Windows 10: Computer suddenly lagging

My computer recently started lagging whenever I use the computer. task manager isn't telling me anything as the cpu is 30% or under at all times during this lag.


I have a Windows 10 home computer HP build 19041.

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:
