Weird Monitor Problem Options

[gavinf]

Hi

Can someone help?!?!? Please?!? I have this annoying thing where I switched monitors a while ago, and found when I booted my G4 into 9.2 with the new monitor the startup got about 10% through the bar (before any extension icons) and then flickered twice, then the bar moved a little more, and the screen goes black. Sometimes it won't reboot from the switch from there. Tried another monitor (original monitor gone). No change.

Funny thing is, it boots fine into 10.2 and in Classic, and it boots fine from a CD.

Tried base set of extensions. No change.

I tried an in-place reinstall of 9.1 (couldn't find the 9.2 disk). No change. Reinstalled 10 over that. No change. It's driving me completey bonkers.

Is your 9 a 9.2.2?
what is your monitor?
Which video card are you using?

anyway seem you may have a video card driver or extension problem (save the baghun hints thank you).

first thing to do (to secure thing a bit):
- verify your cables AND the video card on its port are secure (unplug then replug) (do the same for all ram and drives, in case, go on quietly it's not a trucker job)
- zap the PRAM (apple-shift-P-R on start up, let the keys down until you hear the mac sartup sound 3 times then let go, before that it must not startup as usual!
- re-initialise the motherboard: open the mac, find the lithium battery, near it one or two tiny buttons, press them a few seconds on start up then let go, don't touch anything else.
- then if no changes reinstall the card drivers (or the entire 9.2.2 system which would be safe)
