Hi I had a power shortage and when I switched the PC on (it's a Dell running on PC) I got a message that windows needed to shut down. I turned it off and got the blue chkdsk screen saying it is checking file system C, it's NTFS and the volume is dirty. It run stage 1 in minutes, stage 2 has now been running for 16 hours and is still on 2 percent. I have tried running it in safe mode, command prompt but it won't do any of them so I am stuck with the blue screen at 2 percent and don't know what to do next. Can anyone help? I am not particularly techno savvy.
