We have an office with computers that are networked. Sometime last Thursday, one PC that has our tape backup system in it was running and either had a power glitch or the power flickered while the tape was backing up our files. The next morning the tape was stuck, but we were able to finally get it removed. Shortly after that, the video card stopped working. We installed another card, then discovered the other video card did work in another PC.
After all of that, the keyboard stopped working after a reboot. We have plugged all kinds of keyboards into it and cannot get one to work. I even tried a USB keyboard and it didn't work either. Because we have to use the crtl+alt+del to log onto the network and finish booting the PC, we cannot do any updates or repairs to resolve the problem.
We are suspecting there is something wrong with the motherboard or something was reset in BIOS during the reboot. Anyone ever come across this or know how to fix this problem?
