On every boot up I have to adjust the gain on the facial recognition to get it to recognize me. I have gone into the command center and saved with the gain at 100%, but to no success. When I slide the indicator to 100% and select apply and ok, I believe it should save, but that doesn't happen.

I have an Studio XPS desktop that won't boot into Windows, startup repair doesn't work, System Restore fails. I have run Dell diagnostics on the system and it's really strange. When i do the Pre-boot System Assessment the Hard Drive DST says Warning - Hard Drive - No Hard Drive Detected.

I currently have 2 GB RAM (1 GB X 2). I tried to install 4 GB more (2 GB X 2) and my computer would not initialize after power on. Is it even possible to upgrade this computer? Do the larger sticks have to be installed in the first to slots? I have never worked on a Dell and this has me stumped!
