My sister always manages to mess up my computer somehow too, she's 12, but I don't hate her because of it.

lol just for that hate ur sis? then I would kill my brother for all his stuff :P but deep inside I really like my bros :D

I'll finish

I bet ur sister is Gballzack. 

 thats one hot sister you got there soriku

 this is Joel we are talking about here, you can figure out where he was going with that

I know a few people that have one or rather had one, none of them have ever had this problem. Sounds like your computer is possibly a spazz. I've seen similar things happen before sometimes the things go weird with no explanation even.. the only thing you can do is roll it back and fix it.

ok, don't hate your sister cause your not smart enough to reboot your computer and tell it to NOT go into safe mode. You should have just power cycled it and watched the startup and told it to boot normally.

For the record.
Windows will go into "safe" mode whenever it fails to boot properly, even if your the idiot who decided to pull the power cable while it was booting.

soriku's sister must be himself
