[SOLVED] W10 system freezes.

My Windows 10 machine is randomly hard freezing, the displays remain on but the PC becomes unresponsive and requires me to switch off the PSU. I gave the PC to my friend after building a new for myself, and i wiped the drives and put in a fresh Windows copy. Since then it has been randomly freezing. What should i do first?
