Yesterday I discovered my computer will no longer read my flash drives, external hard drives or SD cards. If I plug in any of them, they don’t even show up in Disk Management. In Device Manager they will show up, but will have a yellow flag and under Properties it says the driver for this device is not installed even though they’ve been used before on the computer. Clicking “Update Driver” doesn’t help because it searches and says there are no drivers for this device. If I go to the “Events” tab, it gives the date and “Device configured (null)”.
I restarted my computer today, hoping it might correct this problem, but when restarting I ended up with a message about an inaccessible boot drive. After going into a loop several times where it told me about the inaccessible boot drive and then restarted again, I finally ended up with a screen that gave me more options for troubleshooting such as doing a system restore point. I had the computer perform a system restore and finally it took me to the welcome screen and then desktop. Anyway, rebooting did not correct the problem about my computer not reading my flash drives, external hard drives or SD card. Any ideas? Maybe the problems I’m having are related to a recent Windows update (computer seemed to be working fine before the update), but don’t know for sure.
My computer is an HP desktop, Windows 10, Intel Core I5 6400T CPU, 64 bit operating system that was bought around the end of 2016.
I've scanned with Malwarebytes and Norton but nothing shows up.
Sorry, I’m no computer pro so I’d appreciate it if any explanations were kept really simple! Thanks so much!
