Temporary Black Screen after logging in, with Working Mouse and Responsive Programs.
**EDIT: [I DONE DID FIXED IT, posted here for posterity. I needed to disable the service Web Account Manager. Solved the problem.](https://xkcd.com/979/)**
I'm having some unusual behavior on startup, and it's making me a bit of a crazy person. I'm self-taught (read: a moron) and I've more or less run out of ideas for how to fix this issue.
First, my specs: [PCPartPicker Part List](https://pcpartpicker.com/list/Yhc8NQ)

I'm using Windows 10.
**THE PROBLEM**
When I boot up my PC, I go to the login screen just fine. However, when I log into my profile, it just takes me to a black screen. [Here's a screenshot.](https://imgur.com/a/EUfEe4L)
What I find weird about it is that I can press the windows key to open up the Start Menu and start programs with no problem, but this black mask obscures everything. I can go to the Ctrl Alt Del screen with no problem, but opening up the task manager doesn't do any good, because of the obscuring black mask. [Screenshot.](https://imgur.com/a/1EZ8aKV)
And, after about 3 minutes, the black mask goes away, and I can go about my business. Before this problem started, my PC could go from off to browsing Reddit in about 15 seconds. Now, it's about 3 minutes. It's not an urgent, life-destroying problem, but it's pretty irritating.
**WHEN DID THE PROBLEM START**
I'm sorry to say that I have no idea. It's been doing this for a few months, and I've had this computer for about a year. It just happened out of the blue, and I have no idea why. I wish I did; that would make diagnosing this problem a lot easier. One thing I can say is that I haven't changed the hardware in that time. I have vague memories of it happening around the time a windows update was installed, but I'm not certain of that.
**WHAT HAVE I TRIED**
I've tried the following: Turned off all startup programs. Using different monitors. Pressing alt-F4 on the Black Screen of Irritation (it went bloop). Updated my various drivers including the GPU. Rolled back windows updates. and rolled them forward again when that didn't fix the problem. I've unplugged it and plugged it back in. You never know, right?
**WHAT HAVEN'T I TRIED**
I haven't updated my BIOS, I haven't factory reset windows, I haven't one anything that requires opening up my tower.
I'd appreciate some help. I tried to be as detailed as I could, but if you need anymore information, just ask.
