As previously mentioned, Thunderbird & Firefox randomly freeze & don't respond. This happened once with File Explorer. Yesterday was a new problem but may be related. I could not access TB email or use FF because the bookmarks were not accessible. Yet everything was working a couple hours earlier. I have both of their profiles on the D: drive.
I rebooted the PC and the D drive did not show up in File Explorer or Disk Management. I shut down the PC & did a cold re-boot. I message came in large text on the lower half of the screen but it disappeared before I could read the whole thing. Within a minute everything came back up & running normally & the D: was now there.
Almost the same thing happened a month ago. Back then I could not copy to the D: drive. Rebooting indicated it disappeared. Another reboot gave me the large text error message & everything worked after that. Except for the random TB & FF freezes and the one time where File Explore froze.

PC has an ASRock B365M Pro4 mobo, Intel I5-9400 CPU, 16 GB RAM (2 x 8 G.Skill RipjawsV) & a Samsung 500GB EVO 970+ M.2 for the C: drive. Corsair CX430 CPU, no video card. I built the PC last year but didn't start using it until about a month ago when I installed a Samsung 1TB EVO 970+ M.2 drive for the D: storage drive.
I did contact ASRock & they said these Samsung drives are good to use with that mobo.
Windows is 20H2 and restored with an image a day ago. The only programs that I installed are TB, FF and AOMEO backupper.
About a week ago I ran sfc /scannow & it said it repaired/replaced some files & the PC worked OK for 5 days which is the longest it has worked without have TB or FF lock up. I have to power off the PC in order to close out of the programs.
Before I restored an Image I did have Samsung Magician installed & ran SMART and everything was OK. Both drive temperatures were about 35°C.
I don't know if the D: drive is defective or if Windows just forgets it's there.
Is the large text error message from Windows or BIOS?
Any help would be greatly appreciated.
Thanks.
