Windows 10: Today, my PC suddently became slow. And I don't know why.

Today, a game operating system steam Broke for me, I tried multiple methods which included updating my drivers. I have a fairly good PC, so I'm unsure why it's running so slowly when it comes to games. Yesterday it was working just fine. Anyways, I fixed it via some method thru the app which wouldn't damage my PC. But now, it's been so slow that I can't run games and I'm stressing out. Does anyone know why this is happening and how to fix it???

:)

 

don't know what the problem is, but computer is really slow :[

Were you on SP3 even before the slowing-down problems started?

If not, I suggest you do a re-install using only SP2.

SP3 had some issues with AMD processors... (mainly consisting of pc rebooting, I dunno if you're getting that stuff as well?)

 

Windows phone 8.1 calendar and contacts birthday don`t sync

Yes, of course (to both questions). I suspect that the problem is due to the slow syncing process (I don`t know why it is so slow). I say that because the random contact I created yesterday appeared in my calendar when I connected to the wi-fi (today!);
but when I deleted it, it didn`t disappear not even now (after 5 hours from the last time I connected my phone to the wi-fi), although I tapped the sync button from my default account several times. Maybe tomorrow it will disappear

Is there any explanation for why this syncing process is so slow?
