You are having driver issues. Which ones I can say. This is why I will now and forever say the clean install method on Laptops is a waste of time. There is no gain to be had, only headaches. Some will swear otherwise but those same folks that swear otherwise will not accept my challenge to go head to head same machine, same benchmarks, same clocks etc to prove that the clean install did them any good. ASUS factory images have minimal extra software (so long as you didnt screw up and get a best but machine that is LOADED with bloatware). Takes about 5 minutes to uninstall the extra stuff. Ccleaner will not only uninstall it it will wipe it and remove all registry entries related to it.
My challenge still stands. 4 laptops to choose from, G74SX, G751JL, G751JY and G752VY. All have have original images that have been upgraded in place to win10 anniversary edition. The only machine I've done a clean install on is my current desktop build but that's only because there is no choice in the matter with a custom build. And guess what, thats the ONLY machine that has any flags in device manager although all drivers have been loaded. One PCI to PCI bridge says the device cannot find enough open resources. Thats bridge is assigned to the thunderbolt controller that Im not using nor will I ever use so its not a problem.
