I was playing some Path of Exile when I noticed some glitchy things happening on my screens (use two monitors, both would flicker at the same time, hard to describe what I saw but it was like the images on screen would go on and off in a flash, with clear horizontal lines of this flickering going on. These events would last about 0.4 seconds and then everything would return to normal, until it would happen again about 30-60 seconds later. Not perfectly described, but I hope someone somehow understands that...)

I didn't know what to make of it so I fiddled around with some of the other stuff I had running (browser tabs, steam open) and it seemed like it stopped. About an hour or so later, while just chatting with someone on steam (PoE still running) I just got an abrupt Black Screen, computer was still running, but I couldn't hear anything, ctrl alt del, alt tab, and all that stuff wasn't doing anything, so I let it sit for about 5 minutes before I decided to turn off the computer without a proper shut down.

When I went to reload it, I would see the initial loading screen logo and whatnot, but eventually my main monitor would just say, "no signal" and they would both just sit there black screened, and I just let it sit there for several minutes. I turned it off and tried again, and it happened again. The second time after I powered it on again, I just let it sit there on the black screen for a while, and then the computer actually just powered off itself after a few minutes...

Any advice on how I should proceed?

Here is a much older thread with seperate issues, that might answer some questions you have about specs:

Other than that, my prior issues stopped (temporarily perhaps) once I stopped using sleep mode, and when the heat wave from summer ended.

tbh sounds like your gpu might be on its way out or your having driver issues.

As per the advice of a friend, they said I should try to remove the GPU and then boot the computer, see if it boots up or not (although I have no monitor when I do that.)
I think it didn't boot up, because my peripherals usually light up eventually through the standard process of starting the computer, and in this case, they don't. I also didn't hear any meaningful booting sounds.

Could that rule out the GPU? Is this potentially a Mobo thing? I'm not qualified to make any of those assumptions, but I'm curious what you guys think...

Edit:

I did follow up test, I removed the RAM from my mobo because my friend said that if I try to boot without RAM, the Mobo should always make a Beeping sound.
So with the GPU removed, and the RAM removed, and everything else plugged in, it didn't seem to be booting and there was NO beeping from the Mobo.

Does this mean Mobo is dead?

From the other topic... your motherboard is far too hot.

You need to either replace the thermal compound on the motherboard IC chips or get a new motherboard.

tbh i didn't read last thread earlier but apparently I stated my piece there back when it was posted.
The pc will only beep if it has a speaker connected to the mobo or an onboard mobo.
but your mate is correct it should give a bios beep code without ram in it.
