Hi guys, I have an Acer M3802 which is randomly restarting. I've determined it's not software related as I've re-installed Windows twice, once with my own disc and again with a friends. There's no pattern of when it does restart but when it does, it sometimes restarts during boot a few times before it loads again. I've given the inside a good clean and applied new thermal paste to the CPU, and the max temperature is about 50 degrees which I've been told isn't hot by any means. The same for the GPU temp wise. The only thing that has changed recently is that I've add a 1TB for extra storage but could that cause the PC to reboot even though it's not got Windows installed to it? Or does anyone know how to test individual components through software? It's not the speediest of things but all I use it for is playing movies connected to my TV, the odd document and iTunes for my phone and iPad so don't want to buy a new PC or replace parts when I don't need to. Any help will be appreciated.
