Question stream games need verified every time pc goes to sleep

hello all of toms forums, i'm starting to go insane with this starter PC i built for student at a friend of mines school they teach at... the system did amazing during my test trials and everything, but now he is saying every-time the system falls asleep or he puts it to sleep not shutting down but only going to sleep. he has to re verify any of his steam games. i took a look at what he was talking about and it's just that.



if the system is put to sleep at all, in order for him to play games like csgo or h1z1 anything like that. he has to re-verifie the game files. other wise it tells him that steam vac cannot veryify his account and i have tried uninstalling all of steam and it's files/games reinstalling and it happens everytime.

so basicly valves anticheat breaks during sleep? did you try reinstalling steam?
Yes steam was uninstalled and reinstalled from scratch.
Nothing else lose any memory I don't think it's a ssd issue otherwise windows would be bugging out as well as gpu drivers glitching and the hole thing as a unit seems fairly solid no glitching in web browsing or watching blu ray disc... No issue other then steam in sleep mode, and again shut down doesn't have a problem.
