I'm kind of at a loss as to what wrong. I've had this PC for almost 4 years and its been working well until yesterday. When I tried to boot it up the power came on and I heard the drives start and the CPU fans began to turn but then nothing. The screen is blank and and the Q-code only displays 00 and the PC would just stay in that state until I shut it off. After I plugged a USB stick into one of its ports it shut off and then back on and would continue doing that unless I manually shut it off. Now without the USB plugged in it will only stay on for about 5 seconds and then shut off and then turn back on in about 3 seconds over and over until I turn it off The manual for the motherboard states that 00 is not used but when I called the Asus tech support they said that 00 means that something is wrong with the CPU or CPU socket. I haven't taken it apart yet to make sure that the CPU pins and socket are all together but as far as I'm aware nothing has happened between the last time my PC was on and when it stopped working. So I'm a little perplexed that that could even be a problem. Anyone have any advice? Thanks for your time.
