Problems with my graphics card

[Pearce95]

hello,

My system is running with :

Windows 7 Home Premium (x64 bit)
AMD athlon II x2 250 Processor ( 2 CPU's ) 3.0 GHz
12GB of RAM
NVidia Geforce GT 430 - Graphics Card

The problem;

When im running a video on Youtube or some sort of 'Flashsite' my computer occationally makes a weird noise ( Threw the speakers ) and then my moniter goes in some sort of standby mode.

When the monitor comes back on the Video box is green with no picture but i can still hear the sound.

it also Disconnects my Wireless dongle.. ( Have to unplug it and then replug it for it to start working again )

When the problem occurs i get a error code: 4 come up.

Im not very good with computers and don't understand much of what to do or my to do with hardware a lot of it!

i was given some advise on speeding up the Speed of my graphics card fan speed ( but i have no idea how to do that ) and they said they were not sure if it was overheating or if its just F***ed and on its way out

Any advise would be much appreciated and Thanks for your time.

Regards
Oliver Pearce

I have checked out for the same and found a no of people facing the same error but then one having ASUS NVIDIA GeForce GT 430 has mentioned that the issue was solved after installing latest (9.2.0.439) Atheros driver, so just try out the same and see if it is helping.
