Not sure where this should go so I decided Windows 10 would be sufficient.
For the past month or so my PC has been entering sleep mode wether I'm playing intensive video games or just browsing (however more often when in-game).
I ruled it out as an overheating issue as my GPU peaks at 81 degrees, CPU at 45 degrees.
Essentially the screen would go black but the PC would still be on, after about 10 seconds if browsing to upwards of 60 seconds if I'm in a game (ex. rainbow six siege). Afterwords the PC will either automatically turn back on or I will have to power it on, it leads to me clicking sign in and shows "resuming Windows" before continuing as normal.
At first I thought it was a faulty PSU as it was a 800 watt apevia that was known for failing and switched it with a EVGA silver verified 600 watt. For the entire day absolutely zero problems but the day after the issue resumed.
It started happening after I installed a reference RX 480 sapphire GPU, I've uninstalled drivers and re-installed them but it continues to resume. The PC was originally purchased from CyberpowerPC, which I regret with a passion.
Specs:
FX:8320 Black edition using a Factory sealed water cooler
RX 480 Sapphire (reference)
Gigabyte MOBO (will update once I run speccy)
EVGA 600 watt
Edit: previous GPU was a power color R9 270x, I will also like to mention that the first few days of the RX 480 being installed was perfect, after the Windows 10 anniversary update it also started occurring.
 
Hi comiclegregblade, Try going to Start>Settings>System>Power & Sleep>Additional Power Settings. In this window, change plan to high performance, and then click on change plan settings. Click on change advance power options. Expand the sleep option and check that all sleep and hibernate settings are 'off'. Click apply/ok, and then try testing the PC. Hopefully this will work.
 

Ive already tried that, numerous times actually by going into reg edit and unlocking more options. And it still occurs
 


Have you found what is the problem? Because i have exactly same. Please let me know if you find solution to fix this.
