PC randomly restarts when gaming

[cooldoody11]

When i play games like minecraft or league of legends my PC restarts randomly with no warning.
Its starting to happen more and more often. I want to fix this problem because it is getting very annoying

Does the computer lose power or does Windows simply restart? If the former you're looking at a power supply issue likely (or motherboard). The latter could be overheating.

I don't think it is power supply it just simply restarts. My friend has the exact same pc and his works fine

Try running a boot time memory check, like memtest86+. I wouldn't be surprised if something turns up. Make sure it goes through one pass and randomly uses your CPU cores. You may have a bad stick that is only apparent when you memory is mostly used up.
