I really wish I had more to go on, but feels basically impossible to diagnose. Tried underclocking graphics card to see if it'd help but it didn't. Probably not cooling related, since temps don't get super high during load.
Computer specs are:
i7 7700 (not K)
RTX 3070 (used)
Asus Z270-P motherboard
3x 3.5 inch harddrives
1x 2.5 inch SSD
1x M.2 SSD
Corsair 650W PSU
#Screens stop receiving input when computer is heavily under load

What the RAM specs here?
polar eagle
uh 650 watts for a 3070? try getting like 800 or 900 watts cus it mite be trying to draw more watts than the computer has
wheat spear

That is enough speed and capacity.
So, how the CPU temp?
Under heavy load.
If overheat, performance will slow down a lot, depend on the temp.
wheat spear
peaks at 80 deg C, so shouldn't be throttling
the computer is well cooled and in a cold room, so i really don't think that overheating is the issue
polar eagle
peaks at 80 deg C, so shouldn't be throttling
so is your gpu overclocked
wheat spear
so is your gpu overclocked
underclocked atm, running it in silent mode on GPU TWEAK

yeah its the psu

Screen stop receiving input under heavy load huh..
wheat spear
so is your gpu overclocked
but it doesn't really feel reasonable? like the graphics card is the only thing drawing a large amount of power
vale rose
For PSU, 650w is really good at handling average task.

3070 lol my 3060 blew up my 500 watt power suply
wheat spear
the processors TDP is only 65 W, and I really doubt the graphics card is pulling 600
vale rose
Since settings on optimal, the GPU will optimize power efficiently.
Any issues, just input not working smoothly only?
wheat spear
Some graphical artifacts on some websites, but that’s it
vale rose
This used GPU, it a mining card or just heavy gaming GPU?
I think there are two guessing for me.
Is your O.S on SSD?
Windows O.S on HDD sometimes cause Input problem, because of the SysMain utilize, causing System delay and lagging, and Input not function or working smoothly sometimes, of course.
polar eagle
Some graphical artifacts on some websites, but that’s it
have you tryed rolling back your gpu drivers
oh yeah forgot to ask when it stops receiving input does the computer make any beeps
wheat spear
Is your O.S on SSD?
OS is on SSD, card is ex-mining
vale rose
Former mining card, not a big surprise for graphical artifacts appear.
One more question, your input hardware like mouse and keyboard, does them controlled by software, like Razer Deathadder and Razer Blackwidow need Razer Synapse control in order for stable input and function working properly.

Does not need it, but I have the software. Steelseries Apex Pro and Logitech G pro X

Alright, is good to know that.
For Graphical Artifact, can't fix because of GPU hardware.
As for input problems.
You need to utilize CPU load, if going high loads, you have fair chance causing disruption input lag or disconnect to it.
Since input always handle by CPU.
So, as for experimental solution, you need to close background applications that you are not using often or heavy demand it, because i7-7700 have limited cores to sustain application and software, especially under heavy load.
Make sure CPU don't go high enough like 80 to 100% utilization, once it reached the number, system will lag and input have fair chance disrupt or disconnect, especially wireless device.
wheat spear

I might have worded the issue badly, but the issue isn’t really with input lag. The screens are wired in with HDMI and DP, and they stop getting input when the computer is under especially high load. Not sure if input devices still work when it happens, since I can’t see if they do.
vale rose
So, it a video problems, huh.
Okay, let's ignore the top comments here.
Your RTX 3070 is an ex-mining card, so as you mentioned, there are graphical artifacts, might be drivers issues, or the GPU itself can't handle such heavy load because the component is wearing off because the GPU used to operate heavy mining.
I do own mining cards and know their conditions, I am not sure your GPU condition, but if the graphics load too much for GPU handle and the temp rise to 65 degree over (Or the heatsink aluminium has rusted - This cause GPU system fail even you maintain good temp), it will fail like the issue you have, input straight stop received.

Visually the heatsink looks alright, but ofc aluminum corrosion is hard to see
Temps don’t seem to be the issue, as it happens almost instantly and the case is well ventilated
vale rose
The temps fine, as you speak.
wheat spear
I bought a new 1000w PSU (to accommodate future upgrades), I’ll try to see if it fixes the problem like the person above suggested
vale rose
Sure, troubleshoot testing make perfect.
wheat spear
Not sure how to see if drivers are the issue, I am running the latest NVIDIA ones and the graphics card BIOS version is a manufacturer one, not a special mining one afaik
vale rose
Seems you already confirmed it, I will said either PSU not stable and powerspike it or Heatsink not working properly.
wheat spear

Is there any way I can check for the heatsink not working?
vale rose
They work, just the Rusty part make it worst perform.
Usually, you can see through the fan.
Or you can unscrew 4 screw backplate to open it up.
No need unplug the fan wire from the PCB.
Lift it up and you can see through.
Be advised, you will change thermal paste if you do that.
wheat spear
I’ll skip that för now then and hope the new power supply fixes it.
vale rose
No worries.
