Hi. I unwisely clicked on a Facebook link and was taken to a page which I was unable to leave. I finally turned off the computer and when I restarted it the screen just showed black with the cursor. After Googling the problem, I've tried system repair, system restore, restoring in safe mode, changed SATA to IDE, taken out the battery and depressed the start button, and changed the Boot order but none of these have worked. I can't access my antivirus/antimalware packages. It would be a personal disaster for me if I'm forced to return the laptop to its initial state as I've only backed up some of my data. I would be grateful for any help/advice. Thanks.
