Yup its a bad unit. I had this one and I replaced it within 2 month of usage as it was causing random pc reboots.

I've mentioned taskbar in my comment too..
Edit : Actually the main reason for organising shortcuts in taskbar is for clearing desktop right...?So my comment is not completely out of point ?
Dude the case with pre installed RGB including fans are expensive and do not come under ur budget (35 -40 $) So best way is to buy a decent case and use rgb strips.
Edit : Case with side panels.
If u are changing to 1080 its a good thing. 1060 3gb is a sort of bad option. Try changing to an SSD of 240 GB as the price difference is small and it gives more storage option for your programs.
