Question Working computer no longer boots up

[HonestBob]

Okay this is my current machine:
AMD Ryzen 5 5600X 3.7 GHz 6-Core Processor
MSI PRO B550M-VC WIFI Micro ATX AM4 Motherboard (BIOS 7C95vHD1 (09/05/2024))
Corsair Vengeance RGB Pro 32 GB (2 x 16 GB) DDR4-3600 CL18
Western Digital Caviar Blue 1 TB 3.5" 7200 RPM Internal Hard Drive
PNY CS900 500 GB 2.5" Solid State Drive
Western Digital Black SN770 1 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
XFX Speedster SWFT 210 Core Radeon RX 6650 XT 8 GB Video Card
NZXT H6 Flow ATX Mid Tower Case
EVGA 600 W1 600 W 80+ Certified ATX Power Supply
Win11

It's been running without a hitch for two years. Yesterday I upgraded a drive in my kids' computer and was replacing a Intel 660p 512 GB M.2-2280 PCIe 3.0 X4 NVME. I had an extra M.2 slot so I thought I would use it. Once I put that in, my machine would no longer boot. I have deleted the partition and formatted it. The PNY drive that I was using for a boot drive has been deleted and formatted once I backed up all personal files. I tried reinstalling Win11 on both drives and once it installs, just stops during an update in the process. I have never seen a machine behave the way it is.

When I hit the power button, it's like the machine doesn't know what drive to boot from even though the bios is fully updated and is set to boot from the PNY drive. I need help yall.

Disconnect all drives except for the one you wish to install the OS on and see if you make progress. Did you recreate the bootable USB installer?

the bios is fully updated
For the sake of relevance, what BIOS version are you on for your motherboard?

I upgraded to 7C95vHD1 (09/05/2024) after this started to see if it would help. All drives are disconnected except for the target disk and I did use the media creator tool to make a bootable USB for installation. I know the power supply is on the lower end but it's the only leftover bit from my previous upgrade and is the next thing to be replaced.

I misread about RE-creating the installation USB. I'm doing that now on a different USB key.

I tried reinstalling using the other USB key and right towards the end, the screen just went black and everything stopped. Tried rebooting it and it just sits there...

PSU is pretty bad.

Could be unstable ram remove the cmos battery. And reinsert it after a minute has passed. Set ram speed to 3200.

From my personal experience MSI boards have ram conflicts alot.

IME, use no overclocks of any kind while doing BIOS and clean installs. Reset CMOS and go. Make sure the system loads, is stable, THEN consider XMP/EXPO/OC.

edit to say- Unaware if you live in a location where static electricity is common but is there some chance you discharged to the motherboard while making the changes?

I would go through the machine and check all connections very closely. Reseat the RAM/graphics solution, and so on. It might be worth breadboarding the system with minimal hardware.

Before doing that I would at least test that PSU with one of the cheapo Amazon testers. If it says the thing is bad you for sure know, for $10. Not to say that if it says it is good that is for sure.
