So when playing games I got alot of black screens, someone said to put the Power plan to Performance, did this and seemed to fix.
But I notice when I play let's say battlefield 3 for 3-4 hours, I get a black screen with a loop of the last sound played. If I restart PC and play again it can go for another 3-4 hours or it will last for 10 seconds untill I get a blackscreen again.
Usually if it happens 2 times I leave the pc for some hours and come back then it works fine again.
Go into the power profiles,
set standby, hibernate and sleep to OFF
leave the monitor standby ON, that's OK (maybe not, try OFF)
Set the Hard Drive standby to NEVER
Set system Performance to MAXIMUM, not "quiet mode."
Open the bios set up and make sure "cool and quiet" is OFF. (AMD)
There may be a performance setting in the bios setup you have...make sure it's cranked up to max.
in the bios, see that the allocation for video, if available, is maxed.
Now open the hardware manager profiles...
click system properties
click device manager
double click on mice and other pointing devices
right click on HID compliant mouse
left click on properties
click on the power management tab
UN-check the box that says: "allow the computer to turn off this device to save power." (there is now NO check mark in this box)
Now repeat this procedure for all mice, monitors, keyboards, and ALL USB ports on the device manager list.
You must open ALL the devices one at a time, as above, and turn off the power saver, for each device.
