Just started today. Was able to let it automatic repair and boot up. Was on for like 10 hours, shut down and tried to boot up some hours later. Now its completely stuck on automatic repair. Have unplugged all additional hdd's and then all unnesscarry USB's. Still doing this. Also removed my ethernet card. Still the same.
I cannot lose my data. I have several SSD's and HDD's with important files across several of them.
Do you have a separate GPU installed and does your CPU/motherboard have a built-in GPU? If so may as well try unplugging the GPU, plugging your monitor into the motherboard video port, and see if the system boots up. (this is just in case it's actually some GPU issue)
Otherwise, maybe a long shot - How old is your computer? You mentioned Windows 10 which makes me think it's possibly on the old side.. if something like 8-10+ years old it could be that the battery on the motherboard needs to be replaced and your entire system is acting up during reboots (this is especially obvious if there's any power outages). Try doing a BIOS reset - if there's a button on the motherboard to do that you should be able to press it, otherwise just take the motherboard battery out, unplug from power for something like 30 seconds, then plug power/battery back in and try a boot up. That could get you to at least boot up past the BIOS and you may want to consider buying a new battery to install into the motherboard. ... I don't know if Windows 10 itself would start after all this but at least you can find out if the hardware is still okay.
I dont think mine has integrated graphics. Its a rog hero crosshair viiii.
5 years old this June. Built it myself. No issues i couldn't solve or handle on my own until now.
We DID have the power shut off a week or so ago... my PC may have been on during that time. I honestly dont remember.
Could that be the culprit? Why was it fine for almost a whole week?
