  1. On my own I had already tried rebooting, and attempted to update the Realtek PCIE CardReader, but neither had any effect. My PC still didn’t recognize that I’d inserted an SD card at all and the Realtek PCIE CardReader still showed up with the yellow triangle and exclamation point in the device list. I got to “Method 2: Run Hardware and Devices Troubleshooter” and chose to Apply the fix. I restarted, as required. No effect. Moved on to “Method 3: Update/ Rollback Realtek Card Reader Driver” as I had not yet tried rolling back – imagine my surprise when there was no longer a “Memory technology devices” listed much less the Realtek PCIE CardReader that was supposed to be listed under it. Great. The fix was to remove it altogether? I had also tried downloading the driver from the Dell site, but that wasn’t helpful as the device is gone. Now I don’t know what to do.
