I have strange problem. When i move a cursor after 1-2 minutes of not using pc it starts few error sounds. But there are no new windows or something. Please help because its very annoying P.S sorry for bad english.
What OS are you on? Are your drivers up to date? Is your BIOS up to date? Do you have a clean system?
Did you adjust some energy settings to a very narrow window in terms of saving battery e.g.? I can imagine that 8 complains with fancy sound
All drivers for YOUR machine are loaded as available from your machine's manufacturer or you simply let it run as came with W8 drivers?
