Yesterday my computer was working perfectly, today when I tried to boot it up from sleep mode, it started beeping and would not even get to the P55 LE screen or even the windows loading screen. Nothing, just blank screen.
I have tried shutting down and booting up about 12 times now. I've tried CMOS reset, unplugging PSU, reseating RAM, and testing each with a single stick in memory slot 1.
The debug LED shows codes 68, d4, d5, and 34. In that order. Once it gets to 34 it stays there and then starts a steady succession of beeps. It's like "beep...beep...beep...beep" and just keeps doing that.
i5 750 OC'd to 3.6GHz
4 GB G.skill 1600 RAM
550w OCZ fata1ity PSU
Should be noted that last week is the first that I've OC'd the i5. I had it at 3.2Ghz stable for several days before stepping it up to 3.4, at which point I had to increase the voltage a little bit to get it stable from testing in prime95. Then, the day before yesterday (May 21st) I bumped it up to 3.6Ghz, increasing the voltage a step or two again. It was running fine. Prime95 testing for several hours and the temps on all 4 cores never went above 65 degrees Celsius. Usually stayed around 60-61 C under full load.
