I just bought a brand new Dell. I am haveing problems playing many games. For example, Hitman Blood money is not compatable with my video card. In Freedom Fighter,s I cant get past level two because when I complete the level the game locks up. ALso the screen gets bright as soon as I hit a speciic sopt on level two in the game. Further more I get weird sounds on level two. One of the background sound seems to cut in and out on the level. Another game I played wont even get past the loading movie. Anyone have any idea wihats up? The computer is brand new and it does not have any viruses or spywear on it.

I have 2.4 GHz. Intel Celeron
512 MB RAM
80 gig HD
XP Home SP2
Intel Extreme Graphics 2 graphics card (64 MB virtual memory).
SoundMAX intergrated digital audio card.
