I am trying to install Debian on a new prebuilt, but when I

figures it out, but by that time it's too late to tell the
BIOS to boot from a USB stick on which I've installed netinst.
The mobo is a Gigabyte B450M DS3H WIFI (rev 1.5), manual at
<https://www.gigabyte.com/Motherboard/B450M-DS3H-WIFI-rev-15#kf>.
I can see some letters on the garbled screen, but have not
yet been able to figure out how to get to the boot order.
So, either of 2 things might help me:
(1) The complete key sequence at the BIOS screen (or its <F1>
help screen) to tell the mobo to boot from the USB stick first.
(2) Some way to boot that stick or its
contents directly from inside Windows.
These symptoms are most certainly indicate a hardware problem and
probably a BIOS problem. Nothing to do with OS boot process.
I've read through some of the answers and there are options to try:
1. Try another HDMI cable and another monitor/TV.
2. If your PC has two RAM sticks, try to boot PC with just one. Try to
switch them with one another and try other memory slots. Also try
another DDR4 RAM stick if possible.
3. If two options above didn't get you a normal POST screen, try to
update BIOS from Windows.
If these these options won't resolve this problem, and you won't get a
normal POST screen, I suggest to return this PC ASAP.
There is nothing other you can do to fix it, and if you keep it, this
problem could progress further, or show itself as other issues, like
infrequent BSODs and Kernel Panics, etc.
It has a hardware problem, a faulty CPU(iGPU), faulty motherboard (HDMI
connector, CPU socket connectivity, RAM slot connectivity, etc) or
memory stick compatibility issue with current BIOS.
What's your AMD CPU model btw?
