My computer started freezing and wouldn't respond to anything but a hard reset. Now it will not boot. There is no post beeps, and I've done a few steps. I have tried out each one of my ram sticks one at a time, removed video card all to no post or boot. I noticed my hard drive did not spin at all during any of my trouble shooting steps. All fans came on but no hard drive spinning. I finally got around to removing my CPU and the hard drive started spinning, put CPU back in and no hard drive spin. Tested two hard drives same results both time. I'm running an Asus M3A motherboard with an AMD phenom x3. So is it my CPU or is it a bad mobo?
