Buttom Case

my hp laptop is messing up!!!?
ok so i started my laptop regularly and then something pops up saying deleting files so i hold down the power buttom and restart it and now my files are deleted and my limewire isnt working and i dont have adobe flash player or anything so then i do a system restore and now when i start my computer something pops up and says start windows regularly and other stuff and after i press enter the log in screen doenst pop up its just a black screen so idk if i should buy a new windows disk or something cause if thats the case i might as well buy windows 7
call hp they are 24 hrs. They will tell you what too do about it!
Good luck
Too me it sounds like it could be a virus. That happened too me before.
