Tablet shuts down when i click any app

I there , so i bought a bq edison 2 qc , it has about 3 years now and about a year ago i decided to root it and mess around with roms and boot animations and so on. The problem is that after i did this my tablet just stopped working correctly . It turn on but when i open an app it restarts . I've been trying to fix it for so long and im getting kind of annoyed because i cant solve it. By researching I've realized that i could solve the problem by flashing in the tablets original firmware but i cant do that either because my pc wont recognize the table . Also tried installing the newer drivers but it says its already installed.
Some help solving this problem that i caused stupidly would be very much appreciated
