Have you had frequent and unpredictable WOT client crashes? If you have a sound card and nVidia card (maybe ATI too) then follow the instructions below to see if it solves your problem:
FYI:This solution assumes you have a standalone soundcard and is not using your onboard soundcard.
Go to Control Panel and then Device Manager and locate the Display Adapter and look if you have an entry for 'High Definition Audio Controller'
Do the same for the 'High Definition Audio Controller'
IF the BUS used is identical (between the video card and the HD Audio Controller) BUT the FUNCTION is different (say PCI BUS 1, Function 0 and PCI BUS 1, Function 1)
'DISABLE' the 'High Definition Audio Controller'
Your WOT client would be much more stable. It might still crash but not as often. The problem stems from sharing the same bus (IRQ in fact) hence they interrupt each other. The reason is most video cards today do have their own audio device built-in for HDMI output.
UPDATE: For newer video cards specially nVidia the location of the HD Audio Controller has changed.
It is no longer under the 'Sound,Video and Game Controllers section' (although sometimes it is still listed there, you cannot disable it there anymore).
You must now go to the System Devices section to DISABLE it.
UPDATE II: I would also check the python log. If your python log contains a lot of missing file error, inability to read .pyc files and countless CTD (Crash to Desktop) during the game as well and have PATCH Launcher errors like "Critical Errors' , then you might have a Hard Drive problem. You might not notice this with other programs but with WOT you will. Sadly the solution for this is a brand new hard drive. This I know from experience as well.
Please comment here and give tips and observation if this helped you.
Edit: This has also been tested by people with ATI video card and the same fix works. You just might have a different designation for your 'HD audio controller'.
You can also try to DISABLE, "Data Execution Prevention':
If you also have ONBOARD video and added a video card please DISABLE the ONBOARD VGA in the BIOS to prevent any IRQ conflicts or video driver conflicts.
Also try to run the WOT application as 'Administrator' seems to help so right click the client executable and do a 'Run as Administrator'
Running STANDARD vs IMPROVED graphics settings also might mitigate your crashing and this goes the same for running a non-HD client as well.
Also if you are in a 32-bit OS and have 4GB, you can try to run this application (LARGE ADDRESS AWARE) to solve client crashes,freezing and loading issues:
Keep in mind that this would not work in 64-bit OS.
You can also try to set your WOT client.executable to 'Windows7 or Windows 8 compatibility' and see if it becomes more stable by right clicking the Properties of the World_of_Tanks.exe.
Something new to try:
1. go to your WOT folder and find the wotlauncher.exe
2. Create a shortcut and paste it somewhere you can find it. "right click" on the new shortcut and go to properties.
3. Alter the target to add " -integrity_default_client" after the target (notice the space after .exe and before -integrity)
4. Run the shortcut and the client will check your game. Hopefully it will find missing/corrupt content and replace it.
PS: You might have to DISABLE the HD Audio Controller for every time you install new video drivers since that sometimes resets the Device Manager settings.
