remove gpu device , and check it again , remove ram modules and check it again. if possible remove processor , and reinsertwith good applied thermal paste , if possible add good Processor fan.
in many cases , loose connection cables are fault , faulty ram modules , or faulty GPU device.
dont overclock , keep only default settings in bios. if possible read user manual of MB see triubleshooting steps in user manual.
in my own single sided ram module does not compatible with double sided ram module supported motherboards
