I cannot access my personal computer unless i sign into steam! Does this sound stupid or what? Well it has all started when i was in the Dyson game. I was in settings and clicked on full screen mode and then the nightmare started. I was sent to a black screen with a box that said "Signal Unsupported" and no key on my board would work. I tried ESC to back out and nothing. I tried CTRL+ALT+DEL buttons and nothing. I finally had to turn off my computer and turn it back on and when i did the Steam login screen came up. Yes i could login and once i logged in then i could access steam and access any other windows 10 programs uncluding going online to you tube and facebook etc. So i thought this must be a glitch and i clicked on start and clicked on power and restarted MY PERSONAL COMPUTER and once again the Steam Login screen would pop back up as if it were my OWN PERSONAL COMPUTERS LOGIN SCREEN!!!!! I cannot access any of my icons or access the internet unless i login to steam! Now im trying to get my money back for a game that ive played over 1000 hours. And i suppose i could uninstall steam after i login to steam and take back control of MY PERSONAL COMPUTER. But htis sounds rediculas and stupid and yet it has happened to me. If anything this is a WARNING to all! Unless steam can help me with this problem i guess i can uninstall steam and take the $20 loss and say i got ♥♥♥♥♥♥ in the ass by steam!
