My PC crashes during boot up.

Hey everyone. First post. Yay.

 

Going to try be as succinct as I can be here. So, starting on Wednesday my PC crashes seemingly out of nowhere. I was using it at the time (playing Horizon Zero Dawn, but I doubt that's relevant), the display loses signal and the fans all ramp up. So I restart the system, it's booting normally until it reaches the log in screen when the same thing happens again; blank screen and ramped fans. This happens every time.

 

Here is everything I have tried so far:

• Disconnecting all cables, from the motherboard and the PSU.
• Reseating all hardware, including the CPU.
• Tested with a single stick of RAM; tried each stick separately and in different slots.
• Reinstalled Windows. (This took several tries, and even at the point when I had disconnected all drives but my boot drive AND formatted that drive, it did the same thing during the reinstall process several times. Which makes me think it isn't a software issue but a hardware issue).
• Updated BIOS to most recent version (Version F61c, it's an Aorus board, full specs at the bottom)
• Reset CMOS.

I will note when it crashes the CPU and RAM status lights blink back and forth. Now I'm under the impression that a solid light indicates a problem with those components, which has me leaning towards a problem with the motherboard. But I'm completely unsure and that's why I'm looking for advice. Unfortunately I have no other hardware to test with, nor does anyone else in my household have a desktop. Also I must mention that this isn't a new system, I put it together in January 2019 and have had very few problems since then.

 

So that's where I am, I would appreciate any advice I can get.

 

Specs:

CPU: AMD Ryzen 2600X

MB: Aorus B450 Pro

SSD: WD Black 500GB M.2 NVME

PSU: Corsair RM650x

OS: Windows 10 Pro

Hard to tell,you would need to test each component individually and see what would happen.

Stress test GPU,CPU,RAM PSU and look what would happen.

Random reboots usually are RAM issues and PSU.

Yes I agree, being able to swap out hardware would be the easiest way to determine the problem. I just don't have any other parts to test with. Which is rather frustrating. I also hardly know anyone who still uses a desktop, everyone is on laptops these days.

Ok then do with software:

Memory test-->Memtest86
PSU test-->OCCT

CPU test-->Prime95

GPU test-->MSI Kombustor/Unigine Heaven
