Solved
Battlefield 4 causes my computer to freeze/crash.
After deciding to uninstall the game in late 2014 (due to too much crashes etc.), I decided to download and install the game again yesterday. Sadly, instead of Battlefield 4 crashing it's now crashi...
Yes, luckily I have been able to fix the issue.
After checking all the hardware and software I noticed that my voltages were 'too low' (in a range of 92-95%). This caused me to buy a new PSU, as my older one seemed to be a cheap and bad one, which seemed to fix the Battlefield 4 related issues (and some other random crashes here and then). The ranges of my voltages are now around 100-105%. If it wouldn't have worked I would've also replaced my Motherboard and CPU, luckily I wasn't forced to so I saved a lot of money.
So thanks for the help for going through all the possible problems, yet the problem was at 'the source' all the time.
