Mach3 causing computer to restart.

[bofee]

I'm just getting started with Mach3 on a CNC router build. I had basic functions working a couple of days ago with the Gecko G540 configuration installed. Today everytime I load Mach3 my computer reboots. I disconnected everything and reloaded the software, no help.
Anybody have suggestions?
Thanks

What are the specs of the computer?
Check in the BIOS to see what temp and voltages are like.

The computer is a 3Ghz Pentium 4, CPU is running at 25 Deg C. The hard drive is about 10% full and checks out clean for errors. Upon restart I'm getting a message,"System has recovered from a serious error."  I can't even run the driver test app because the computer reboots when Mach3 takes over.

Did you see what the voltages in the BIOS were like? Could be the power supply is failing or even the voltage regulation on the motherboard itself. Other things that may cause it could be a conflict between software such as maybe an anti virus, try disabling anything such as that and see if it helps.

Have you tried all the Mach 3 optimization steps if you're running XP?

I will look at all the above. There is also a section in the manual (2.4 Installation Problems) that describes what I am seeing.

we have had this exact same problem,   it was the processor overheating.  ( after checking everything else ). 

when your computer restarts, does it always reboot or does it sometimes have trouble rebooting

[bofee]

Nope, no apparent problems on reboot.

I would  not rely entery on the temp settings from your bios.    There are very few things that shut a pc cpmpleatly down,

You have checked your chip for overheating.
Run a disk check, select the option that says look for bad sectors, ( it will ask you to shut down to run it )
Run a memopry test.

If your chips not overheating, will propbebly be your disk.   

somtimes in the bios, it stors the last fault condition,   ? make sure xp is updated as i think there is a upgrade for the chip driver if its a duel core chip

I ended up re-installing Windows and Mach3 is running OK. I may never know the details of what was causing the computer to re-boot.
Thanks for everybody's help.
