Greetings fellow Eorzean.

Usually, BSODs are a sign of either hardware or software failure. If your Windows installation is unstable, the best thing would be to reinstall Windows from scratch for testing to see if the computer regains stability as this will eliminate the factor of the software being corrupt. If not, it's possible that one of the hardware components may be bad such as a stick of ram, cpu, video card, or even the hard drive. We recommend checking with Microsoft support regarding the BSOD error code you are getting to see if they can help with pointing out what may be the problem.
