I just bought a new Dell Inspiron 530. I installed Call of Duty 4 on it and anytime I try to run it I get the blue screen message PAGE_FAULT_IN_NONPAGED_AREA with 0x00000050. I'm using Windows XP Home and have a 128MB Radeon HD 2400 Pro Video card. All the drivers are up to date and the computer meets all the minimum specs. I'm not that technically advanced and I have no idea how to fix this. If anyone has any ideas, I could really use the help!
