[SOLVED] Computer goes black screen and fans speed up

[Sykii]

Hi, I've got a problem with a computer. I've been having random (and not random, I'll explain it later) black screens and I have to manually restart the PC when it happens It happens on two occasions:

First: While gaming It randomly does it, It's not after long sessions, I can play 6 hours without it happening and It can happen on the first game of the day, doesn't matter if It's a game with high graphics or lower.
Second: If I give a small hit accidentally to the computer It usually happens, for example If the pc it's on and I hit it with the mouse arm unintentionally.

An extended description of the problem: The screen goes black and the GPU fans increase their RPM I can still hear my mates on discord and they can still hear me for a couple of seconds, then I have to manually power off the computer and turn it back on.

I've tried the following:

• I've checked temperatures while gaming and idle, nothing strange everything seemed normal, also I mainly play league of legends, which is not a game that requires high specs
• Thought it could be my graphics card (RTX 2070) malfunctioning so instead of having two displays plugged decided to just having one while gaming, it happens anyway
• Reinstalled drivers
• Cleaned internally the computer of dust
• Unplugged and replugged the 6-pin conector of my card to ensure it was connected properly, didn't fix the issue.

Anyone has any idea of what could be causing it? After days researching I've just found that it may be caused either by PSU or motherboard malfunctioning, with the quarantine and all this stuff going right now, I can't afford buying a brand new PSU plus a new motherboard and still having the same issue, so I need to be sure about what's causing the problem, I don't have another suitable PSU or another graphics card to test, that's an issue aswell.

Computer specs:

• Processor i5 4460
• RTX 2070
• PSU 700W

Thanks in advance.
Kind regards

AMD Black Screen Driver crashes is a very common problem right now. Even something that I am dealing with. Interestingly, you have an NVIDIA GPU and it is occurring. Since you said that nudging your PC causes a crash, try reseating your RAM or graphics card and see if that fixes it.

I'll give that a try, thanks for your time

I agree, what you describe is a questionable connection somewhere that can be momentarily disconnected by a physical bump. It is likely that this is not a component failure that would need replacement, but that it possible.

Just to explain what you report. When your system first boots up on any re-start, the systems to control the speeds of your fans normally starts them all up at full speed to be sure they start. A few seconds later when the boot process gets around to reading actual temperatures with sensors, the automatic fan speed controls reduce those speeds to whatever is appropriate for the temperatures it reads. So the fan actions you are just system re-starts after the power interruption. What I find odd is that you say you can hear some audio from your system as this re-start is happening.
