It's my first time building an intel computer and I was wondering which mobo (socket 775) I should buy. So far I have a C2D E6400, eVGA 7900GS graphics card, Seagate Barracuda 320GB sata hard drive, and a Cooler Master 600W power supply. I tried using an Asus P5B-E and after i installed the latest BIOS it would not post. I did a CMOS reset but it didn't fix anything so I had to RMA it. Does anyone have a suggestion for a good mobo. Also, what kind of memory should i get for it? I tried Corsiar TWIN2X2048-6400C4 but the computer kept restarting randomly.
