Once you get it working change your config file to read me only so servers can't bind things for you.

And should I just delete the whole steam folder?

No, just delete your current corrupt 'cstrike' folder. It will make a new one once you re-install.
If you did the default installation, the cstrike folder directory is:
C:\Program Files (x86)\Steam\SteamApps\common\Half-Life\cstrike
