Computer issues

So yesterday my PC's motherboard got burnt which I find really frustrating. Since then I haven't been as consistent as before when I have it I dont really know what to study on im panicking because it doesn't feel right to stop studying for that long we dont even have an extra laptop or something I can use on top of that I am taking online tution so idk what to do it's really annoying I tried studying from my phone but it's just not the same.
