Hey everyone, I have a PC I built myself and have had it for almost a year. For the past week or two, I've been getting random restarts, about 10-15 minutes into games. It's been getting worse, it restarted while I was simply watching a video today!

My PC specs:

Intel Core i5 4690k 3.5 GHz
MSI H81M-P33 (MS-7817)
NVIDIA GeForce GTX 1060 3GB
8GB RAM
1TB HD
480 Logisys PSU

I have a very similar issue to this thread: (http://www.tomshardware.com/forum/56480-2-computer-restarts-randomly-playing-games-help), with similar temperatures, so I know it is not an overheating issue. Suggestions??

I looked under administrative events in the event viewer, and saw several "Critical" messages in the midst of all the errors and warnings, all labelled "Kernel-Power". According to the descriptions, this only happens when the system crashes, stops responding, or loses power, which does sound like the case. What can I do if my PSU is the problem? It came with my case. Thanks in advance.
