Whis it's not running normally

[Riff masteR]

Hi, i watched most of you're videos, especially about the speccy video. I have played Counter Strike about 4-5 years now and it's running normally, the servers i play on don't have lag etc. Few days ago I bought a new monitor and when I open the game it says that it can't run in OpenGL and puts itself on Software. When I turn it back on OpenGL it switches again to Software. Can you help me ? I will put my system things down and monitor things I would be happy if you help me

Hi Riff masteR   

I assume the problem only happens when playing Counter Strike or other games? If that is the case then lower the game resolution a bit. Then see if you can play the game without any problems.
