The front side USB slots are not working anymore and there was only
one remaining free USB PORT and that is located in the rear side or
rear port and it was that place where I plugged my flash drive that '
fried ' it. the USB ports adjacent to it are connected to other
peripheral devices which incidentally are working normally...
I am also wondering if its the fault of the flash drive due to sloppy
build?
Incidentally Both of the damaged flash drives were made by transcend.

Sorry
I am not willing to risk another of my flash drives on that
machine,,,,,
