My PC runs fine with no problems whatsoever, but whenever I try to play Medal of Honour Pacific Assault or Doom 3 the game either crashes or the window just shuts down altogether. My PC meets the requirements for the games as my system is as follows: - Windows XP Pro SP2 Epox 8RDA+ Motherboard Athlon 2500+ CPU 2 x 512Mb PC3200 (PC400) DDR Memory ATI Radeon 9200 I did originally have my memory installed in DIMMs 1 & 3, but changed this as the manual says they should be in DIMMs 2 & 3 for 2 sticks of 64-bit memory, however the outcome is still the same. Can putting my memory in the wrong DIMMs have damaged my motherboard? I have run Memtest86 on each memory stick and no errors were seen. Event viewer does have events for when the game crashes, but there is no description to the event, which doesn't help much. Does anyone have any ideas?
