Fortnite causing monitor crashes and occasional PC crashes

[GhostieBoy]

I just built my first PC like 2 or 3 months ago. I7-10700k, MSI 3060ti, nocturnal cooler, 32GB of DDR4 RAM, and a couple other minor things that probably are kind of irrelevant to this issue.

 

I have been enjoying many games up until recently. Fortnite specifically has left my monitor crashing and occasionally my PC completely crashing. And now there's something buzzing?

 

I'm at a loss. Any advice? Any other info you need just lmk

 

Edit: more info on crashing-

 

My monitor just either shuts off or goes to black screen and says "connection not found" but everything besides the display works. I can no longer heard game sounds, but I can still hear the discord call and my PC lights are still on, but shortly after the call audio goes weird.

 

As for the PC, it just clicks off (audible click) and reboots itself. No bluescreen

What do you mean your monitor is crashing?

Are the computer crashes bluescreens or straight to power off?

Monitors wont crash. Its most likely your graphics card driver is crashing.

Sorry I guess I could have specified a bit better. I'll edit it with more info.

Okay, so those are two different symptoms of what is probably a single issue: Dying PSU
The first one is a crashed GPU driver (the old Windows + Ctrl + Shift + B shortcut might fix a crashed graphics driver, though it never has for me) which can happen for all sorts of reasons

The second one is bad power. Either *really* dirty wall power, or the PSU is dying, regardless, the system detects that the power is out of spec and shuts down. 
This conclusion is supported by that buzzing noise. 
Can you check HWInfo and see if your voltages are in range? Also start up furmark and make sure they *stay* in range.
