Hello windows 7 guru's, I was having performance problems with my pc, and decided to do a defrag using defraggler by piriform. Sometime in the process, my computer froze up, and then gave me a fatal error saying some type of .dll was missing and that windows must shut down.
Since then, windows will not boot. I believe it is not a hardware issue, as in accessing the bios everything seemed to running fine. In the boot up, it goes to the hardware monitor (like it usually does) then my monitor gets a blank screen. After a long period of time, The blank screen turns into half of what the windows boot looks like, with the microsoft corporation logo and a blank loading bar.
I do not know if the harddrive itself got damaged in the process, or just the software. Any guidance is appreciated!
