I bought this PC new about 6 months ago, I've already returned it once as it was not charging and they replaced some AC connector or something. I've noticed that the fan seems to be almost on continuously even if the machine is not under load, say just typing a mail as I'm doing now when it's been started up from cold (i.a. not been in use for hours). CPU usage is sitting a about 1 - 4 % and I don't have any disk activity or network traffic. I noticed that if I'm say on the BBC News web site and watching a video clip, the cup usage will jump to 100% and the video becomes unwatchable with jerky video performance and the sound is broken up. I noticed the same if I try to play videos or sound from the local co drive, it's unusable if I try to network stream anything. I have called Acer and they've given me a ticket to return it on possibly for a repair but I just wanted to know if anyone had a solution or experienced similar issues. Thanks in advance..
