You'll have to look in Disk management to see if that's it.
Hello evrbody,
I have assembled a new pc recently, my config is as follows:
mobo: gigabyte z-170x gaming 7
CPU: intel i7-7700k @4.2GHZ (no OC)
RAM: 32 GB (16+16) G.Skill 2666 GHZ
GPU: GB Radeon Rx480
HDD Seagate 1 TB
HDD WD 2 TB
SSD Kingston 256 GB
4 standard fans
Watercooler Corsair H-100i v2
Firstly I had settled a power source of 650W Corsair, but once I tried to boot the computer, I saw that one of the HDD was not recognized in BIOS. So I switched SATA slots some times, until I realized that the problem wasn't the HDD.
I was still unaware about the problem cause, but as I saw that after 3 USB's connected at the same time, one of them simply wasn't detected anymore, I was convinced that I had a problem with power supply. So I exchanged my previous Corsair 650W for a EVGO850W, what didn't help at all.
The problem still persists so I ask for this forum help if my intuition was right, and how I can manage to resolve this? In case I have any other hardware problem, how can I diagnose it?
It wasn't bothering me so far but I am afraid if I don't get over this issue, it won't be possible to connect some extra USB's which I will need very soon.
Appreciate any help, thanks in advance.
