Hi all,just joined,im quite new to the pc world and still learning!!

my problem is this-

i have installed on my pc-

COD 5 which plays gr8,graphics/sound awsome

Halo 2 plays gr8 even though i think the grafics for this are poor

Team fortress-steam,plays gr8!! no problems with any of the games above.

these games for some reason crash my pc....
some start off ok then freeze,or the colour distorts from a white screen/dark bule/black....some times i can still here audio but the game play stops or the pc goes back to the desk top.
the games are as follows-
Battle field bad company 2
Gears of war
Crysis-this plaedy gr8 almost right up to the end of the game then no more

My spec-

You really should have no bother playing any of these games except Gears Of War which can be a pain,see this link.click here. I have got all the other games bar Crysis and can play without any bother.
Are the games fully patched?
Graphics card drivers up to date?

Adding a second card in SLI would not help with your problem the one you have is fine

Looking at your specs you have 8Gb RAM installed but only 3.25Gb useable because you have the 32 bit version of Windows 7. If you are able to upgrade to the 64 bit version you would be able to make full use of your 8Gb. At the moment you are not making the optimum use of what you have available.
