Hi Muplayer, welcome to the board.
Have you monitoring the temps? It is important especially for a new build. Double check your cpu fan set well and thermal past is applied properly. Blow house fan into open case to see if problem persist. Check if SATA contacts are good; loosen SATA cable is known problem for freeze. Run some tests on the rams. Next thing to check is power supplys especially on unreliable brands. It these are not it, we figure something elses. Good luck and let us know what's up.

Post your system specs may help in diagnostic.
