Computer hardware died oddly with fault (6)
I believe the answer is:
device
'computer hardware' is the definition.
(I know that computer hardware can be written as device)
'died oddly with fault' is the wordplay.
'oddly' means one should take alternating letters (letters in odd-numbered positions).
'with' is a charade indicator (letters next to each other).
'fault' becomes 'vice' (I've seen this in another clue).
The alternate letters of 'died' are 'de'.
'de'+'vice'='DEVICE'
(Other definitions for device that I've seen before include "Gadget made for particular purpose" , "Gadget, tool, piece of equipment" , "Appliance, gadget" , "Thing made or used for particular purpose" , "Appliance; scheme" .)
