Hello, i hope i can have a clear answer on what i should do so i can enjoy gaming peacefully without worrying things might happen and ends up destroying my pc, so long story short my pc shuts down sometimes when i'm gaming, usually it happens when i play games like sniper elite 4 or R6 Siege for almost 3 or 4 hours straight then it goes back on itself like nothing happened, no warnings no anything, and i'm using an Automatic Voltage Regulator, sometimes it also happens the moment my regulator making quite loud buzzing noises (it happens randomly), i searched up about the problems and most people said it might be a faulty power supply or the regulator since it made unusual noise, i'm wondering if i should replace my power supply or stop using the regulator or is it better to do both?
P.S: it doesn't happen when i do normal usage such as browsing and stuff, and my power supply came with the casing so it doesn't have certification like 80+ or brand as good as corsair and stuff
Specs: Intel Core i7-2600, Colorful GTX 1050TI, 16GB RAM, 1TB HDD
