What red debug light exactly?
 
And what does it mean exactly?

The system is actually turning off?
 
Or is it just rebooting?

Not really sure, all the fans go down to idle, if I leave it for a couple mins it eventually restarts back into windows but if I press the power button it immediately turns off (ie unlike when you have windows running and you have to long press for immediate shutdown).

it's possible that 750w isn't enough, I know that's what is recommended, but for the 30 series, those cards seem to sometimes have huge spikes in power usage for very brief times, and for that reason need more wattage that might have been needed before, even more so for a higher power unit like a ftw3, and if you want to overclock.
 
it could be that are some points in the game where the crashes happen, you have the power draw spike, and it's causing problems. I can't say for sure that's the problem, but just meeting the recommended wattage, while normally quite doable, may not be the best idea for the 30 series.
 
does the same thing happen with a stress test or benchmark, or if you raise the power target a bit with an OC program?
 
another thing to try is older drivers, the last two releases have some problems, so I'd try older ones first, then look at power problems, if the computer isn't shutting down totally when the problem happens.

OK, so it's not shutting down then.
 
How is the GPU connected to the PSU?
 
 

3x 6+2 connectors direct from the PSU, all separate no daisy chaining.

Sounds more like a software issue to me.
 
Are all the drivers for the MB updated?
 
Did you use DDU to remove the GPU drivers before installing the drivers for the 3080?
 
Also what happens if you close PX1, does the system still crash?

Every driver on the system is up to date according to windows update, though the board bios is a version out of date (not really keen on flashing it if I'm having stability issues, though don't see why this would cause such a dramatic issue in terms of system stability?). Didn't use DDU for the GPU drivers, have had the same OS for a good few years so could just do a complete reset but again really not keen if avoidable. Not sure what PX1 is, assume you meant the EVGA overclocking tool? If so I don't even have it installed, I've used afterburner just to check temps but never tweaked anything.

 
Yeah, flash the MB BIOS and see if the issues go away.
 
Use a flash drive to do it, not in windows so you won't have any issues.

Weirdly I can now trigger it every time I select Reyna in character screen on Valorant, system crashes as soon as it loads the model. Issue also happening in other games but seemed more random, this is the only time I've been able to get it down to one single action. Agree it seems to be software related as that doesn't suggest anything to do with hardware that I can think of, presume a clean install is probably my best bet as opposed to hours of digging through drivers etc?
 

 
You don't actually have to do that.
 
You can do here:
 

 
Do an upgrade, it will save all of your files etc.

Unfortunately issue returned today seemingly at random. System keeps black screening and rebooting during games even after removing all graphics drivers via DDU. Will be formatting drives (nothing important on them anyway) and reinstalling windows from scratch to see if it removes the issue, otherwise assume it simply must be hardware (either the GPU or the PSU given that they are the only new components).

Get a spare PSU and connect your GPU to it separately and see how that goes, some power supplies new or old can't handle the 30 series it has nothing to do with the wattage or age.
