I have an asrock b450m/ac R2.0 and I upgraded from a ryzen 5 3400g to a ryzen 7 5800x and it turned on and started working fine. After i ran a benchmark i was looking at the results and then the computer bluescreened and wouldnt turn on after that it would turn on but then just keep restarting. My computer works with my old processor. But i did update bios, i did everything i could but it still wont work anyone know?
 
Perhaps there is some sensitivity to the RAM. Does it use more than one RAM stick? If so, can you try each stick, one at a time, in just the first slot?

Also, if you have XMP on, try temporarily disabling it.
I have 32gb (2x16) of ripjaws v 3200 and i cant enable xmp for sum reason because when i try to enable it I get the same problem that im getting with the cpu the pc will turn on but it will just keep restarting

I would suggest testing under memtest86+. This runs on a thumb drive or DVD or whatever temporary boot media you have, and does not actually install anything. It simply runs in RAM, and its purpose is to test RAM (one would at minimum run for about 4 hours; one of my old jobs used a 48 hour memtest86+ burn in as a minimum).

More importantly, try with a single RAM stick, one at a time.

what is memtest?

XMP is for Intel processors. AMD chips use DCOP.

Memtest86+ is a tiny self-contained operating system running entirely in RAM. It sole purpose is to exercise the RAM with various patterns. Memtest86+, once loaded into RAM, does nothing with hard drive, networking, so on. When the system reboots, memtest86+ is gone. As it runs the system warms up, including the RAM. Every possible way to work with RAM for storing and recalling memory is tested over and over. This means that if the address of failure (if there is a failure) is constant, then that RAM stick is bad; if the address of any failure changes, then there is something "marginal". I would expect overclocked RAM to have more "marginal" cases than normally clocked RAM (that's just for the sake of example). If you run this with one RAM stick, and nothing fails, then with another, and nothing fails, then with both RAM sticks, and then something fails, I would expect it to be an issue of the sticks having slightly different timings.

Also, it is free, it definitely is not malicious, and you simply boot with it on a thumb drive or similar. When done, just reboot.

EDIT: I always run at least 4 hours. In a commercial burn-in environment I would run for 48 hours. If you run overnight this is a very good indicator of memory. It would also suggest the CPU is good.

Am i supposed to do it with the new cpu or the old cpu?

Both would be useful, but since the new CPU is what is failing, then this would be most useful with the new CPU. If memtest86+ works on the old CPU with this RAM, and has XMP disabled, then it should also work on the new CPU with XMP disabled. If there is a failure on the new CPU, and if it is a memory failure, then it might just be some qualitative issue with that CPU using that RAM. Just be sure to test a single RAM stick at a time, and if that works with at least 4 hours of testing, try both RAM sticks. If it is the RAM itself which is bad, then this should fail in a similar way on both CPUs (which is possible; the new CPU might be using memory differently, and the old CPU might fail at that same memory location, but if the old CPU simply does not run into that address very often, or with non-critical software, it would still be bad RAM).
