So i am using a Gigabyte GA-A320-2SH. I purchased this to run with a RYZEN 3 3200G, 16gb ddr 4 installed also. I install the M2 drive KING DIAN 240gb PCIE NVME M2 2280 Internal SSD High Performance Solid State Drive (NVPRO480 240gb). It runs amazing. I get everything installed and im actually very happy. The issue comes when i install a 1tb normal hd (Seagate Barracuda) for secondary purposes. At first everything runs ok. Things boot up fine and i see all my drives. Everything looks great. I shut the pc off for a few minutes and the M2 drive is no longer there and it is going back to bios which then i cant even see the M2 drive on the bios. If i unplug the seagate hd everything comes back and i can see my M2 drive again. I can then plug back in the seagate hd and things run fine until i shut off the pc and the same thing happens all over again. I here that my M2 drive may be utilizing a certain amount of sata slots. But this doesnt make sense to me why things work for a bit. Its just weird considering when the seagate hd isnt installed the M2 runs stellar. When i get home im going to try some different sata slots for the seagate HD. Do you think i just have a cheap M2 drive i should of not purchased in the first place? I cant find anything with my mobo having this issue. I know its a cheap mobo so maybe that's also an issue. Please help .
