I have an ASRock Z77 Extreme4 mainboard using an i7 2600k CPU. The mainboard is a replacement for a previous Asus P8P67 Rev 3.1 that seemingly died about a month ago. One night my computer shut off and would not power back on at all with the 12v CPU power connector connected. Other users who owned this same board had reported similar failures, so I decided to replace the board. I ordered the ASRock, installed the CPU, heatsink and RAM and when I tried to power it on, the board seemingly got power (HSF spun, Dr. Debug LED lit up) but I did not get any post beeps whatsoever and had a 09 error code on the Debug LED. I researched the Debug code and it is listed as, "South Bridge initialization after microcode loading" in the manual, the ASRock website lists it as a possible memory problem. I uninstalled RAM completely, hoping to just get a post error and still no beeps whatsoever. I contacted ASRock support, reseated everything, performed CMOS clear and still no post. I finally RMA'd the board to Newegg, received a brand new replacement, installed mainboard, CPU, HSF and RAM and on the initial power-on I got the same error message on the LED yet again. Once more, the board gets power, HSF spins but no post beeps whatsoever. At this point I think it is my CPU which is very unfortunate because that SKU is still very expensive and I had OC'd it so I don't imagine the warrant will cover it. My OC was steady for two and a half years, multiple stress tests and gaming sessions and monitored temperatures in HWMonitor were always steady. Prior to ordering a replacement CPU, I wanted to ask the community for any further opinions. Has anybody else ever had that Dr. Debug error code before, or is it most likely an issue with the processor? Thank you for any help in advance.
