hi guys ive been trying to fix this issue for days and im stumped i cant seem to launch portal 2, CSGO or fallout 4. i click play it says preparing to launch then it says its running before it says synching then back to normal all without ever Running the game, no game window ever opens during this process help? ive tried steam forums and stuff about this but i think i can rule out old drivers verified game files and other software intervening as the intervening software list is long and includes software ive used for years and for years i havent had any problems with them so for whatever reason those programs are on that list arent problems i am facing as this started 3 days ago. help?
