When I purchased computer(2nd hand), there was a sound card in it, and my estimation is that it was an ALS120, and the System detected it, but I couldn't find a driver for it, and Wizard couldn't find it either. Therefore I decided to remove the Asound Card AS007 3D PnP card from my old windows 98SE and install it in the XP Pro. Now here's the problem. I took the XP and placed it on its side, removed the side panel, which gives acces to the card slots, removed the exhisting sound card, and attempted to install the AS007 card, but when I powered up and turned on the monitor, nothing would come on the screen. So I removed the card and placed the older card back in, powered up again and still nothing on screen. Removed that one, put everything back together, sat the computer upright, powered up and voila, screen comes on Welcome to Windows XP, etc.
Has this something to do with the fact that the side panel was not put back on, or because the chasis was sitting on its side.?
