I have had an AMD Athlon 1800 processor for about eighteen months and, until recently, when booting up this is displayed on screen. In addition, I have a printout of a six month old Belarc Advisor report which confirms this. For the last two weeks the screen on boot-up now tells me the processor is an Athlon 1150 and I have run Belarc Advisor which now also says this. Can anyone throw any light on this? (it would be best to regard me as a computer dummy).
