Building a PC can be problematic, then again pre-built PCs can come with so much crapware--it will take so much time cleaning it up that you may as well build one for yourself and as long as you don't install each part manufacturer's crappy tools (MB "tools"/Video card vandor drivers/etc.) you should be fine.
A good example is my current x470 motherboard from Asus, if I do any kind of fan control or overclock with the damn tool it crashes (not necessarily right away, so it took me a little while to figure out what was going on), now I can disable the tool from auto-loading, but I can't even un-install it, remove its files or services, this is beyond annoying. Before then I had an Asrock motherboard, the tools were more stable, but some features did not work (no crash, just no effect).
