Hello, My problem is a weird one, often (but far from always) when I start up my PC, at the bios screen when it's still booting, it suddenly starts making these horribly loud beeping noises. The only way to stop them, is to hold down either mouse-key's, but this doesn't work for more than a few seconds. Eventually, the noises stop and the computer moves on to a screen where I have to tell it to load Windows 7, being the only OS installed on the PC. Apart from that issue, the PC runs just fine. I have noticed one other thing that may be connected. These past weeks, the PC has always had 1 update to install whenever I shut down, and I remember that the PC got stuck installing a particular update some weeks back, and that might have been before the problems began. My PC is running windows 7 ultra 64 bit, it's an intel dual core processor, with an ATI graphics card about 6 gm ram, but apart from that I wouldn't really know my systems specification. I could copy-paste a dx-diag into a post if that would be helpful.
