NVIDIA G84, G86 faulty
Despite NVIDIA's claims, the Inquirer reports all, not just a select batch, of the company's G84 and G86 chipsets used in GeForce 8400M and 8600M graphics cards are suffering from heat-related failures due to an unidentified substrate or bumping material used to help make the video hardware. They all share the same application-specific integrated circuit (ASIC), which is the source of the problems, in both notebook and desktop PCs. The chips have been failing since last year, and earlier this month, NVIDIA said the problems will drop the value of its shares to the tune of 25 percent, and is budgeting $200 million for repairs.
