try moving the display sliders to the right a bit in FS.

IF those are your computers specs, then you have a very powerful processor which is let down by a (i dnt mean to be rude) rubbish integrated graphics system – i.e. you don’t have a graphics card as such – what you have is a graphics chip which is on your computers motherboard (if you know what that is). i would suggest looking into getting a new graphics card, and adding more RAM – an extra 256 Mb would be good.

also, you will need to find out for sure if your computer does indeed have an Intel extreme graphics chip. if it doesn’t, and it has a separate graphics card, then it may be that the Intel Extreme graphics drivers that your bro installed shouldn’t be there. i.e. wrong software for wrong hardware. try and find out what graphics card/chip the computer really is using. if it is something like an Nvidia or ATi card, then the Intel Extreme Graphics thing shouldn’t be there. if it is an Nvidia or ATi card, then download the correct drivers for the card.

i hope u can understand my babble, and i hope that helps.

EDIT – thinking about it, Dells do not tend to come with graphics cards – so it probably is an Intel Extreme Graphics chip that it uses.
go on to the Intel website, and download the latest drivers for the Intel Extreme Graphics
