A pretty timely plot, given the current spotlight on artificial intelligence. SHODAN has gone rogue, threatening to fire a devastating weapon at Earth, and it’s up to you to reach the evil AI and shut it down. Waking up six months later, after an induced coma, you find you’re the only living being left on Citadel Station.

In a scene-setting intro, the character you play – an unnamed hacker living in a dystopian future city called New Atlanta – is arrested, transported to a space station called the Citadel Station and ordered to hack into SHODAN, the AI that controls the station, and remove its ethical protocols. Again, it doesn’t feel as thrillingly fresh and innovative as that of the original game, but there’s a very good reason for that: every single element of its gameplay has been copied by several other games over the last three decades. Gameplay-wise, though, System Shock is beyond criticism.

you also may have damaged memory, graphics card or cpu.There are other issues you soon encounter, such as the vaguely comical way in which the mutants you frequently have to dispatch lurch and stumble about, as well as their distinctly rudimentary character design.

drivers check them, do clean/complete removel of nvidia drivers, and install ONLY drivers without nvidia marketing expernience and tracking.Not saying you have exactly same problem but hdd or usb device connecting and disconnecting may cause crashes. So with occasionally disconnecting for a second it made laptop switch used graphics chip, and that made most games go derpy derp. i had DELL laptop that has intel and amd graphics, and bad quality connector for hdmi (quite popular in dell products).get on some PSU required power website and calculate if your psu is enough (multiple ssds / hdds do use power, so add them all).

is your PSU new? Its good quality so probably psu is fine.

had it time to collect dust for eg on CPU fan and radiator?

install some app that monitors temperatures of CPU and gpu, watch it while playing.

Limit FPS, there is hope it is just 3070 overheating.
