Does pressing F2 open your boot menu or your BIOS(It's different motherboard to motherboard)?

All it takes is for GTA to come out with a random update and it can tank performance

Around the 30's for temp is completely okay, even if that is in idle

How old is the PC? Like was it built recently If it's been a minute and you use the PC often, then you may need to change the thermal paste. If it's a brand new build than that likely isn't the problem as far as thermals go. How are you cooling the CPU? Air cooler? Liquid Cooler? Do i5's even come with stock coolers anymore?? With my old i9-10900k, I was experiencing randoms crashes just from having the turbo boost on within my bios by default. Once I turned off turbo boost, all of my random crashes completely disappeared.

When you press F2 and it starts a boot loop, does it go to black screen first and then starts the boot loop? Or does it immediately start the boot loop upon pressing F2?

Does your mobo have any flashing lights on it when you are trying to boot? If there is an LED somewhere and its flashing in a way you could detect a problem happening. Some motherboards will even have a small LCD panel to display codes whens booting problems occur

Silly question but is your GPU plugged in all the way? Both into your motherboard and PSU to your GPU if necessary?

You could try to install windows with a couple of the parts removed? Then install them afterwards to maybe explore the part(s) that may be causing a bad install. Your CPU should have integrated graphics, try removing the GPU and installing without it, then adding it after the full install(assuming the install works properly of course). There is also the case of you having two sticks of ram, make sure they are both in the correct slots. All motherboards generally have a specific place for them. Check your motherboard manual for the proper slots for your use case scenario and desired performance effect. After all that, if none of that works, you could also try underclocking your CPU in your BIOS just so that it doesn't use the turbo mode. Turbo mode, factory or not, can sometimes cause a few issues here and there thanks to the good ol' silicon lottery.

You could try removing your gpu driver and reinstalling it to see if it was just a bad driver install/update

Starting to sound likely faulty ram or a faulty motherboard.

A scratched screen is a scratched screen man. It likely won't mess with the longevity of the screen, the same way if you scratch a phone screen it doesn't just randomly die from it.(Assuming the scratch or crack isn't exposing any internal hardware.)

I feel like 9/10, if someone is having an issue with a GPU, it's almost always poor luck and a broken GPU.

I'd recommend trying both just to see if it works and if the performance is better one way or the other. Really the only thing hindering anything is time. Especially since you already own both sets of RAM. Worst case it performs worse, best case you have a little more RAM to do as you please.

I was having a ton of blue screen issues when I was using my i9-10900k. I ended up having to go into the bios and disabling the turbo boost feature for the cpu. It sucked losing a small amount of performance but all the issues stopped thereafter. But it couldn't hurt to make sure your rig is completely updated both within your windows OS(I assuming you are using windows) and as well as your GPU drivers being updated. Edit: What are your full system specs?

You can try updating your OS with any available updates as well as making sure whatever gpu you have installed is also up to date. Secondly, you could also try scan and repairing the game itself. Is this is a reoccurring or was this just a single odd occasion? If it's only happened the one time, I would almost just say that it is likely just a random software or hardware glitch and a pc restart would probably fix it.

If your PC managed to boot with the GPU disconnected, it very well could be that your GPU was causing the problem. Although you could try reconnecting the GPU to your PC just to rule out it not being connected all the way, being moved around can maybe create enough momentum for it to wiggle out of place slightly. When you describe boot, do you mean like booting into your OS or just no longer being in the boot loop?

Unless something drastic has happened to your PSU, I'd guess that your PSU isn't the culprit

You could try booting it by shorting the boot pins on your motherboard(just to rule out a couple of problems that may be causing a failure to boot). If this works, it could just be that either your PC case io isn't connected properly or needs to be fixed/replaced(this would probably be the easiest fix). Do you have fast boot enabled in your bios(Does your bios screen usually pop up before booting into windows?)? How old is your PSU? Rating? Model? You could also try booting your PC without your GPU installed to rule out a bad GPU. Since your CPU has integrated graphics, you should be able just to plug into your motherboard for a display.

You could try resetting your bios settings by removing the cmos battery, if any changes you made are preventing it from booting properly, they should return to the default settings

Sometimes within your bios, there are settings you can change to alter whether or not certain ports still provide power after a shut off

What type of storage are you using right now? A hard drive? SSD?

Have you tried unplugging the other monitor(the monitor that is working) and trying to boot(or even while your pc is on honestly) with just the monitor that is supposedly not working?

Are you connecting the monitors to a graphics card or just a display port(hdmi, etc.)?

There may be a setting to allocate your bandwidth to nicehash(within nicehash), but otherwise nicehash might just be designed to eat up internet
