[SOLVED] PC started stuttering during games and sometimes crashing (blue screen)

[Bazzlebrush88]

Hi everyone, my PC started stuttering during games and sometimes crashing (blue screen) with an error message either saying system store exemption or unexpected store error.
It's never had this before now. Any ideas?
Also games will randomly sometimes (only some games) just close randomly at a certain point in a game.

Am I right thinking this is faulty RAM?

Cheers in advance.

Specs:
Acer predator G-605 motherboard
Intel i7 4790k
Nvidea Gtx 1070ti
8gb ddr3 ram
Windows 10
500gm SSD
2tb HDD

have you reinstalled windows? I would clear everything on a software level before replacing parts
