Windows extremely slow after powering down during Windows Startup Tool.
I had to use my Sata controller for something and this required me to change from RAID to IDE in bios. After I was done, I foolishly forgot to change it back to RAID and Windows Startup Tool started since Windows couldn't boot. I needed to print something urgently so I held down the power button during the repair since I couldn't cancel it. I changed it back to RAID and then booted into Windows. Ever since my computer has been extremely slow. Does anyone have an idea what this might be and how to fix it? All I can think of is Hard Disk defragging, but again I have no idea. I might reinstall Windows, but I want that as a last result. Thanks.
