|For a recent birthday I got a new Dell XPS desktop. It is a beautiful machine with fast 64GB DDR5 memory and two M.2 connectors for NMVe drives on the main board. I did not like the somewhat slow NVMe that Dell installed as a systems drive, so I replaced it with a fast Samsung 980 PRO NVMe.
I was doing quite well with a clean install when I got to trying to install a very old cd/dvd application for dvd burning. It had 2 separate plugins for Dell machines that you had to run separately. This app was from the days of Windows 2000 or XP and I should have known beter than to fool with such an old piece of software.
When I tried to run the second plugin, it suddenly reported that there were no drives attached to the machine. Next thing the operating system died and the machine refused to restart. I could get into the BIOS but that was all. Nothing I did in the BIOS did any good. There were no visible drives in the machine (I had previously installed 2 NVMe drives and 2 regular Sata SSDs). It also had no visible USB3 ports so I could not boot from a repair flash drive.
Later it occurred to me that the USB2 ports were still working, so I did have a functional keyboard and a mouse to work the BIOS with
After a couple of hours struggling, and starting to panic big time, in desperation, I decided to uninstall all 4 drives one at a time. But I did not hold out much hope that this will achieve any result. But when I removed the systems drive, the machine suddenly came to life! What a relief!
Hours later, having re-done a clean install on a different drive, I started to figure out what happened. Using Diskpart I inspected the defective systems drive and it reported the drive was "off line". Running the Diskpart command "online disk" on the drive, immediately brought it back to life!
That plugin that killed the machine must have knocked the systems drive off line. When the systems drive went off line, it must have blocked the entire PCI bus to which it was connected. Hence no drives or USB3 ports worked. That will teach me to mess with very old software in a brand new machine! That old software worked like a charm on machines that it was intended for.
My machine is now back and running beautifully on the Samsung 980 PRO!
Get me coffee and no one gets hurt!
