Computer problems after installing ryzen 5 5500

[fearofthemrak]

spec:
Mobo: asrock b450 pro4(bios 5.6)
Cpu: ryzen 5 5500 ( i had 3400g but swap it for this one)
Gpu:1070 msi aero
Cpu cooler: arctic freezer 34
m.2: some generic Samsung 240 nothing fancy
storage: Kingston 240GB basic one I use it for dota and cs go to load faster
Wd: generic 500 GB hard disk that I store all games that are 100GB plus
Casefans: 3x NZHT P series
PSU: Coolermaster MWE White 600w
So let begin
I had ryzen 5 3400g that I swapped with ryzen 5 5500 that I bought from aliexpress for 83 euros plus shipping. It came without a cooler. It arrived I updated mobo bios to 5.6 (it was the latest at that time) boot into windows(dint reinstall it)
played some games everything worked perfectly. The cpu cooler that I use for it keeps my cpu cool at gaming (max temp under stress-test 65*)
The first problem I had when i played doom eternal, it just rebooted my pc, temps were fine, cpu was around 56* gpu was around 60*, so I decided maybe I put to much pressure on my tower cooler on cpu that it causes some problem. After that everything worked like a charm.
Like 10 days ago I started to see some unauthorized entry on my google account, steam account, discord, Facebook, instagram ect ect. Somehow someone managed to follow 500 people on my instagram profile. 
While that was happening I wasn't at my home so I could not react. I called my sister to go to my home and plug out the pc from the wall because I know someone gained access to it. After that couple day has past and my sister's kids wanted to play some Minecraft, they turned on the pc and launched Minecraft, and pc shut down rebooted with fans on max for a few sec and it go back to windows, they tried because they are a young couple of times and the same thing have happened. I instructed again my sister to plug the pc from a wall and that when I come home ill handle that.
When I came home and wanted to start my pc everything booted just fine, I disconnected pc from the internet and I did some basic antivirus scans. It found something and I deleted it.
I did some stress tests to see what will happen and it happens. My pc rebooted with full fan spinning posted, and back to windows. The second time it allowed me to do the stress-test cpu and it held it for 10 minutes without shutting down. I plugged in a USB with fresh windows installer and reinstalled my pc. Now I can't get to the windows and if I do get in windows it let me be there for a couple of minutes and that's all. It also froze in bios many where I wanted to check maybe its the temperatures but it was not.
What I did so far:
Reinstalled windows with fresh drivers
Reseated ram stick
Reseated cpu and cooler
Reseated gpu
Removed cmos battery
Checked on bios is C-States activated (it was deactivated)
Reseated all cables and double checked they were connected properly

And now while I am writing this from my laptop and want to boot on my pc it wont, fans are just spinning and that all no beeps from mobo speaker nothing

Sounds like a defective CPU

Installing a new CPU isn't going to cause for someone to gain access to your computer and do all that shit with your accounts. The most likely culprit for that is letting children use your computer. I see it almost everyday, people let their kids use their business or home computers for games and they download or do stuff they shouldn't, causing all sorts of issue with virus'/malware and security breaches.

 

From the issues you are having and with the troubleshooting and steps you have already taken the most likely culprit is your PSU, if possible I would try a different unit. It could also be the CPU itself. You'll need to do further testing to be sure of which one but it's most likely the PSU or CPU.

 

And stop letting children use your PC or at least don't have anything important on it if you do.

You got hacked and it has nothing to do with the CPU you bought - You just weren't careful enough.

Also blindly shooting in the air won't help you solve the other issue you are having.

 

What i recommend:

Try testing the CPU with Prime95 with the Small FFTs option for a hour.

Try testing the RAM with Memtest86 for 3 hours.

 

Tell us if you get any errors while testing.

Thank you for your answers so a little update on what I did

So I have an old pc that I know for a fact is working its a 

i5-3570

mobo:msiB75

I started with elimination. I wanted to eliminate PSU and GPU. So my old pc would not also boot with the PSU, same thing happens fan spins but it won't boot, so I took the old PSU from that PC its an old generic MS bad PSU that I got with that computer when I got it from my parents and I know for a FACT that PSU works. I plugged that PSU because of curiosity in my old system and then "WHOALA" the same thing happens. I dint use 1070 with that PSU I used an HD 7850 just to get a picture and it is the same, GPU fan spins at full blast, CPU fan is just spinning nothing more. No post no nothing. that is kinda strange. I am hoping that PSU dint short something inside my old pc and it friend everything, or here in my country our power delivery infrastructure kinda suck and atm there are some strong winds, so maybe just maybe it's electricity. I'll dig some more and update what I did next

About the hacks I get it cpu from aliexpress and the hacks are not connected

Thank you once more for answering I am hoping that we will figure this out for other poor souls like me who are in same position like me
