I am running on a fairly low end system and sometimes my monitor just goes black and doesnt come back on until i restart my pc, It seems to happen when my pc is under alot of stress and i tab out, first time it happened i was streaming in discord playing mw and tabbed out, the next time i tabbed out while in game on eft. Wondering what the cause is since its only just started happening when there are plenty of times in the past where it didnt happen doing the same thing. Sorry if this seems dumb i dont know alot about computers and thanks in advance
