I have a dell XPS desktop and new Nvidia geforce gtx 470 card. loads of ram and 50 gig of memory on hard drive. I bought Fallout three a week ago and i get install errors on first disc mainly to do with texture. The question is why will in not install properly? I have been back to GAME (store) and exchaged the discs for new ones. This has had no effect. Disc two will also not load?
Can any one help please.

Disk 2 has been known to not load. Try booting the PC into safe mode to resolve this problem and install the disk from there.
