Hello i have a problem with my pc, when i turn it on everything is good it open and work correctly and monitor too, after few min even if im not doing anythings hdmi signal turn off and the pc is freezed the reset button wont work either, if i shut it down at the switch where the power cable plug in and restart it it do de same or sometime monitor wont have signal at all. Cable are good and monitor is good all work on everything else, ive made update for everything with drivereasy and i play for a full night, next day same thing happen but now hdmi signal is lost soon as Windows open (sometime motherbord is very hot ).
The fact that the monitor works sometimes and not others makes me suspect the monitor drivers. Try uninstalling/reinstalling them: Open Device Manager by typing devmgmt.msc in the Search Box in the Taskbar at the bottom of your screen.In the Device Manager window, scroll down to the entry for “Monitors.” Click it to expand the list of drivers.Right click the drivers and select “Uninstall” from the popup menu. Then, restart your computer. Windows will automatically detect your monitor and install the drivers it recommendeds.
It’s probably your display controller on your motherboard which means that you have to get a new motherboard
Check the fan. May be obstructed .or heat sink on processor .
