I had to do a clean install of Windows XP Pro on my home computer recently and everything went just fine, but it seems that the computer will not boot up unless the Windows installation CD is the in CD-Rom drive. Nothing has changed with my computer hardware wise, and this didn’t happen when I first installed windows on this computer. I’ve tried reformatting and reinstalling but it doesn’t help. Any suggestions would be great!

A family member has a failing computer running XP Pro whereas I have a spare drive on my own computer with an unused XP Pro installation already set up. My idea is to back up all his files/folders etc using the Back Up facility within Windows Live OneCare and then set him up on my spare drive. All XP installations in this house have passed Microsoft validation however, he does not have an installation CD but I can get his Product Key. I have two questions. What is the best method of preparing a computer for a fresh installation of XP Pro (is formatting the HDD too extreme)? Secondly, if I use my installation CD to re-install XP Pro on his computer but when the time comes to enter a Product Key, I enter HIS Product Key rather than my own, can that work? Are Product Keys only specific to the program/application being installed or are they specific to the individual installation CD being used?

We had a virus problem last month. Our Kaspersky 6.0 wasn’t able to detect the virus because it’s not updated, we didn’t have internet connection until last week. The virus had corrupted important files of some applications and we ended up having trouble installing new softwares, so we then decided to repair the OS using the Windows installation CD. It went well. Programs are now running smoothly and we’re able to install new softwares. But here’s the problem: WMP cannot play audio files. We get this error "Windows Media Player cannot play the file because there is a problem with your sound device. There may not be a sound device installed on your computer, it may be in use by another program, or it may not be functioning properly." Volume control is also missing from the system tray. In the Device Manager, there’s a yellow exclamation mark on "Realtek High Definition Audio". We installed Realtek Driver from the mobo CD — No go. Got an onboard audio. Mobo is ECS 671T-M. Help please…
Thank you for all the response! I appreciate it! But we still got the same problem after installing the driver from the Realtek website. If this might help, here are the things under "Sound,Video and Game Controllers" in our Device Manager:
– Audio Codecs
– Audio Codecs
– Legacy Audio Drivers
– Legacy Video Capture Devices
– Media Control Devices
– Realtek High Definition Audio ** (with a yellow excamation mark)
– Unimodem Half-Duplex Audio Device
– Video Codecs

I’m not sure if one of these is causing the problem… Do you think I should uninstall/remove all of them and reinstall Realtek?
