Couter Strike Source Problem! NEED HELP!!

i have a problem with my CCS. when playing the image will get distorted similar to it being warped. any ideas on whats the problem?

 

just an image or the entire game? did you try reinstalling the game or checking the gfx drivers?

 

sometimes the gun or sometimes the background. (something similar to this:

 

first i looked at it i thought it was a over hang
thers mostlikely a problem with the map dose it only do this on this map? or every one and if its a modded map then...

 

that map was dust2 original, however it happens and every map or server i play. sometimes it a lot distortion and sometimes its only minor. still its enough to put u off. and on top of that i use wireless connection and so i lag like bitch!

 

thats a no no unless you have a gaming router.. that there might be your problem..

 

i have a belkin wireless G+ MINO router. and i have never had this problem b4. bin playing CSS for 6 months now and only recently i have bin getting problems like this
