screen, press F8.
» A menu will appear with various choices for your Windows boot. Choose the option “Safe Mode With Networking“. (It has to have networking so we can download the file)
» Once it has loaded, open up your preferred Internet browser.
» Navigate to this ATI download site.
» Fill out the form to suit your system’s requirements.
» Download the file, install the drivers, restarting when prompted.
» You can now start your PC normally after the drivers have updated.
Over time, the drivers for your graphics card can become outdated and cause conflict with newer software present on your PC. This is what causes the blue screens, so always make sure that your software is updated to the most recent version to maintain system integrity.
Step 2 – Manually Replace ATI2dvag.dll On Your System
Replacing the ati2dvag.dll file is probably the surest way to get your system running as smoothly as possible again. You can do this very easily by following the guide below:
1) Download ati2dvag.zip from our server here http://www.personalc...ors-on-your-pc/
2) Unzip the ati2dvag.dll file onto your computer’s hard drive
3) Browse to c:\Windows\System32
4) Locate the current ati2dvag.dll on your system
5) Rename the current ati2dvag.dll to odbc32BACKUP.dll
6) Copy & paste the new ati2dvag.dll into C:\Windows\System32
7) Click Start > Run (Or search”run” on Vista & Win7)
8 ) Type “cmd” in the box that appears
9) Type “regsvr32 ati2dvag.dll” on the black screen
10) Press enter
This will replace the ati2dvag.dll file on your PC with a fresh, new copy that your PC should be able to access again.
If you suspect your system may have a malware issue I suggest you check out the self help guide at the malware forum http://www.geekstogo...cleaning-guide/
if after following the guide you believe your system may still be infected you need to start a new topic there and not post any malware logs on this forum as they are not used here, provide them with a link to this thread to show them what if any steps have been taken. Once you get the all clear from the malware guys if the issue is not resolved return here and someone will assist you.
