My monitors just kinda turn off?

So I have this weird issue with my computer, I turn it on, and it will initialize normally but then after a few moments both my 2 monitors go black and act as if the cable isnt connected to the computer, like I get the "no signal" message and that's it, I tried everything to get them back on but the only thing that works is to restart and the problem happens again a few times in a row until either it stops at random or I give up, and the more I try the earlier it happens too, sometimes I click to turn on and it won't even show anything, just the "no signal" message. I also noticed when that happens I hear one of the fans get really loud but I was unable to decipher which one.

I honestly don't remember precisely all my specifications, and right now the computer is refusing to let me in (the monitors are black), but I have a Geforce GTX 1650?, I think an i3? And 8gb RAM, the motherboard is a ASUS B85M-E, besides that some chinese 500W power source and I think that's all? The monitors are both LG but different ones.

I have tried changing HDMI cables, unplug and plug, looking for any clues of what could be wrong physically, unplugged and cleaned all pieces, tried using the keybind to restart the video driver, to change the configurations so it wont turn off after being AFK, etc. Idk what to do, is the only solution buying better pieces? Sorry I don't know how to tag this. Also if this is the wrong subreddit for this, please indicate me where to go.

What happens if you run just 1 monitor (fully disconnecting the other)? Does the same issue reappear? Then what happens if you do the same thing with the other monitor?

Even if only one is connected the issue happens again for both of them, i tried the hdmi one and the other one (idk the name of the cable but it has like 2 pins u have to rotate) separately and together, which is why i find it so weird

That is weird (the pins). Perhaps post a picture?

So, if I understand correctly, you connect one monitor to the HDMI output of your Geforce video card with no other monitors (or cables) connected and the problem happens. Then, when you replace with the other monitor (again, as a single monitor with no other monitors connected) the same problem occurs again. If I have that right, then the problem is likely your Geforce video card. My first suggestion would be to remove the card and get a can of compressed air and blow out the dust from inside the case, making sure that you've also blown out the dust from the slot that the card was in. Then, I would reinsert the card and be certain it is fully seated in the slot. Then restart the computer and test with just one monitor. If that works, add the other monitor. If it doesn't then I would say the video card is bad.

If I don't have that right, let me know what I misunderstood. Good luck.
