Alright first things first my motherboard is a Gigabyte GA-7n400 Pro2 and my DDR slots are set up like this II II II II. If I set my 2 Ultra 512MB 400MHz PC3200 in the two same color slots (orange, DDR1 and DDR3, or, Grey, DDR2 and DDR4) My computer wont even start up, and just make a constant beeping noise. Now they both do work if I them in separate colors. The computer does read the both of them, but the only problem is when I play a game, like F.E.A.R, or Doom 3, actually any game. the game will actually shutdown within a 1 minute to 5 minute range. or if im burning a disc it will shutdown random during the process. can anyone tell me what i can do to fix this. I have looked everywheres. :unch:
