Windows 10: HELP! Computer suddenly slow?

My computer was working fine on Steam when suddenly the screen dimmed, resolution jumped to 175%, and now everything's slow. I ran an antivirus scan but found nothing. Could this be a faulty Windows update? If so, how do I reverse it?

URGENT HELP NEEDED! HDD suddenly became blank!

Hey there, @Shamonto Hasan Easha!

I'd try re-plugging the hard drive and checking if the cable is damaged. I'd also suggest to try plugging the drive in another computer and see if it gets recognized properly there. Is it a IDE or SATA drive you're using?
If the drive is unallocated, this means that the partition has been lost after the power went down.
Check out this thread for more ideas on how to solve the issue. There are some detailed steps there that might be useful for you:

Hello-

In the last two days my computer is suddenly displaying the message 'low memory.' It has been fine over many months with zero hold ups even with multiple tabs open. I know when I just have too many tabs open slowing things down, vs a certain certain shopping websites

I ran Microsoft Security Essentials, Malwarebytes and disk check / scan last night -all with no change.
