OK so what you're gunna want to do is POST. This stands for power on self test. All you want is to test the CPU, motherboard, ram and psu. Do not have anything else plugged in. If it still doesn't work, you know that it is one of these things. Try each RAM stick individually, and plug in a monitor to see if you can get into BIOS. Check the clock speed to make sure the RAM is working right. If this still doesn't work let me know.
