One day my 2 and a half year old mac book suddenly started to go really slow and the programmes were not responding too well. About a month later after hardly any use my macbook started to take for ages to start up. A little after that my computer would.npt let me log in and asking for my password again when the password was correct. Now it will not even load to ask me for my pass even thpugh I have let it load for about two days. Does anybody know what this is, how ot started and please how to fix it
Thanks
