Boot Loop With Mostly New PC

I am currently in the process of building a PC. I already had a PC, and decided to reuse some parts. I am reusing my GPU, PSU, and HDD. I put everything together and booted it up to see a blank screen and my EZ debug CPU and DRAM lights on. After moving around ram sticks, the screen actually turns on and I can get into the BIOS. One thing I notice is right when I turn the PC on, the CPU EZ debug light comes on for a second, disappears and the screen turns on, then goes the press f11 for run boot menu and DEL to get into the BIOS. Then the aspect ratio changes, the cpu debug light comes on for a second, and the PC says restarting and it does so. This will keep looping until I either get into the BIOS or turn it off. My thought was that since I reused my HDD without it being a clean install and just did a sysprep, that it is for some reason not able to get to the windows screen at all. I had the retail version, and I will get the USB stick of the version I have tomorrow, since it is at another house. So am I correct to think that this is the HDD? Is the CPU the real problem? Should I reinstall the components back into my old pc and delete drivers? Should I reinstall the components and do a clean install instead. Your help is very appreciated.

New build specs:
Ryzen 1500x
MSI B350 PRO-VDH AM4
GeForce 750ti
Sata 1TB seagate hard drive
500W bronze PSU
2×4GB DDR4 Ballistic ram( Only using 1 atm)
Windows 10

Old Specs:
AMD Anthlon X4 760k
Generic FM2 MOBO
GeForce 750ti
Sata 1TB seagate hard drive
500W bronze PSU
DDR3 6GB
Windows 10

If you do not have critical data on the drive I would just pull everything apart. Pull the CMOS battery from the board and start with a fresh install as follows.

  • ■ Disconnect all drives except the one you are installing on
    ■ Restart with your boot media inserted (or boot from BIOS or advanced start-up menu)
    ■ When you are in the Windows install program, before selecting a drive to install on:
    ■ use Shift+F10 to open a command prompt

    ■ type the command "diskpart"
    ■ type "list disk"
    ■ look at the list to determine which is your drive (there should only be one)
    ■ type "select disk 0" or disc 1 or whatever it is
    ■ it should say something like "disc 0 is now the selected disc"

    ■ type "clean"
    ■ alternatively you can type "clean all" which is a more intensive wipe but takes longer
    ■ I have generally had good luck just using the "clean" command, sometimes several times in a row (seemed to help once)
    ■ If desired, you can format the drive here by typing "format MBR" or "format GPT" depending
    ■ type "exit"
    ■ you can now close the command prompt and continue with installation as normal, just select your disk, which should say "Unallocated Space" and begin

Just hold on for a moment before you start reinstalling components, OK?

1. It's really unclear (at least to me) as to your actions to date as they pertain to installing the Win 10 OS in your new system.

2. I take it you're using (or plan to use) your previous 1 TB as the boot drive (presumably MBR partitioned?) in the new Ryzen system. And that's the HDD that also contained the Win 10 OS in your previous system. Correct?

3. Now I'll assume that HDD is non-defective and performed perfectly well in your "old" Win 10 build, right?

4. Would I be correct in that you would be perfectly comfortable to reinstall the Win 10 OS onto your new Ryzen build with all your personal files, apps, etc. intact?

5. In other words what I'm driving at is that you aren't particularly interested in a "fresh install" of the Win 10 OS with the need to reinstall all your programs & other data, right? You're fine if you can simply (in effect) transfer the former boot drive to the new system as long as all your data is safely contained and perfectly usable. Is that the case?

6. If that is the case why not simply install the HDD with all your new components for the Ryzen build and use the Win 10 installation media (the DVD or the Windows Media Tool flash drive with the Win 10 setup files) and go ahead with the installation of the OS.

7. Obviously you'll probably need to install whatever drivers are necessary from the MSI driver installation CD/DVD (and you may be pleasantly surprised at Windows (Microsoft's) ability to detect the necessary drivers during the initial boot to the OS and install them without user intervention.)
 

Unless there are mitigating circumstances I would say that a clean Windows install is recommended with new hardware. There will always be less issues and weird problems to troubleshoot.
 
My bad for the late response. I haven't tried anything yet. I was fine with doing a clean install, because at this point I just want the system to be working well. I was trying to avoid having to use a boot media, but if I have to then I might as well do a clean install as well.
