time to change - MAC

It was my desktop which was bombarding me with problem and lots of trouble.
Few days back i have a brand new handsome desktop after formatting it. Then everything works well until the first attack came yesterday morning when my sister switched on the desktop and realised a big welcome note which said " windows explorer has encountered a problem and needs to close" and im bounded to only two options - send error report. don't send. And yeah, there is one too, the restart button. All toolbar and startup icon seem to dissapear from its usual position, left the lonely desktop wallpaper seeking for its friends.
Then i started googling to see if there is any similar victim throughout the world. Google-is one main thing in this world i cant live without. I wonder how did i go through my secondary days without it... glad i survived.
The first prob here is solved after hours of surfing n browsing the net, trying out a few solutions which did not work, and finally ended in this site here which solved perfectly my troubles. -posted by Rohit.

Well it was perfect at first until my sister, yes again her, complaint that the windows firewall just could not turn on. So again, i start to google with my lappy. Then another prob came into the picture when my internet connection icon is nowhere to be seen and is taking me years to open the network connection and nothing could be displayed. Getting real pissed, i gave up googling, n tried smtg rather easy - system restore. ahah yeah..i know it was quite stupid for not using this in the first problem. Same result -Perfection, except for some missing programmes and files that my sister downloaded a day after the computer is restored to. Yet, it is already the best solution for the currect condition. Free things cant be exactly perfect you see.

It all went well, with her (refering to sis) surfing n playing the pc,,and until after dinner.. while i was washing the whole stack of dishes in the kitchen, she approached and again, bringing another prob... she neva bring good news i think, not until she does well for her stpm?? lolx

This new prob here is named ' unable to logon to windows'. Big prob!!! I guess is due to a recent auto window update, window sets an unknown default password to all the user account in the pc. -the admin and my family account. deep trouble, i could smell from the kitchen.
Tried hard with own-created-passwords like password, admin, administrator, chong, window, bill gates..nonsense..., hopin that one of it could strike the default password,
in the end..all failed. this is pretty logic, cos if it hits, i wud go for 4D on the exact night.
SO went on google again and tried many many solutions. Things are ain't easy as my cd rom givin another trouble and that definitely add to my stress... my cd rom couldn't read the cd. Whatis...!!~~!! Looks like i have got a lot of shopping to do in the coming pc fair.
.the night wasn't on my side, i failed trying diff methods. So that ends my horrible night and im saving all that trouble for the next day@ today.

This mrng, i started by selecting the 'last known confg that works' hoping that it will rub off all my nightmares, n sadly, if life was this easy, there is of no need for a doctor. Then my work on the google gets on..trying to see if i cud do a brute force attack on any of the account password. So i thought of having it to boot from USB insted as i have got no other selections since the cd rom is out of service, n i dun have floppy A slot in my lappy. But booting from USB flash drive is another problem, check here and you will understand why and i think my p4 desktop is not compatible for this feature. Hence, I google for other methods to see if there is any better and easier medicine before i decided to format it again. Lucky enough, i came to this site, -Thanx Mr. Vic Ferri.

Dear google,

you made my day and definitely painted my 'never give in' spirit more colourful than the rainbow.
