hey guys, there is one problem i cant seem to understand ?? well the story goes, i bought a maxtor basics external hardrive for the desktop, 750 GB, with Vista Compatiblity. i had movies on some data CDs and wanted to put those movies into the external hardrive in case the data cds become stuffed up and dont work anymore. (BackUp of movies)(Cd's were burnt CDs.) i was putting the movie "the number 23" onto the hardrive and then it said "cant read from source file or disk". i tried putting it onto the hard drive from the cd 2 times, then i decided to copy it onto my desktop, about half way through, the coomputer freezed up. i forced reboot (turned it off from the button) then i turned the computer on again, then once the computer booted up, the computer frooze again. this happens a fair amount. but once in like 10 times, the computer will boot up properly if i close nearly all the processes from the task manager. then yesterday, i turned it on, then norton gave a message saying that it encountered a internal problem. so because of that, i thought norton was giving problems, so i uninstalled it. and before that, my uncle installed MYOB accounting Plus V16 onto my computer. and i also uninstalled it !! so is MYOB accounting plus v16 compatible with vista or not ? i have Vista home premiuem, SP1, 32-Bit now i dont understand why this happens, is it a virus, or just a driver problem ?? then I tried scanning my computer using bit defender, nothing was found. i went on PC Pitstop, and it told me that some of my drivers are old. i cant exactly remember which ones, but once i get home ill let you know. can anyone tell me what seems to be the problem ?
