My computer is messed up, I think, crashes and so on (noob friendly please)

[RetroZ_99]

so i got a new PC and after a few days of play games on it i stared experiencing games disconnecting no reason it just disconnects nothing popping up, also i want to add that my friend thought he could over clock my pc with msi afterburner which he just messed around (HE HAD NO IDEA WHAT HE WAS DOING) and saved it then he reset it and it went back to normal, a few days later i experienced what i said above and after the game crashed then around ~15min if i would run it again it would show the blue screen saying there was a problem and it had to reset, i have no idea what is wrong with my computer. examples of games i play are Counter Strike global offensive and H1Z1 both disconnected, also when the game disconnected steam did too.

So overall i experienced disconnects, random restarts and blue screen

please help this computer is new and very expensive i put lots of money into this and want to play on it again asap

What do you mean by disconnects? Your post is extremely hard to understand.

It's possible your memory can't handle the games you play. What're you're laptop's specs?

No idea why I assumed it was a laptop lol but anyways, you should start your posts with your specs. It's in the rules, just your ram doesn't cover it, also monitor your gpu and cpu usage and temperature.
