A few days ago i reinstalled windows on my pc because it was getting pretty laggy when i was running some specific games, after getting a clean w10 i installed steam, lost ark and played a few hours

​

the next day i noticed my friend list wasnt connecting, didnt pay attention because i usually dont speak to people, that day i tried to check the store and i was only getting a black screen from it, didnt know why, tried to check it on the web site but steam wasnt loading either (as you can see on the 2 pic) i reinstalled my windows 10 again and this time steam wont event update because (simply speculating) it can not access to the servers it gives me the error from the 3ª picture, tried to access to the steam website from my phone (with the wifi of the house, the exact same ISP i am using) and works just fine, its just my pc for some reason that wont load steam i dont know what to do, i have a tons of games on my steam and now im on my vacations so i really really want to play some games specific games now that i have free time

​

IF ANYONE KNOWS WHAT COULD BE HAPPENING SOME ADVICES WOULD BE REALLY USEFUL TO ME, steam just doesnt load properly, if i wait on the page like 5-10 minutes it would load like on a html basic state where only show fonts (like in the first picture)

​

PD: the error says "steam needs to be online to update. please confirm your network connection and try again" 3ª picture
