I'm having a major issue trying to install Windows. Every time I start the installation process or even stay on the installation screen, my computer just bootloops. I've already spent quite some time troubleshooting, and here's what I've found out:
- Ubuntu runs perfectly fine, I've had it installed and working for four days.
- All drives seem to be functioning properly.
- Memtest showed no issues at all.
- The CPU is working fine.
- My graphics cards are also fine; I've tried several.
- I've reset and updated the BIOS, and that seems fine.
- Tried installing with three different memory sticks in every slot.
- Used multiple USB drives for the installation.
- Went through the official Microsoft installation process, and also tried using Ventoy and Rufus.
- Reseated the CPU multiple times as well.
- Reset the CMOS several times which didn't help.
- I also attempted the installation without any USB devices plugged in.
- Played around with various BIOS settings by enabling and disabling them.
- Used different hard drives for the installation too.
- Switched HDMI cords, which I know might not make a difference.
- Reformatted the drives numerous times.
On top of all that, my PC went into sleep mode one night and hasn't turned back on since. Any help would be greatly appreciated!

Since your PC went into sleep mode and didn't wake up, that might be linked to the issue you're experiencing now. If you've ruled out all hardware suspects, it could be your motherboard or power supply that's causing the problems.
Have you checked if your Windows installation is being done on a SATA drive, M.2, or SSD? It's crucial to ensure your BIOS is set up correctly for either CMS or UEFI settings before starting the install.
I've tried both a SATA drive and an SSD, but no luck.

Do you think Linux uses different power or hardware management that could affect it?
