[SOLVED] PC became extremely slow overnight

[Sulerium]

System Specs:
CPU: i7-4790K
GPU: 5700XT
RAM: DDR3 16GB
HDD: 7200 RPM WD Black (one 1TB and one 2TB)
SSD: 500gb Samsung
OS: Windows 10 (most recent update)
Monitor: 1080p 144hz

I already posted about this before but it's a reoccurring issue and I'd like some help...

My computer was working normally and was playing RDR2, Modern Warfare, and Resident Evil with no problems at all. But after one night, my computer has begun being extremely unresponsive and although I've gotten it to be more responsive after some time and restarts, trying to open games like Modern Warfare and the new Resident Evil is impossible for this thing now. Sometimes running applications such as Windows Settings, Control Panel, Task Manager, Google Chrome, Wallpaper Background, and Razer Synapse is too much for this thing.

From what I can tell, my cpu isn't overheating and all my fans are working normally, I've tried cleaning my hard drives with applications but I'm unsure if that has helped, and I'm looking for a free malware scanner to see if that's how it's happened.

It all occurred after a Windows Update, which I was prompted into connecting my windows account to my gmail and phone and a bunch of other ****. I attribute this to the cause because after logging in and discovering my pc was being extremely slow yet still having a high frame rate led me to believe it was my CPU getting overloaded. Well I realized my 4 core cpu was being limited to a single core. But even after I've unlicked the CPU, my PC hardly works. I'm unsure if this update has changed certain presets I've changed on my computer because they slowed down my PC back in the day and they are all building up. But I haven't got a clue.

Other suspicious things that have changed is the fact I used a website called "GamersGate" which provides game keys for cheaper than retail and they did something called "manual overview" for one of my purchases. I'm unsure of the reason for the manual overview or what that entails.

Someone has already recommended it was these keys causing the issues and I had acquired a virus, well I've completely wiped all of my drives and downloaded a fresh install of Windows 10 and it's still not working properly (even after making sure I turn on my processors cores).

I'd like to get my PC up and running again so I can play these new games and do things with friends because of Corona-cation. There's not much to do and I'd really appreciate some help!

I'm not sure what was going on, what occurred when, what all was downloaded, or, what the above sentence means or might have been intended to mean, but, ...

you are likely going to have to flatten this installation, i.e, ...start over!. Nuke and pave....quick format/reinstall.

Back up any actual user files, photos, etc., that are important to an external USB drive and/or cloud storage account.

Have someone with a functioning system use the Microsoft Media Creation Tool to make you a Win10 installation USB flash drive (8 GB minimum) Gather your mainboard's available Win10 chipset drivers from manufacturer's website.... YOu can get the AMD drivers for the GPU online as well, then download/apply all WIndows updates, which might take a few attempts at updates, depending on your connection speed.

You can reinstall just one game that you were troubleshooting to see if that helped. (Avoid whatever bogus games key sources /services you were using.)

Hi,
Did you run an antivirus scan?

stupid idea. disconet the 2 HDD and see if still slow. cause im guessing the ssd is your boot drive.

I've already done that and completely wiped all storage devices and I'm still seeing issues.

Actually it's the HDD cause I got the SSD first, but when I say slow I mean games run ridiculously choppy and sometimes just outright quit.

I did run an antivirus scan and Windows said there was nothing wrong. When I checked task manager though, I saw that it was windows programs using up my CPU.

disconect other drives except boot drive and see if choppy.

(most use ssd as boot, hence the confusion)

Trust me, whenever I reinstalled everything I tried to put it on the SSD but it just did that automatically, I think I have a spare Windows 10 Pro out of the ordeal so it's not bad. Whenever I come across the issue again I'll try that and let you know how it turns out; sometimes the issue fixes after restarting the PC but it's quite rare.

I would do a memtest and an /sfc scannow in an admin command prompt just to rule out some potential long shot issues. The fact that you reinstalled windows and the problem still persists suggests to me that the problem is not software related. I would also look to update your Motherboard BIOS in the off chance that something malicious is lurking in the firmware.
