when ever i play games like csgo league of legends and G Mod i always get a black screen/ sound loop, it usually ends up in me needing to restart the game/ sometimes my pc. it also happens with minecraft, but in this case i get a unresponsive game, it usually happens every 10-20mins and even sometimes as low as 5 minutes, im new to computers and all things like this so help would be appreciated

my pc information is - H81M-DGS motherboard Intel premium processor G3258 3.2Ghz 3mb cache 8GB DDr3 RAM 1TB HDD DVDRW windows 10 AMD Radeon RX460 2Gb DDr5 PCI-e graphics card
