clear the CMOS and see what happends

what happends when u power it on ? fans spinning and for how long ?

try whit whit only one ram stick but one at a time .. could be ram issue

overcloked ?

Its a Go...!! whould reqomend 3000mhz+ memmory like a G.SKILL F4-3000C15D-32GVR

well for media its well enuf.. and it should handle those titels well

It whould be good to know what your planning to do whit the Laptop... could give u a bether answer

No

Dedicated sound card will always give bether sound quality.. (if u have the correct drivers for it) intigraded sound is good for most of every day activitys

you will know it the machine crashes or not you do 1 day of testing whit one stick.. if it crashes then it might be that one then test whit the outher if it crashes whit that one also then its probably not the sticks but if it crashes only on one of the sticks then that stick is probably the faulty one..

are u able to test a new mem stick ?

no you will not notice any diffrent exept if u run AAA titels at very high graphics

There is no reason to think that a pci-e adapter for m.2 and a gpu cant run at the same time on that mb https://www.realhardwarereviews.com/msi-970a-sli-krait/2/ im having abit hard to get the full picture on what the are saying in that text.. but a m.2 adapter for 3.0 x4 PCIe should work but ur gpu will only run at 8x insted of 16x

not sure but kinda sounds like one of the problem i hade a year ago... in my case it was a faulty memmory stick.. do a Windows Memory Diagnostic run and see what u can find out.. https://www.howtogeek.com/260813/how-to-test-your-computers-ram-for-problems/
