PC Specs
CPU: Ryzen 5 5600X
GPU: XFX QICK 319 RX 6700 XT
Mobo: ASRock B450M Steel Legend
RAM: Corsair Vengeance Pro 2 x 8GB 3200Mhz
PSU: MSI Mag A750GL Gold 80 Plus
UPS: CyberPower UT1500EG

My problem is my PC kept on restarting even on idle or under load. My screen just turns black then reboots, sometimes it shows the Asrock logo, sometimes it's just the windows audio cue but no display. I need to restart it to have display again after the boot.

Also, sometimes when I boot there's no display as well. I'm not sure what the problem is, there's a WHEA 18 error on my Event Viewer, but kn the reliability it points to my GPU. I got my CPU tested and they said it was fine, tried stress test on my CPU and GPU and they were fine as well. It's just the restarts are too random, not sure what's triggering it to happen.

I'm kinda frsuted because I just saved up money to buy this and can't even use it properly. I forgot to mention that sometimes it's working fine for HOURS with no crash. It's just hapenning randomly.

Any idea what the problem is?

In line with what @Dark Lord of Tech suggested, have you tested your PC without connecting to the UPS (or at least not using the battery backed up outlets on the UPS)? If so, does it make any difference?

I forgot to add, I tried using the Safe Mode and it doesn't get random reboots. On normal mode, I get multiple errors in event viewer. WHEA 18, Kernel 41. But in Safe Mode there are no crashes or reboots happening.

Have you tried resetting the CMOS? If it boots to Windows with no errors try running it with default settings. Please post the results if you try this. If it is stable you can then tweak your PC for optimal performance once again. If issues appear again please post them as there are people here who can help with further diagnostics and help you get your PC running well again. Thanks and All the Best.

Hi, yes, but restarts are still happening.

When you assembled this system, did you perform a full, clean installation of Windows? Or, did you recycle an installation from a previous configuration?

Have you tested your memory with a tool like memtest?

I tried both, I used the previous and after that performed a full clean installation.
Also, tried the memtest on my RAMs.

I'm just curious why is it when I'm in safemode, my PC doesn't reboot or crash. Only in normal. Sometimes it's working fine, like right now, I've been using it for 2hrs already and no crash.

The safe mode thing suggests a driver issue. However, it can also indicate an actual hardware issue as well (like when a driver enabled all the features of a device).

When you installed the motherboard chipset and video drivers, from where did you get them? Directly from AMD?

Yes, I downloaded the chipset and gpu drivers from amd.com.

What make/model CPU cooler are you using? Also, do you have access to another GPU to test with?

Have you considered booting the system with a Live Linux distro to see how it performs with a different OS?

I'm using ID Cooling Aura Flow X 240

CPU and GPU temps are normal upon checking on idle and while gaming.

I haven't thought about using other OS, I've been using windows ever since and have no idea how other OS works. :)

You don't actually install the OS, you just run from a USB drive. Nothing is written to your SSD/HDD.

It is a good way to isolate a hardware issue.

I recommend Mint: https://linuxmint.com/

You'll be familiar with interface from the beginning.

Download ISO. Use an app like Rufus to write to a USB drive. Boot from the USB drive. That is pretty much it.

AMD support is quite good.

Alright! I will try it tommorow, because here on our country it's already 12am in the morning. Thank you for the advice! I will get back to you if I see any improvements.
