Please Help

I posted this on /g/:
Does someone know what's happening?

Hello /g/ it's my first time on here.
I'm having a bit of a problem right now.
Well.
I'll just state the details.

My taskbar isn't visible.
I can't see any of my desktop icons on the screen.

The only thing I can see is my wallpaper.
If I restart my laptop it would be back to normal, but this usually happens after the taskbar goes white and blocky ( kind of like the old windows thing.)

It's been bugging me for a while.
Also I'm only able to access the web right now because Avast is open and I clicked Support then Check FAQ.

The browser closes sometimes.
Please help.
Feel free to ask questions.

Zathura is okay, but it's just for PDFs. It doesn't support DJVU, EPUB, MOBI, and the other myriad formats in my books folder.

There's a fork or extension or something that supports DJVU. To support EPUB, it would basically have to be a Web browser. That'd be better off as an extension for Jumanji or whatever it's called. It supports JavaScript userscripts, so there's probably a script already.
