9.1 frequent crashes
Hi,
It's a couple days I have the following problem:
while moving the mouse, the pointer stops, and after few secs, I can resume and move it again, unfortunatelly sometimes the pc crashes, and I have to reset.
I have used Norton Disk Doctor, as well as Diskwarrior, and they found some minor, and major problems with the files, and they fixed them.
Indeed by rerunning the 2, they don't find problems.
Any help please.

Thank you.

No, first time I hear it, where do I get it?
Thank you.
Thank you.
I'm going to take a bit of a gamble here and guess you're using a Mac Studio Display with the G4 and that the mouse is plugged into the keybord which in turn is plugged into the monitor
If so, I've had a few instances recently where the machine appears to crash because typing and mouse movement have no effect on the system. But when I look at the underside of the optical mouse, the laser isn't active, meaning there's a fault with the power supply to it somewhere along the line.
So first of all ensure the cables for the mouse and keyboard are intact and not broken in anyway. Secondly, plug the keyboard directly into the back of the Mac rather than via the monitor. If that resolves the problem, then great. If it doesn't this will be interesting...

thank you, and sorry for the late reply.
You are right about the studio display, but the kb is plugged into the g4; the mouse is plugged into the kb, because it is supposed to (cable too short to reach the g4)
And the mouse is not the optical one, it's the old round wheel mouse.
The peculiar fact is it is very random.

Well in that case all I could suggest (at this stage) is to try changing the USB port that the keyboard is plugged into to see if that helps.
Another thing you could do is to change the settings for the menu bar clock (Apple Menu > Control Panels > Date & Time) so that it displays seconds. Next time the machine appears to crash (i.e. mouse and keyboard are unresponsive), see if the seconds are still counting. If they are, you know the machine should be fine and that it's more likely to be the peripherals that aren't working.
Have you tried swapping the keyboard and mouse? If you're still getting the same problem after all these things then we know they're not at fault and that it's more than likely software. What I would then need is a list of your Control Panels and Extensions so I could try and pick something out that might be causing it. I'll let you know how to do this if we get to that stage.

I did what you suggested about the time setting, and indeed the secs kept going.
Now, do you think it's the usb port on the keyboard, or the mouse?
In the wait for your answer, I will change the port on the keyboard (from right one to left one).

Sorry it took me so long to get back, I haven't been using the mac often lately.
I plugged the mouse on the left usb, and so far haven't experienced the crash, but like said haven't been using it that much.
And I still notice momentarily hangs, of 2-3 seconds.
I just tried to get to the extension manager, and following error occured:
error 48, problems with the extensions preferences, try to trash the preferences file.
When clicked to close it:
Error type 10 > rebbot
Click on rebbot, nothing happened, after few clicks, mouse disappeared, I pressed the reset button.

Do you have an OS9 install CD? Extension Manager crashing isn't a good thing, generally, and indicates a reinstall of the operating system would be an appropriate course of action at this stage.
Saying that, if it's a simple problem such as a currupt preference file, a reinstall won't necessarily fix it as it keeps the old preferences.
Have you deleted the Extension Manager prefs as suggested? You can also open it by holding the space bar during startup.

Sorry for the delay.
I wasn't using it for a while, then took some time to test the mouse swap.
Since the change no more crashes.
Thank you
