I've finally had it with my old computer. It's freezing almost every time I try to save a high resolution work on Clip Studio Paint, most of my time I would've liked to spend on drawing went into waiting for it to save/process something and restarting. In the end I didn't get to work much, so what I did is order a much more powerful used Fujitsu laptop. It wasn't cheap, but I can't stand the lagging and freezing of my old PC any longer.
