I recently put together the following computer:
Asus A7N8x-x mboard
AMD 3200+ chip
Corsair 400MHz 512MB ram
Antec 350W power supply
ATI 9800 pro video card
Windows XP
After several errors when running the computer at 400MHz FSB, I finally got my board and ram replaced from the companies. This has fixed the random lockups due to running at 400 MHz (computer would run fine at 200MHz fsb). However, now I cannot get programs to load and run properly. Windows runs fine, no lockups, but if I try to run a game (Prince of Persia demo, for example), the computer will run the game startup fine, then lock to a blue screen after the game starts. Sometimes it will then give an error message, with 'dumping physical memory'. What might be causing this problem?
