Dell has pulled out of two major deals with IBM.
The company quietly ended a $16bn (£9.9bn) purchasing contract with IBM because Big Blue had sold off the divisions it liked to deal with.
A $6bn (£3.7bn) services partnership between the two companies has also been pared back by Dell.
The computer maker had bought hard disk drives, flat panel displays and various chips from IBM since 1999.
Company spokesman Bruce Anderson said this week that Dell's relationship with IBM had ended because of IBM's selling off of many of the businesses it had been working with.
Last December, IBM sold its hard disk drive business to Hitachi for $2.05bn (£1.3bn).
