I have a computer that was running a 915pbl intel mother board which recently just stopped working. It would start then when I let go of the button it would die. Then it would just flash when I pressed again on, off, on, off. I have replaced the processor, video card, power supply and kept the dvd roms and hdds in. The same tower as well. Nothing is working no matter what I buy. Now, I turn it on, and it is running on the p5vd2-x mother board with the e6420 core 2 duo processor, it just stays on with no boot up. I have never had this before. I have tried getting help from the best and they are baffled. I now turn to you for help please let me know if you have any solutions?
