Those applications that tell you that you have to pay them in order for them to update your drivers are pure scam, again, drivers are FREE, you just got to take some time and find them so you can install them manually. You are still missing some options for the System specs (32 or 64bit win 7, audio?, etc) so I can't give you a specific link but I will give you the general link.
AMD Graphics Drivers & Software Here you can find your specific driver for video
If you have realtek audio, you can go here to download your driver...
Realtek from here you choose AC97 or HD
You may also have a SoundMax...
Sound Max Drivers & Downloads - Sound Max
Or finally, VIA drivers...
VIA Drivers Download - VIA Technologies, Inc.
Realtek are the most popular... unless of course you have a dedicated sound card, then you must go to their website.
Google CCleaner and download it on a Temp Folder that you can get to it later (install it immediately after saving it), save the drivers on this folder as well. Go to Control Panel/Programs and Features and Uninstall your game completely, also your Audio and Video drivers but do not restart yet, do so after the last driver is uninstalled.
Restart but go to Safe Mode instead of normal desktop, pressing F8 after post usually does the trick but this will depend on your Bios. Once at safe mode, open up CCleaner and run the Cleaner and then run the Registry cleaner as well.
Restart, once you get to the desktop, give it a few minutes because wind 7 will install the generic drivers for Audio and Video, it is ok to let it happen. If it asks you to restart, go ahead and do so. Once you are back, get to the folder you salved the drivers and Right Click on one of the .exe files (uncompress first if you got a zip or rar file), as soon as you Right Click on it, use "Run as Administrator" and install the driver completely, do not restart if ask... do the same (exactly the same) with the other driver, once that is done, restart and restart again if and when prompt. Now install the game in Custom mode so you get to choose or have more options, if the game asks you to install DirectX, let it do so and whatever else it needs to install, do not interfere with the installation in any way. READ BEFORE PRESSING THE ok OR cancel BUTTONS.
This should take care of your drivers and game install... hopefully, you'll be able to play now.
If this game is an older game (Pre Win 7), if you rUn through the same issue AFTER doing the above, then go to the .exe file and run it in compatibility mode, it may do the trick.
