Question I need help diagnosing an issue, I think it a graphics card problem

[MackyPGR]

This is a tough one to explain, so please feel free to ask any questions you need to help me figure out what’s wrong. Thanks in advance for your help!

My PC runs fine, but for some reason, it randomly "turns off." I cleaned it thoroughly, as I suspected it was overheating, and for the last couple of days, it was running fine. But today, it turned off again, so I need to figure out the issue so I can fix it. I hope you guys can help me.

I was playing a game on Discord with a friend when the PC "turned off" again. However, I was still able to talk to him—he could hear me, and I could hear him—so it seems like the PC isn’t actually shutting down. Instead, the monitor is turning off and won’t come back on.

I think it must be graphics card-related. If I reset the PC, it loads back fine and works normally. The issue just happens at random times.

Does anyone have any idea what this could be or what I can do to troubleshoot and find the actual issue? I’m stuck for ideas.

Welcome to the forums, newcomer!

If your system shuts off without any warning, when under load, it's probably due to one of two reasons;
1| your system is suffering from an overheating problem
or
2| your PSU is incapable of delivering power to the entire system when taxed.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

No doubt, if Discord is still working your system is still on. If you unplug the monitor from the computer and replug does it turn back on? Are you using HDMI, display port or another?

Thanks for the in depth reply mate. I have no idea on much of this info though lol. The PC was built for me. I could guess... but it wouldn't be close. Where can I find this info and I will get it. Thanks for your help too!

I have a 4k monitor, so its not HDMI, but similar to it, just for the 4k... damn, i feel like a right noob, sorry I cant be of more help when explaining what tech i have lads.

I unplug the monitor, and plug it back in, but that doesn't get it working again. only restarting the PC gets it up and running again

We need to know if the computer locked up or is limping, or died... Does the keyboard still work when it "shuts down"?

What happens if you hit CTRL + ALT + DEL ?
