I have been getting this issue most of the time when putting my pc to sleep the screen goes black and my pc is unresponsive and i am unable to wake it up but the lights in my pc all stay as do the fans, it gets stuck like that for about 5-10 mins until eventually it shuts down, when i turn my pc back after this its as if i had asked it to shut down not sleep and i just get a normal boot. I can hold the power button down during the time its frozen and power it off and just power it on again normally. I have made sure none of my peripherals are stopping the pc from going into a normal sleep schedule and I believe its some software or a windows issue, any help would be appreciated.
