Powered off during update (dumb). Worked fine but gave me trouble starting afterwards. Same night- asked to do updates while plugged in.   Allowed updates for the night.   Next morning- black screen, lights work, tried repowering numerous times, got 7 consistent beeps-beep code.   Pulled battery out, put battery back in and powered up fine.   Tried to power and only the fan would run and light code,   but didn’t acknowledge battery charger with the light.   Tried to start numerous times and didn’t work.   Called dell- they said to take batter out and discharge, start in safe mode, hooked up to monitor, etc.   Nothing worked.   Took computer apart to pull out battery to reset bios.   Computer worked upon putting everything back together.   Reinstalled windows with dell drives.   Gave trouble starting up.   Crashed after complete start up.   Eventually got it to start up and reinstalled windows with windows drivers. Ran component checks and almost any other checks you can think of.   All checked out.   Worked for 2 weeks.   Went to power up- loaded dell screen, computer automatically powered off at initial windows loading screen.   Tried to power again: got 2 options (repair or normally) tired repair- failed, tried normally-failed, pulled battery out and discharged with power button and it automatically ran a chkdsk then loaded windows and functioned completely- Which is where I am at now.   NOTE*:   Computer seems to give start-up problems most generally when I move it from my dorm to the library or vice-versa.

PLEASE help me.  What do I do? I am so lost.
