The computer is halted on the motherboard and displaying a loading screen.
Your machine is frozen on the loading screen displaying your motherboard details. It worked normally until you powered it down. After a couple of hours, you restarted it and it became unresponsive again. You've checked RAM, GPU, and even swapped CMOS batteries twice. The first time you chose Ubuntu, it crashed into a black screen for about fifteen minutes before shutting down. The second attempt only brought it back to the loading screen without any boot options. CPU is Intel i5 10400f, motherboard Gigabyte B560M DS3H, GPU GTX 1050 ti, RAM Corsair Vengeance 2x8GB, power supply adata 450 BR, storage includes an ADATA 240GB SSD and a 240GB Kingston SSD. Please let me know what you see now.
When boot options and loading bars disappear, it means no system is being detected. Verify your SSD is connected and powered on. Access BIOS and choose boot priority to "Windows Boot Manager" if available. If Windows isn't installed or not visible, select the drive holding Ubuntu/Windows—likely the SSD—and try again.
The SSD is powered and connected. Upon opening it, a loading screen appears along with some initial prompts that vanish shortly. All control buttons—F12, DEL, and END—remain inactive, though the keyboard stays active and connected (such as enabling the number lock indicator).
I would reset the CMOS. If your board lacks a specific Clear Cmos button, you should find two pins at the bottom of the motherboard labeled something like clrtc or cmos. Connect a conductive material to those pins for about 10 seconds, then power on the PC. If this doesn’t resolve the issue, try shorting the pins while the PC is frozen on the splash screen—this should have helped previously. If it still doesn’t work, please inform us and we’ll proceed further.
I attempted this, but shorting the pins while powered off didn’t help. Shorting them during the splash screen caused it to turn off and then back on, only to get stuck again. The motherboard’s Q-flash plus button also didn’t seem to make a difference. Apologies for the ongoing problem.
Use spam f12 and del immediately upon turning on the PC. You may need to try a few times, but it should open the BIOS for verification. Please let me know if you manage to access the BIOS.
The Windows boot menu is displayed when the window manager is chosen first. Check if you can see the loading screen. It may indicate a damaged boot sector or entire drive issue.
