My computer starting rebooting randomly about a week ago and then today finally completely shut off and won't restart. I pulled the ram and still did not make it to the Bios. Code flashes AA 21 right off the bat. I have reseated all connections that I can find, that it would make any sense to have a problem with. The motherboard is Taichi X670E. The processor is Ryzen 9 7950X. Memory is Trident Z5 AMD EXPO 32GB. I run my whole business out of this computer, and I need it up and running as soon as possible, any suggestions are appreciated. |

You may want to pull the CPU and check the socket and CPU for issues. Continued uneven pressure can cause the CPU substrate to bend. Also, pull the CMOS battery and disconnect the system from power. Press and hold the power button for 5 seconds or so to discharge all the capacitors in the PSU and motherboard. Leave the system like this for 10 mins or so then put the battery back in and power up. -------------
