Arrrgh, once again

I am terribly unlucky with computers. I have probably have a history of 5-6 computers, all ceasing to function for reasons that even boggle the technicians. Once my hard disc gave a loud crack and a sound of a loose bearing hitting the casing with loud and frequent "pings" went on until I pulled the plug on it. Another time, something in the cd-rom suddenly cracked, stopping playing the cd. When I took it out of the case and turned upside down sideways, only to see flakes of the stuff of the cd coming out like snow. The cd-rom had broken the cd down to its very shards (Tuz-Buz -salt, ice-  as they say in Turkish) and somehow managed to damage my hard-drive as well. I have lost all my academic papers and creative pieces. about 80 poems, and countless translations. Do I hear back up? I've had the strangest problems there as well. Either the backup cd didn't have everything or would not open, or the files came up damaged when I transfered it onto another computer. I'm seriously starting the feel I must have some cyber-jinx energy, or god doesn't want me to write, on a computer at least. 

To end this once and for all, I bought superduper Mac Book Pro, hoping my troubles would come to an end. After all, I have friends who have been using the same mac for years without any problems. Well, 10 months in using it, suddenly the damn machine refuses to turn on. I try everything in the manuals, then take it to the technicians. They tell me its cpu board is caput. This is, apparently a terribly rare thing, as they have to order one that'll arrive in a month from the States. I thought we were in the fast age, flying all around the world in days and all. What is this one month b.s.? 

Hopefully the memory is intact, maybe there the Mac can cast its counter-spell to my jinx. Maybe this time the measly number of files left to me from my last 10 years can be saved.
