I built this PC in spring of 2013 and for the majority of that time it has served me well. Now I am one of those people who tends to leave the thing running for days and days without rebooting. So one day last September I noticed it was off and I went to turn it back on and nothing displayed on the screen. So I opened it up and the dr debug code is flashing back and forth between 10 and 15. Without using the slow motion feature on my phone camera, it would have been harder to see when the code was 10. So I messed with a few things including removing/swapping RAM sticks around, trying a couple other power supplies off the shelf at Best Buy, and even tried a new bios chip from ebay. At some point I tried moving my graphics card and wifi card to different slots, and it seemed like that was around the time I got past those codes again. Additionally, after all this, it seemed that my HDMI on the motherboard had stopped working as well. Now it's showing these two dr debug codes again, and I have tried everything I can think of, including everything I mentioned above, and even unplugging everything (SATA, USB, fans, RAM, etc.) from the board except the CPU (and fan) and power. Looking for any suggestions.

Try the following: https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal" rel="nofollow - https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal Instead of putting the batter back in however, leave it out and try to turn on without it. If it's bad it could be corrupting values in the UEFI. If the system revives and gives you POST, replace the battery with a new one. They are readily available from many sources, it's just a CR 2032, common in many devices. I can even find them in my local supermarkets. If it still won't POST reply here and we can see about other troubleshooting steps. -------------

Pre-EFI Initialization (PEI) - memory initialization code ranges: 0x10 up to 0x2F PEI execution up to and including memory detection 0x10 PEI Core is started 0x15 Pre-memory North Bridge initialization is started northbridge is inside CPU northbridge also contains memory controller so either CPU or RAM related try to check if there arent burnt marks on your CPU contact pads ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

I do not see any burn marks on the contact pads. They all look nice and shiny. |

| I ran into this problem yesterday with the same motherboard, dust had built up in the RAM slots causing the board to cycle between error codes 10 and 15. I removed the RAM, dusted off the sticks themselves and thoroughly dusted out the RAM slots. I reinserted the RAM after dusting out the whole computer and it started up fine. Dust can cause a lot of problems, specially with ram. I hope this helps you out. |
