My pc is in a boot loop and I dont know what to do. Upgraded from a 1600x to 3600x 3 weeks ago My specs are 3600x X370 Taichi G.skill flare x 3200 16gb Samsung evo 500gb Running the latest bios for the Taichi 6.20. PC has been running fine until now. Suddenly it is caught in a boot loop and I cannot get into the bios (no post) Dr debug throws these codes out in this order 33 7A 3b and finally b6 before the system loops. I have cleared my cmos, tried single ram in every slot, re mounted my cpu. No change in behaviour same boot loop same codes. I have no spare mobo or ram on hand to test. |

Try the 1600x CPU if you still have it, that will rule out a bad CPU at least. As process nodes have shrunk the frequency of dead CPUs has gone up. -------------

| I literally sold the 1600x a day before this issue happened. My bad luck. |

Had the same issue using a 3700X on this board and BIOS 6.40. Happened after I reset the CMOS. Removing RAM sticks, CLEAR CMOS and holding power button down with power supply did not resolve. After install a 1600X and downgrading the BIOS to 5.80 the computer booted just fine with the 3700X. There is an issue with the later BIOS revisions (6.xx) on this board if using some of the ZEN 2 CPUs which does not show up immediately (usually CMOS reset is the trigger). As previous poster stated - try a ZEN 1 CPU to resolve the issue (beg, borrow or steal). If you dont have access to an earlier CPU then try steps here: https://tinyurl.com/22x4mk9n" rel="nofollow - https://tinyurl.com/22x4mk9n |
