I have an Dell Inspiron 5100 laptop. The problem is that when it boots up, it keeps making a loud beeping noise. Also, when I actually on the desktop, HELP AND SUPPORT keeps popping up and prevents me from opening anything.

Whenever I open any kind of program, the help file for them keep spamming me. I thought it was a virus or malware of sorts, so I ran an antivirus, found nothing. Then I try reformatting it and that did nothing. The laptop also ran sluggish and hot.

Dell support is not good at all. What might be the cause of these problems?
