Hi, I have bought ASRock X670E PG Lightning + AMD RYZEN 9 7900X @ 4.7GHz + Patriot Viper Venom 64GB (2x32GB) 6400MHz some 4 months ago. It works nicely, but time to time (and it seem to be more frequent recenty) it fails to boot. It displays something that looks like a non-blinking text console cursor in the top left corner of the screen and has "BOOT" and "VGA" diagnostic LEDs solid red. Sometimes it recovers on its own after long minutes, sometimes it just stays like this for hours (until manual reset). I was suspecting memory training. But, as I stated fiddling with the components and sever times triggered real memory training it turned this issue is not memory related. I have tried the following: - Disconnecting all non essential components - Switching RAM slots, trying both modules separately - Alternative PSU - External and internal graphics - Update BIOS to 3.08 - Clear CMOS and try with fresh I wonder if I am missing something or it is the time to stop playing with the conundrum and RMA the components. All the best, Mattty |

Hi, finally I found out where the problem is. After re-seating all the high profile stuff like RAM, CPU, NVMEs I realized I have a USB 3.1 card reader connected that is buggy and fails to enumerate. This happens rarely in both Linux and Windows, but seems to be frequent in BIOS. Seems like the boot code has no timeout on waiting for a USB peripheral to enumerate. After replacing the card reader that does not take eternity to enumerate the problem seems gone. Hope this helps someone, Mattty |

Hi! I'm glad that your problem is solved now. However, because your RAM speed is so high, compared to the supported spec of your CPU, I'd download MemTest86, put it on a FAT32 formatted USB flash drive, boot with it and run it until the test finishes! If you'll get errors in MemTest86, you'll have to lower the DRAM speed of your RAM kit in the BIOS, or select a profile with lower performance (if you have such a profile). I hope this helps... |

If anyone finds this thread because of searching for a static cursor or underscore and red VGA LED: I solved this by disabling fast boot and "Above 4G Decoding" for an old GTX 1080 that does not support Resizable BAR. |

I think it was the Fast Boot the issue, and not the "Above 4G Decoding", because I've had that enabled for a long time, while my GPU was a GTX 1050 Ti, and I've had no issues. |
