I have been using my computer completely normally for the past week. About 2 days ago, I noticed an issue where, after I authenticated with an external biometric reader, it would say "Welcome" for way longer than it normally did. Afterward, it would show a completely blank light blue screen for about 30 seconds. Following that, it would boot into my desktop like nothing happened.
I have used the biometric software for well over 3 months, and I haven't had an issue with it before.
Computer specs:
Gigabyte H170M-DS3H Motherboard
Intel i5-6400 @ 2.7 GHz
Sapphire Radeon RX 480 Nitro+ 8GB GDDR5
64GB Corsair Vengeance DDR4 RAM
EVGA 500W Power Supply
WD Blue 1TB @ 7200RPM
Samsung 840 EVO 500GB SSD
Windows 7 Ultimate
I could Ctrl+Alt+Delete on the blue screen, and start the Task Manager, but I didn't see anything running that shouldn't have been. I do have a backup from before the computer started acting up, but I would prefer to not have to resort to that, if necessary.
