PC reboots when playing games

[iosifkh]

Okay so the first time this problem occurred to me was when I first started playing PUBG.It just randomly restarts, nothing else.. no dead bytes nothing.After that it started happening on multiple games such as DOTA SWTOR Age of Empires III.Now I don't know if this is GPU OR PSU or anything else..

PC SPECS
PSU: Corsair NEW VS Series VS550
GPU: GIGABYTE GTX 960 OC 4gb
Motherboard: GIGABYTE GA-H81M-S2V
CPU: Intel i-core i5-4460 3.2mhz

Check the system temps. Could be bad contact between the heatsink and the CPU.
