I have had my visa laptop for about a year.It is a vista compaq presario f500. Lateley i have spotted viruses on my computer.I Previously have downloaded many legit softwares to scan my computer then remove what they can.Some said i have 2threats and 69 infections, another said i had over 200 problems with the registry(idk what that is) and im rly fustrated at this point.Now my laptop has starting problems.It rarely works opperates starting up like its suppose to.It continuously restarts after u press the on button once.So now if i get super lucky it will load until it gets to the screen where it says windows error recovery. then sometimes i press either launch start up repair(freezes) or start windows normally(freezes)if im really lucky it will work like regulary then freeze 10mins later...Please help me whoever can christmas is tommorrow.What a great gift it would be for my computer to work...
