What you do is go over the machine in detail about BIOS, drivers and re-do heatsink work and clean it up. If it still hangs you know this machine well enough to see if it's mixed memory sticks and/or another new motherboard call.
Again, a common sight at repair counters. Machines like this are usually just a few years old.
I have the following problem on my PC, it happens more and more frequently, at least twice a day, the PC simply blocks, it does not give any error message, there is no information in the event viewer, it simply blocks, mouse and keyboard stop responding, it only works again after pressing the reset button.
I have checked the temperatures on the HWmonitor and are normal, values on the desktop.
Board between 27 and 40º
CPU between 8 and 20º
Graph to 40º
I suspect it might be from the power supply, but I would like other opinions before buying a new one.
I've also done a system reinstallation, I can be hours to play and nothing happens, I can start playing another game and it blocks after 2 minutes.
Also it happens to be playing and everything is good, left the game, open the browser and block, it is really very strange and I am trying to find a pattern or error message, but neither does it appear: | Razer (blackwidow) and when this happens, the keyboard light remains on, but does not respond to any commands, windows key or CTRL + alt + del, the Logitech mouse light is always on and the mouse does not move.
