Problem with counter strike

Hello,



I've got a new pc win7 64bit graphics card and after that I use my steam for cs I'm unable to open "options, find server" or anything all I am able to do is create new map and play with bots,



Also I can not change the mode of operation from normal to widescreen, because it is 20 + inch, and can not change my resolution.



So can anyone tell me what to do?

Please help.

Thanks!



I did not find the right solution from the Internet.
