Roho  Wow! your answer about the Realtek audio drivers seems to have been the culprit and the solution. I never used the realtek Audio on the MOBO since I had the PC. I always used the Sound Blaster card and sound drivers. I decided to uninstall the Realtek drivers even though I never used it. I had the realtek drivers dissabled from loading. What a difference it makes booting up. The Realtek drivers must have reloaded and enabled during a windows update. Thank you! Thank You1 Problem solved. I never would have suspected those drivers were the culprit.
I replaced 256G SSD card with a WD black SN750 Nvme 500GB ssd that was cloned from original 256G that was on XPS 8930. Now the PC boots extremely slow. I tried switching from RAID to AHCI but would not boot. This has probably been asked before but I can't seem to find the solution. I would like to also change the boot priority to boot from the cloned SSD but can't seem to get there on BIOS.
XPS 8930, help with replacing SSD boot drive
