stupid XP problem

been plaged by continuous PC problem for weeks/months
first the HDD died, then of cos i buy another HDD
then the power supply box blow... causing an awful burning smell. so i had to buy another box.. haiz..
so i thot end of my problems..
and now... blue screen is my constant visitor coupled with with sometimes this irritating message
".exe . There is no disk in the drive.
Please insert a disk into the drive\Device\Harddisk 2\Dr4."
waliao ehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

but managed to fix it with some help from here

this is after like re-formatting the bluddy HDD like every week.. cos it always terminates whatever i am doing without warning... and after trying for a few days.. i will always surrender and reformats it..
so ok, enough is enough, time to look for another device.. hmm, maybe a lappie..
