I have a weird problem that I can't figure out:
PowerMac 8500/120 w/ Crescendo G3/300 Card
Mac OS 9.1 (9.0.4 did the same)
128 M RAM
If I start with VM off then computer boots just fine but system is very unstable (locks hard in less than 5 minutes).
If I start with VM on then computer hangs for good right after "Welcome to Mac OS .." screen.
I can start with Extensions off but what good is it?!?
I have rebuild desktop 4 times (by hand and with Norton DD 6.0). I have zapped PRAM 8 times (by hand and with TechTool Pro). I have reinstalled OS 9.1 clean. I have ran defrag using Norton SpeedDisk 6.0. I have updated disk driver and ran "Test Disk" command from Disk First Aid. I have ran DiskWarrior and rebuild whatever was messed up. I did the same after a restart using Norton DD 6.0. I have also ran a utility called "Memory Contents Fixer" (found at VersionTracker).
The only option I see is to re-format the drive which is the last thing I want to do.
I am now out of ideas. Does anybody else have any?

Its an extension conflict.
Boot with the MacOS All extension set and see how it goes - if it boots, by process of elimination find the culprit.
If it doesn't, go to MacOS Base and it must be something that the MacOS installs...

That's the first thing I tried. I tried Mac OS All and Mac OS Base. Same story.

1. Run Drive Setup Test if you haven't.
You can continue to work while it tests sectors.
Requires booting from another drive or CD (as do most disk utility tests)
2. Does it happen off another disk?
3. Move preference folder out.
4. What kind of drive? IDE? SCSI?
5. Make sure nothing is in Startup Items
6. Guess you can live w/ VM off if you have RAM, if not, well, 256MB won't even set you back $95.

1. Done that. Didn't help.
2. I am looking for another disk to put in. It is a SCSI drive and I don't have any around.
3. Moved Preferences out and reinstalled OS.
4. SCSI 1.2G
5. Startup Items folder is empty
6. With VM off apps are crashing. I have no idea why. Spending money to get 256M RAM would be a $500 investment (SIMMS costs more than DIMMS). I would rather get an iMac instead.
Thanks for suggestions.
