Hello I Recently purchased a m.2 to upgrade my storage. This would be WD_BLACK SN850X 4TB a little bit pricey but I taught I’d enjoy the faster read and write times. The Main problem I have been experiencing is this m.2 not being recognised in BIOS (meaning windows will not notice) I will say to this there have been times it will boot and I will see the M.2 in bios but they are few and far between to narrow down why. the one time it has been recognised I have formatted this.

Here are my specs:

CPU : AMD Ryzen 5 3600

MOBO : B450 Tomahawk max

GPU : Gigabyte 2070 super

Ram : 16gb corsair dominator platinum

Storage : Samsung 870 Evo( Boot drive ) & 2tb Seagate HDD ( disconnected)

PSU : Corsair RM750 750W Power Supply 80 Plus Gold

(built 3 years ago)

I will say the reason I have purchased a m.2 was because my old HDD was having some problems with noise and the Sata cable.

Now I like to think that I could at least do a few searches before I make a post. So here is what I have tried up until now

1 Re seating M.2

2 Cmos clear

3 Starting the PC Without the 870 ( worked once to recognise m.2 but since has not)

4 Changing from CSM to UEFI

I have tried a lot to trouble shoot this within bios as well so I might have tried something you could recommend.

now with how old my PC is and the chipset/CPU being a bit behind after everything I have tried the only thing I could think to do would be to try a new MOBO/CPU. But even if I do get this I would like to think that I have tried everything first.

Please let me know what you think :) I am grateful for the help
