System reboots from mouse movement

System reboots from mouse movement.

The OS is RH 6.1.
Gigabyte mainboard..circa 2001
SIIG Parallel card LPT2
Adaptec AHA-150xx SCSI card
No network card.
Digi-board multiport serial board (8 ports)
PS2 mouse and keyboard.

Sorry I can't bee more specific, but the system is two hours away at a client site.

Within the last few weeks, the system will reboot itself whenever the mouse is moved. Simply / Accidentally moving the mouse while the system is ON results in an automatic reboot...No Questions about are you sure...NADA


Before realizing the mouse had something to do with the reboots, we changed out the power supply and tried different battery backups thinking it was a power issue. Obviously...No Change, still reboots

After finding the mouse had something to do with the reboots, we tested the reliability / repeatability of the problem. It is reproduceable. Move the mouse and the system reboots.

We tried different mice with no suscess. At this point, the client has the mouse sitting behind the monitor, hoping nothing will disturb the mouse.

This system almost never goes to X. The end user turns the system on in the morning. The server is being used as a console/workstation access to the application, as well as allowing 4 other tty sessions into the resident application. All access is text based. The only need at the time for a mouse was the ability to easily configure system resources via Gnome desktop.

The "server" basically is running as an application server on workstation hardware. I seem to remember assisting during the initial install. Everything was loaded but not neccessarily configured. Linux is being used to provide a virtual machine for a PICK D3 database application.

At the end of the day, the enduser logs off our application and shuts down linux using "shutdown -h now" at the command prompt. The same people are still working to the doctors office. No change in personel.

The system has been in service since the summer of 2001. AFAIK nothing appears to have been changed with the system. Our client is a doctors office, meaning the employee's are not techie's. This problem seems to have just poped up.

I am at a loss and need some help trouble shooting and/or a solution. We do have access to the system via a dial-up connection. Tell me what I need to investigate, and we'll do-it.

Smells like a hardware problem to me.
If swapping the mouse with a new mouse showed the same problem, it might be the mouse-plug (or-what-do-ya-call-it) on the mainboard.

This would be hard to debug remotly with dailup :-(

Is it posible for you client to try a USB mouse?

Thanks huibert,

Not having any other explanation, I am leaning towards a mainboard issue.
