Throughout the game, it freezes in random spots to the point where I have to bring up the task manager to shut it down. It is the regular/old version of Fallout 3 that I just installed on my newly built desktop a week ago. I also downloaded all 5 of the DLCs but haven't initiated any of the DLC quests.
My system specs are:
Intel i7-920 quadcore processor
ASUS P6TD Deluxe motherboard
Thermaltake Frio cooler
Four 2GB sticks of DDR3 Kingston RAM set in Dual-Channel for a total of 8Gbs
Western Digital 600GB Sata Velociraptor HDD
Plextor 24X optical drive
Geforce GTX460 GPU with 1GB of V-Ram
Windows 7 64bit full retail version
ESET Smart Security 4
I run Fraps in the background
I omitted some of the specs since I doubt it would be related to my PSU, case, etc.
