ATI Fire GL4 is AGP Pro 8x. (Fire GL, not FireGL, wildly different cards.) It's quite an odd, uncommon, rare card... 

Seems like you left out the part of this story where you describe the actual problem?

Used DDU?? If not, try using DDU.

No do not bother at all. The performance difference is almost nothing for a MASSIVE cost that is insane

RAID IS NOT BACKUP!!!!!
 
Now that that is out of the way. What will the setup be? You can have a raid array for the server and then back it up to another server with a raid array or the cloud.

pretty sure its actually slower... and if not its about equal. 
 
ie it makes *zero sense*
 
eh, *3080 minimum to be a worthwhile upgrade imo.

grats on new disk..
1 disconnect old drives. 
2 disconnect ALL old drives.  windows is funny.. and can put the bootloader on a different disk if it finds one. it usually don't but hey. why not be sure. 
3 download AHCI/Raid drivers for your mainboard unpack into a folder you copy to your install usb. 
when booting be carefull to use the UEFI image when loading windows. 
let windows create everything it wants. so since there is no partitions on it your good.. if it is.. delete them all.  there is no need to make 2 partitions.. . you can access it.. if you don't see the drive at first, select load driver and find the ahci drivers you downloaded earlier. 
4 windows likes to create all partitions when installing it on a drive. let it.. point it to the unformated disk and it should be GPT to see anything above 2TB. since that is MBR limit. old tech we don't need. 
 
partitioning up a system drive is old tech.. there is no need to do it.. not on win 7 either .. linux needs it. but your not installing it. 
 
as preinstall preperation you might check in bios that your nvme settings are ahci too. that uefi is turned on.. not cms 
read the manual to check if any of the sata ports are disabled when you use the nvme port you are using.. it usually is. 
 
 
 
 

Agree to the above, if Windows have been shut down unexpectedly enough times I think the issue will be with files not old registry keys. If SFC and DISM don't help a clean install WILL. Clean install and a winget script and maybe some custom batch/powershell scripts to bulk install applications. Will get you nice and started.

A registry cleaner will do nothing for you, unused registry entries make no difference to a system. Your issue could be caused by incorrect mounting of the CPU cooler, failing memory controller on the CPU, failing RAM slot, damaged traces between CPU and RAM, debris in the RAM slots, dirty and/ or insufficient contacts on the RAM modules, loose connection at either end of the display cable and the list goes on.
It is possible an improper shutdown has hosed the system in some way, but again a registry cleaner will not help you there.
Use SFC /scannow to check for Windows file corruption.
Check the disk for file system errors with checkdisk and for physical errors with HDSentinel or similar.
A repair install of the OS would probably help if the are no hardware issues found, this will re install Windows files and associated registry entries and settings while keeping your apps and files, there are several good sites with tutorials for how to do this, tenforums and elevenforums are good tutorial sources.
Remove McAfee.

Yeah, I mean. Corsair labels the 24-pin and if you have two thats cat 4 then you know they are the same. I wouldn't risk it without labels like that.

Being the same brand doesn't necessarilly mean they didn't change the cables.
I wonder too why you would need to remove the motherboard to replace cables. Anyhow, I believe this can be done with a multi meter. Find your grounds and stuff see if they are in the same place.

Same brand isn't enough, but on same series they would obviously use same pin layout, else it won't be a series...
But it's not a certainty I admit
 

Try run
Start-Process powershell -verb runas -Argumentlist '-File "G:\Backup installasjon\Scripts\apps.ps1"'  

Once you've planted that laptop, it probably no longer works again. Especially once you've watered it.

You need safe mode but you don't need to redo the whole thing, go to Advanced Startup in the recovery, then you can start in safe mode from there.

What Killah said.. I've done this a lot with 2012 servers that are running on HDs and schlocky RAID controllers like bargain basement Perc 300s and moved that mess to a single sata SSD. Even done it with RAID 5. The feeling of bliss when I'm not running off that pile of spinning rust waiting to let the magic smoke out is amazing. 
 
Macrium will do the move, but windows will want to boot into the prior RAID environment and this is causing your problem. Oddly Windows Server backup and restore does this trick. Most cloning tools have a problem because they are doing a true clone. 
 
Try setting windows to boot into safe mode, then do the clone. When windows boots on the new device it will be in safe mode it should resolve the issue. Same process as moving windows from RAID back to ahci.

In principle yes, in practice your cloned system will likely not boot until you start it in safe mode from the recovery partition/boot media, afterwards it should be fine.

I wouldn't. It would just reduce GPU budget, which you probably gonna need buying 4000 series. 😂

There is no way to know for sure. It all depends on how games are made in the coming years but I wouldn't risk it considering it's such an expensive card and I can promise you one thing. Games wont get smaller.

Or a fan hub (nicer solution imo, cost $10)

It's good right now but it has a budget card memory bus so I don't think it will stay good for long. Plus it's way too expensive. I wouldn't buy it.

HWInfo displays the values of sensors. I've had one motherboard which at some point spat out rediculous values. Fans going at 200.000 rpm and 14 million volts here and such crazy stuff. I think it got normal again after clearing cmos or something, I don't remember exactly. /shrug
 
Apart from that short period al my sensor values on several computers have been plausible in HWInfo as well as backed up by other monitoring software. If you are unsure of HWInfo values use Ryzen Master if you have Ryzen CPU.

Just reboot. Should be fixed by downloading new files from MS servers.
