I have dell inspiron 700m. bought it around 2006, thus, my optical drive doesn't work anymore. about a month ago, after transferring files from my pc to a stick, it suddenly stopped working. it was still on but not responding. what i did was to force-shut down the pc. when i turned it on again, it only reached up to the start up, then it goes off again, then automatically turn on again, repeating the process.. anyway, i run the diagnostics, and it says that partition was missing or so. i wanted to reformat it, but i can't using the cd (no opticaldrive). i am now trying to reformat using usb but i had no success in doing so. hmmm, what do you think is the problem and how may i solve it?
