[SOLVED] Trying to figure out if CPU causing internet connectivity issues

Ok, so bare with me on this.
I've got a Ryzen 2400g now that was in a HP desktop i bought, it's ran perfect for about two years. I had been running folding at home for roughly 3 months nonstop, one day, I put the pc to sleep, next day, I wake it up and suddenly it begins dropping wifi. I can restart the pc it works for about 60 seconds, then acts like it has no internet connection, still shows WiFi is connected, just no internet. Now i tried using a usb wifi adapter to see if it was my pcie card that went bad, same issue persisted. I tried a few more things, ended up completely reinstalling windows, nothing, same issue. So, I've now since replaced the entire motherboard, swapped the cpu, ram and hard drives over to a new case and did a fresh install of windows. Same issue is still persisting. I'm very positive it is not my router as I have 20 other wifi devices that have no issues at all but I do plan to connect via a Ethernet cable today to test that. So, not here's my question after all that, can this issue, somehow be caused by something in the cpu itself going bad? I'm just trying to get some confirmation on my theory before i drop money on a new cpu.

Ok, so I solved the problem. It turns out, that I actually had two bad wifi adapters, which both happened to be exhibiting the same symptoms, infuriating. I was able to get a Ethernet cable long enough to plug in and determine that worked fine, then borrowed another wifi adapter from someone to just give another go, and bam it worked. Nothing like having two separate components fail individually at the same time.
 
run userbenchmark.com and post the http link of your result, e.g. https://www.userbenchmark.com/UserRun/28977730

Reset the BIOS by jumper clrCMOS or JBAT or similar (eventually you will have to set the bios priority correctly after that)

check windows integrity
open the command prompt as administrator and type DISM /Online /Cleanup-Image /RestoreHealth

clean boot

check the memory by running memtest.org usb autoinstaller (bootable USB flash drive)

run the RAM @2133MHz to check if it happens then too

check the hard drive for errors with its manufacturer´s tool

Ok, so I can rule out the motherboard, this problem has been persisted between a complete rebuild with a new motherboard.
It's not Windows, I just did a fresh complete install, and the issue was exactly the same on old PC before doing all of this.
I will give the memtest a try and see about checking the SSD's.

I'll check that, but I'm thinking that's not the issue either and I'll explain why. It was working perfectly for months, then from one night to the next morning suddenly the issue appears, and has now persisted though rebuilding with a new motherboard and fresh windows install.
