I am using a GA-H61M-USB3V motherboard with an Intel i5 3330 CPU and ATI Radeon 7750 graphics card. My PSU is 500 watts
My computer decides to sleep at random intervals, these can be between 30 minutes to 4 hours.
As far as I know, my computer is not overheating. My power settings are on high performance and to never sleep.
I know a way to fix this problem however I do not believe this is a proper way to fix it.
I am able to fix the sleeping by disabling the power save modes in the bios peripherals menu for integrated graphics such as deep sleep options.
I am using my graphics card and not the integrated graphics and so I do not think that this should be affecting the issue at all but it seems to fix it.
Does anyone know why this may be happening?
I have also had problems with not being able to have any graphics when disabling the integrated graphics despite being plugged into the graphics card:
