Slow boot up

Hi all!

Anyone ever experience slow boot up after a black out or brown out? I was playing a game on my system when all the electricity turned off--I have a surge protector. After I turned the computer on, the Windows 10 boot up became very slow--about 2 minutes. Then when I get to the desktop, I click on an app and it lags. For example, I click on my Steam app and it takes like 3 minutes to load. After about 10 minutes the comp seems to be working just fine. It's the boot up process that takes a while now Any suggestions? Thanks!

couple of other things:

in the search field type: "cmd", right click on it and select "run as admin"

a couple of commands to run are:

"sfc/ scannow" for system file checking for errors
"CHKDSK C: /F" to auto fix drive errors on C drive (you can change the drive letter for additional drives).

Hey! I fixed my problem but I can't remember if it was because I reinstalled my OS or because I replaced my RAM. I did those around the same time because besides Windows booting slow I was also dealing with blue screens caused by faulty RAM.

If you have multiple RAM sticks, try booting with only one of them and unless the problem is fixed try the next one. If that doesn't fix it reinstall Windows. Good luck.
