I have had to re-install a customer's Dell Optiplex GX520. It did not come with any drivers CD so after the basic re-installation of XP I had to go to another PC and download from Dell's site all the drivers for the particular PC model. I started with the ethernet driver and got the internet connection going and re-connected to the domain. However at one point I was doing a Windows Update and also carrying on installing drivers. One of the was for the BIOS. I remember it asking me if I wished to upgrade from version x.x to x.y and I confirmed I did.
AT some point after this I was prompted to re-start the machine. As it was powering down it hung with a plain blue screen. Eventually I was forced to switch it off manually. Since then it will not re-start. 1 - 2 seconds after pressing the power on switch it issues a series of buzzes and hangs. It shows no messages on the screen at all. The scrfeen remains black. I have a feeling that the BIOS update has caused this. On the assumption that is the case is there anything at all I can do about it?
