My computer became unstable since a week. First, I changed power supply. After that, I removed offboard video card, but no effect. So yestarday, it couldn't recognize my hard drive anymore.
I did a backup into another disk (Seagate - /dev/sda) and attached to my computer, where I started up a live usb Ubuntu 19.04. Same problems, same issues.
I changed SATA cables but no effect.
Would my motherboard is faulty? How to determine it? Look at /var/log/syslog:

Look that my system tries to connect at 1.5 Gbps and 3.0 Gbps, UDMA/100 and UDMA/66 alternately.
Weird! I have another disk (SAMSUNG - /dev/sdb) stable at all. Look at lshw -C disk:

Any ideas?
Problem solved... Just my fault. I buy a newer power supply, and it's not bivolt. As the voltage from my house is 125v and it comes 220v factory settled, I forgot to switch it to 125v, causing lower voltage!...
