i recently upgrading from AVG Anti-Virus Version 7.5 to 8.0 the installation was a success but the problem i've been having is quite strange. the problem appears to happen when i enter a Server and download a Map then try to fully connect and enter. the game crashes and comes up with an error Internal driver error in IDirect3DDevice9::Present(). though it's connected with DirectX some users say it's likely due to AVG somehow. i don't know but i think AVG maybe scanning a file or something as some advanced user have said. they say uninstall AVG and go with AVAST! or AntiVir. i am a big fan of AVG and AVAST! i have used both in the past. now that i am playing CSS(Counter:Strike Source) i keep coming up with this error. i have tried replacing my Video Card and placing it back in, reinstalling both Omega ATI Drivers and ATI Drivers and nothing seems to work. can't be my card as it runs fine. the error doesn't happen all the time but it does happen now and then. i have also tried updating DirectX and still... nothing. please, if you have any advice please give it to me. Thanks!
