Open the bios set up and make sure "cool and quiet" is OFF. (AMD) 
If there is a power saver or a "quiet mode" in the bios, shut it off... 
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 start 
click computer 
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) 
click OK 

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. 

NOW turn all the security back ON. NOW open your security antivirus. Make sure the antivirus is set to "gaming mode." Or "multimedia mode."
This prevents the security updating from interrupting your game / multimedia priority.
IF the security does not have "gaming mode" or "multimedia mode" get different security.
IF you are using "free" security downloaded from the internet, get rid of it NOW.
Use ONLY professional all in one security. DO NOT load multiple mismatched security programs, which conflict with each other.
DO NOT load free tools into your system such as: "driver sweeper" or any of that "free" goofy stuff.

Then re-test and let us know.
