My buddy just recently purchased a pre-built pc from Newegg. It has a Gigabyte 1080 GPU , i7 6700 cpu, thermaltake 600 watt psu, 32gb (16x2 gb) of no name ddr4 2133 RAM and some asus micro-ATX motherboard ( not sure on the name but when I looked it up prior, it had poor ratings.) He's been having issues when he hits the windows button to minimize games like WoW or Diablo 3 and his system freezes for anywhere from 1-2 minutes and then continues. During that time he can't access any programs and is forced to wait. He didn't have this issue when he first got it, but after a month this all started. What might be the issue and how can we fix it?
