I upgraded my RAM about 14 days ago and my computer ran just fine for 8 days and then it suddenly started turning on and off on a 1 second interval. I took everything out, cleaned off the dust, and took out the motherboard battery for a while so the MOBO woul reset and upon reassembly, the computer would boot, but I would run into the "loading operating system ..." That won't go away. I update the BIOS from p67aud7b3 f2 to p67aud7b3 f7 and now it still goes to the "loading operating system screen ..." But I can't even get to my BIOS settings or POST. This is very frustrating and I have done everything other forums with similar problems told me to do with no luck. Please help!
MOBO: p67a-ud7-b3 with f7 BIOS version
Current RAM: 4x 8GB or ripjaws Z 1600 MHz. (32GB total)
Old RAM: 2x 4GB ripjaws 2133 MHz (8GB total)
CPU: intel i7 2600K
GPU: 2x radeon HD 6970s in crossfire
PSU: corsair AX1200 Gold
Edit: I can now get to all of my BIOS settings. That was caused by a faulty keyboard, but I still cannot boot.
