Major PC makers including HP, Dell, Samsung and Lenovo have stopped selling some machines because of faulty chips called Cougar Point from Intel.
Seven computer models by Samsung and four of Dell, and laptops and desktops from Lenovo and HP, used the faulty chipset, which enables the central processor to communicate with other parts of a PC, BBC News reported.
Intel reportedly said it has distributed approximately eight million faulty chipsets so far, out of which only about 100,000 had been put into finished systems.
The manufacturers have offered refunds, replacement parts or new machines to the affected customers.
Following this bug discovery, HP has cancelled an event in which the company planned to launch a range of business laptops equipped with the faulty chipsets.
Claiming to release the fully working version of the chipsets by February end, Intel was quoted by BBC as saying that it had already stopped producing the faulty part.
