Ok I thought it was my video card problem when I started my DFI LANPARTY PRO875 motherboard. I bought four sticks of PC3700 Dual channel 256mb memory. Now I recieved my Radeon 9800 256mb and it didnt come on. I switched the ram with a stick of 512mb PC2100 and the monitor actually came on. I guess I cant use this memory with this . I dont know what I am going to do with the memory. Does anyone know the problem or anything? I am going to order two sticks of Crosair XMS 512mb PC3500 today. Also I switched my hard drive over and all right and used the pc2100 ram, and whenever it trys to load windows, the whole computer just auto-restarts. Its rubbishrubbishrubbishrubbishty, can anyone help me please!
