I have a used Asus P5k SE motherboard that I bought off an online auction site and assembled all the parts with a brand new 1 gig PCIe graphics card and 4 gigs of ram. Both of the RAM sticks are identical in specifications, but different in appearance. After I turned on the power switch nothing appeared on the screen. I don't know if the graphics card is faulty or like the guy said when I bought the motherboard that the BIOS chip is faulty. Also, the power supply reboots by itself but only once. Assuming the BIOS chip is faulty, how would I fix it or would I have to buy a new BIOS chip? I believe it is a AMI BIOS, where would I get a replacement chip from if the BIOS chip needs to be replaced? And, how much would I expect to pay for a new BIOS chip?
