Hello!

I have an old machine, and I want to use for that to learn employees how to use Ubuntu, and to be easyer to switch from Windows. I've been installed 10.04, and updated, but this strange stuff is happend. Graphical installion failed, same strange thing. With alternate workd.

Sometimes, when I boot up, a boot message displayed: Keyboard failure..., often diplayed after reboot, and after shutdown, when I haven't plugged off from AC. I replaced the keyboard yet, same failure... If I powered off, and plugged off from AC, no keyboard problems displayed in boot time.

Details

Configuration: Dell OptiPlex GX60 - in original cover, no changes.

• 256 MB DDR 166 MHz
• Intel® Celeron® Processor 2.40 GHz
• Dell 0C3207 Base Board

I know, that is not enough, but I have three other Nec compuers, with nearly similar config, and they works well with 9.10, 10.04, 10.10.

Live CDs

I've been tried with 10.04 and 10.10, but the problem is displayed too. With 9.10 no strange things displayed, but it froze, during a simple apt-get install.

Syslog

An error loop is logged here, but I paste the whole startup and error lines. The flashing lines are displayed sometimes immediately after login, but sometimes after 10 minutes, but once occured, that nothing happend.

Strange thing is displayed immediately after login: here.

An other boot, after some minutes, strange lines, and loop in log appeard: here.

The loop should be that:

When I hit the On/Off button, the system shuts down normally.

May be it a hardware problem, but I don't know...

Can you say something useful to solve my problem?
