PowerSpec pc Freezing and Buzzing noise while gaming

samstr

I recently purchased a powerspec G453 and have been playing games on it for about 4 months now. The pc has performed well in games and I have had no issues with the pc until about 2 months ago my computer would randomly freeze and making a loud buzzing noise. I lost all input and the only way to fix it would be to restart my pc. I have monitored my CPU and GPU temps, made sure my drivers are up to date and monitored parts and haven't found anything out of the ordinary with the computer. Any ideas what this could be and solutions for the problem.
