Hello,
I just bought my new PC components and built my PC, its not my first time building it and everything is connected properly.
The problem I'm having is that the PC is just restarting all the time, I somehow managed to download windows but that doesnt matter because every time I get to my desktop on windows the PC restarts, there is nothing I can do because every time I try to do something my pc restarts before I even manage to get close to that.
Oh yea, and also it freezes every 5-10 seconds and than works again, sometimes it restarts after 5 seconds, sometimes less, sometimes little more. In my head the only problem that can cause this is the PSU that i got from a friend that is not new, because everything else is new and I dont see a possibility for a problem.
Now... should I buy a new PSU or?

My specs are:
Cpu: Ryzen 5 3600
Gpu: GTX 1660 Ti OC
Motherboard: AsRock AB350 PRO4
SSD: Maxtor Z1 240Gb
HDD: Some toshiba 2TB
and an used PSU: MAXPRO 700W

My canned random reboot Rant
Random reboots are usually caused by the PSU, the RAM or software AND in that order of likely-hood.
PSU - If you can borrow/swap a PSU for testing. sibling/friend you can swap out the PSU and each system will be testing the other.
RAM - run the system with one stick of RAM see if stability returns if not Test all the RAM with memtest 86 for five passes or overnight. if you get no 0 errors after more than five passes the ram is good. with the random reboots I would suggest running this test after the PSU swap or after the PSU has been cleared.
Software - Drivers or other issues can cause reboots. Boot to a linux distro on a USB drive. mint linux will boot to memtest86. you can run the OS from the USB and await reboot.

Found the problem, my ram is too powerful, its 2x 8GB 3200 MHz, lowered it to 2666MHz for now, probably getting a new motherboard
