Bad news ._." (read please)

Yesterday my cat killed a pen from an old tablet (which model is no longer sold in our country), so I was urgently forced to buy a new tablet. I am happy to buy a new tablet (although the tablet has already been used by someone before, specifically it was a person from game dev who almost did not use the tablet for work, so he sold it, and I bought it, its condition is almost as new - you can see the photo).  Old: Wacom CTL-471, New: Wacom Intuos Pro PTH-651. I thought that my problem was already solved, but today I again faced a problem..

Today my computer's motherboard is dead.  It just happened, and at the moment I'm trying to understand what exactly is the problem.  But I stil think that this is the motherboard problem, because it already was little crashed (its sound part was already broken last year, and we were forced to put the sound card in an additional slot)... Now we are doing diagnostics of the entire computer.  And I'm not sure when I can access it again.

  Now I have done almost all the work for January (exclusive works), but two works are at the background stage now, and I just can’t finish it now,. because I can't attach a hard drive to my laptop. I don't know what to do, now I only have access to the laptop, but it has a terrible color rendering and I just can't finish working on it (it very much distorts the color and light) .-.  

This week was just terrible for me, the world seems to be mocking me now. I will take the computer to diagnostics tomorrow, I really hope that I will be back to work very soon..  Really sorry for this, I really didn't expect this to happen. I understand if you want to unsubscribe from me. But as soon as I get access to the computer again, I will send the archive as soon as possible. Now all this is on the hard drive, and I just don't have access to anything. Hope for your understanding... +Even today I was a little sick, I really hope that it will not overlap, I am very upset now ._____.

UPD 07Feb20:  Results: We rebuilt the computer again, two memory slots do not work in the motherboard, they are out of order. We connected the memory to the other two slots (spare). Video card: it has a broken cooler, but it still works. Because of the last update of Windows, my BIOS failed in some moments, it just stopped loading Windows further and gave an error. Now the computer is in a very strange stage, I still want to take it to the test (more detailed), because I do not know what to expect from the computer in the future (PS I used Google translate, so sorry for my English)
