I just moved two of the three PC's to another room. I hooked everything up on both PC's. When I turned one of the PC's it booted up OK but there was no sound. I looked in the Device Manager and there was no mention of the Sound Blaster sound card and there was no volume in the system tray. I booted into the BIOS to make sure that the onboard sound was still showing disabled and it was. Upon reboot the PC would not boot. There was no signal to the monitor and no hard drive activity. I tried a few more times but the Reset button did not seem to work. I then tried several times to boot a Seagate SeaTools Boot CD. After several Resets I was able to get to SeaTools but the mouse would not work and the PC seemed to be locked up. I tried a few more times with the same results. In desperation I decided to remove the CD and try to boot to Windows and it worked and the Sound Blaster card was showing up now and I have sound. I tried a couple of more reboots and everything seems to be normal. What do you make of this problem? Maybe it is a hint of a soon system failure? Of and on in the past the PC would sometimes frequently lose signal to the monitor. Not sure if this is the PC or Monitor. Thank you.
