CoD 4 menu problem

[Zanussa]

Hi,

i'm new to this forum so sorry i place this one wrong.

i bought CoD4 2 days ago, installed it, and played it perfect.
I do not meet the system requirements with my video card, i played it yesterday the whole day and i'm running it on 'NVIDIA GeForce 6150SE nForce 430'.(updated it already, didnt work) It shocked me it worked and went smooth.
I went online, and had no probleme playing Multiplayer.

Now, today... when i start CoD MP and SP, i get a strange screen of gray lines... (looks like some saws running through my screen)
Any1 knows this problem and know a sollution? I realy want to play it since i know my pc can run it.
