can only game for around 10 mins before system locks up

hey, so ive been having a funny problem with the system for a few days now, its crashing any time i have a game open for longer than 10 or so minutes.

I've made no changes to the system that im aware of. it used to work flawlessly.

The crash when it occurs causes audio to cut out on my headphones, both monitors freeze on whatever image was on them at the time, and no input is registered, ive left it around 5 mins before rebooting each time but nothing seems to happen.

So far ive tested 3 different games, Elden Ring, Street Fighter 6 and Guilty Gear Strive, all with different versions of proton including the valve version and the latest GE version.

I'm checking journal but doesnt appear to be any obvious cause prior to the crashes, but the timing is pretty consistent across each of them.

last time i suspected maybe some overheating so i had open a system monitor page i made with the temp sensors graphed on it and the highest was my cpu around 50-60 degrees, which is fine.

Any advice would be greatly welcomed, i really dont want to have to deal with this nonsense rn
