A many thanks to anyone and all in advance. Additionally, I apologize in advance if this is the wrong subforum for my thread.
Before I went to bed the other night, I started running defraggler on my old laptop with the shutdown option selected. Upon the next day, I turned on my laptop to find it booting to a black screen with a mouse. I tried running startup repair, which was unsuccessful. I also restarted and rebooted the laptop multiple times to no success. I read some info on other forums on troubleshooting that seemed helpful; however, I am choosing to ask for help here via my thread instead of attempting any of the aforesaid alternatives.
The laptop does boot into safemode with networking.
Thank you very much to bleepingcomputer for hosting such a site and to anyone, who reads this and/or might try to assist me in this issue.
