Crashes PC at idle or under low loads

Good afternoon (evening)! There is a problem as the PC crashes at idle (different time intervals). Can be when watching movies. The PC is new, about 2 and a half months. Bought in DNS. Took back under warranty, I attributed to the graphics card. Changed, the problem is not gone. Started looking around on the forums, was advised to try updating the Bios, test the memory and hard drive, to demolish and put back all the drivers. Have done all the treatments, nothing helped. Lucky again in service center CSN. After 4 days of tests at them such problems were not found. They began to think of food, or to be more precise on the network filter (for me it was already old). Replaced mains filter. As such, the problem went away (I thought). 2 weeks later started again missions. BlueScreen crashes and says error 3, and 2 of them often, 3-I very rarely. KMODE_EXCEPTION_NOT_HANDLED, IRQL_NOT_LESS_OR_EQUAL Is two major mistakes. DRIVER POWER STATE FAILURE — This error came out pretty recently. Recently I began to think on the PSU. Please tell me what to do with this problem ...
