Hello
Ive seen so many people having problems with steam so tell you a few things which normaly work for me.
Delete ClientRegistry.blob located in C:\Program Files\Valve\Steam
Delete platform.gcf Located in C:\Program Files\Valve\Steam\Steamapps\
If your CS has got really laggy or your keys have been messed with delete your config.cfg then you will have to bind all your buttons again in options. Some nasty admin might of slow hacked you.
Also try searching in steam supprt section:
