Windows won't detect card

PC crashed while playing Warframe, now Windows won't detect that my card is installed. I just updated to Adrenalin Edition 18.6.1 last night and haven't launched Warframe since, so I assume this is related.

System Configuration:

**Motherboard**: MSI 880GM-E41

**CPU**: AMD Athlon II X3 455 Rana 3.3GHz

**Memory**: 16GB G.SKILL Ripjaws DDR3

**GPU**: ASUS Radeon R9 390

**VBIOS**: n/a (Windows doesn't detect my card)

**Driver**: Adrenalin Edition 18.6.1

**OS**: Windows 10 x64 (17134.137)

Steps to Reproduce:

I'm only guessing that updating my AMD software version is related, but it seems likely. I went to C:\AMD and the latest version, before 18.6.1, is 18.2.3. I assume that means I was on 18.2.3 before the update.

Expected Behavior:

PC recognizes the card (and therefore my monitor).

Actual Behavior:

Right now the only way I can access the machine is by remoting in. Even when I do that, the Radeon Settings app won't run because it doesn't think I have a Radeon card installed.
