Suppose I am using Ubuntu version X now. My USB port and optical disk drive are not working properly and I want to do a fresh install of Ubuntu version Y using the downloaded ISO image. Since I cannot install using CD-ROM or thumbdrive, is there any way to wipe out version X completely with version Y?

Just a suggestion. Repartition your drive to create a 2 gig partition (at least) install the ISO to this drive using Unetbootin in the type box change to harddisk and select the new partition. Then update grub and reboot. Select the new partition boot to the live image then install to the old partition. As I say its a suggestion don't know if it will work or what problems you may have along the way. But if it works it works.
