I've also had phantom positives before, experienced an issue with a work PC where Windows defender kept saying it took action on something in notifications but there was never anything there in the logs and scans returned nothing. Eventually it quit happening after a few months and some updates.

So far things seem fine.

Full scan, for sure. Both times.

Sometimes Windows flags things as malware that are not. I had to add an exclusion for a program that tests for fake flash drives because Windows didn't like how it was accessing hardware, it's possible a software he used in testing may have that issue with a false detection?

There are a lot of possible reasons why he said what he said,but that doesn't excuse the lack of transparency. 
I guess so,The drive is not there so now there is no way for Windows Defender to remove files from there 😄
Do a full scan just to be safe.

It says 3600 now. Thanks, guys!

If you replaced your CPU, your board might be using default settings but still shows xmp as set. 
Disable xmp, save changes and reboot
enable xmp, save changes and reboot
see if it helps

It's possible that you lost the silicon lottery and the memory controller is not good.
 
The memory controller on the CPU affects the stability of the RAM,
So if you replaced the CPU,now you have a different memory controller.
This is the most common cause for RAM instability,It's not the RAM itself.
 
It will probably work fine with the older CPU.

You have to load the XMP to have the memory set 1.3500V and then you can play with the freqencies, but shouldn't XMP set the frequency?

not the best psu but not the worst either. Effiency like 80+ platinum is just marketing adn doesn ot affect the quality of the psu in anyway.

@WhateverchanI've never used UPS in my life and I had few Computers. I only had one problem when it comes to plugging power adapter to the outlet and it was when lightning struck near my house. Luckily, only power adapter was dead (it came on fire) 😄
After that, I've never experienced any problem. 
 
You can use wall outlet. 
 
As for your problem, I'd test power outlet first, and if PC restarts again, I'd take it to another room and plug it in wall outlet there just to be sure what's the problem.
Btw, are there any errors in Event viewer?

I really doubt it's the power strip unless it has visible damage. However, you ain't gonna kill your pc by it begin connected to wall power. It jut protects against power surges.

AMD has laid out the procedures on their website. You need the proof of purchase (they say they want original, but I sent them a picture I scanned with Office Lens app), and a picture of the CPU in the socket with the RMA number visible next to the CPU. The P/N and S/N need to be visible on the CPU in the picture for them to approve the RMA. Make sure you clean the CPU with some paper towel / soft cloth and Isopropyl. If you only ever applied regular thermal paste, you're probably fine.

I have recently gone through the RMA process with AMD and I can tell you that yes they are sticklers when it comes to there being any marks on the IHS. But  as long as the S/N and P/N are visible you shouldn't have to worry. You might, like I did, have to resend in photos as their agents seem to be incompetent or unable to zoom in on a high res picture sent to them. I had to end up zooming the image myself and resending it.

Other than that, I was pleasantly surprised they shipped me back a full retail 3900x within days of receiving the CPU I shipped them.
 
EDIT: I did have to pay to ship the defective CPU to them however. But you might be able to get them to cover that if you call up and complain.

@Biohazard777Lol. I meant, I could think of nothing that could have caused a spot like that. There was no food or drink near the spot. I mean, you could tell how high it was, right? XD
 
@tikkerYep. Tried cleaning both sides. Felt nothing. I thought of using windex or soap, but I was afraid it could have made the glass look worse. I think it's actually acrylic... It's not gonna get worse, is it?

Amazons policy is fortunately awesome
 
 
RMA, get an Nvidia  

So I’ll chime in on this one. 
 
Asus strix rtx 2060 not a single issue
 
Strix rtx2070 not a single issue
 
Bought a xfx dd ultra rx5700, nothing but issues. Tried every driver imaginable, every setting changed, I  spent probably 20 hours messing with it. Returned to amazon
 
 Bought a sapphire pulse rx5700xt. If I have amd enhanced sync or Radeon anti lag on it crashes. I didn’t change any other settings, turned just those 2 off and the card has been great. 
 
In my experience nvidia is easier if you don’t want to tinker with settings. I will be buying nvidia only from now on. 
Nvidia being loud is funny. Any card can be loud if the fan speed is thru the roof. I haven’t had an issue with either company being hot or loud. 

I've had zero issues with my 5700xt since purchase just after launch. No crashes, no issues at all. Unlike my 2070 which I had to rma 3 times in 4 weeks. Now I'm not saying amd is better than Nvidia. I'm just stating what I have had happen. 
 
And why don't you have the box?  I usually keep the box during the duration of return window at minimum. 

The noise level of the graphics card really depends on what fans/heatsink the card manufacturer slaps on there, the default fan profile set on the card, and if they screw up and use 10mm of thermal pads between the heatsink and the card. Different generations of cards will be different as well... So the notion that "Nvidia GPUs are loud[er than AMD cards]" is basically meaningless.
 
Before buying a card (either AMD or Nvidia) try to find professional reviews of the card that test noise levels and performance.

Agreed with @Slottr, most probably it happens with the OEM keys.
 
One more possibility can be there, if you have ever used pirated Win 10 on that PC, then the activation process tells you that "Could not activate your license due to could not connect to the MS server"

Make sure 'Windows Update' and "Software Distribution" services are in the running state. Hence, make sure Windows is getting updates properly.

We cannot discuss keygens as that constitutes piracy. As for cheap keys off eBay, most of them violate the terms of the Microsoft EULA as they're usually not retail keys from authorized resellers. Your best bet will be to purchase a key from the Windows store, from a local box store / retailer, or from Amazon.

^This^
 
It's probably and OEM key that was purchased by the company who sold you the laptop and can only be used by the company (If I'm not off-track) and not by an user on another computer 

Probably an OEM key so you won't be able to transfer it

Thanks! I'm not sure if the company will be that generous, lol. I want to tape the GPU cables because I'm gonna put some decorations inside the case, so I want less cables sticking out as possible.  Just plug the power cable in?
Yes, they are. I swear they don't have virus or anything, lol. I use links so it's easier and faster for the page to load.
