AHHH Powermac G4 wont startup PLease HELP???
Hey guys bit of a panic:
I was doing my normal stuff(browsing these forums and ebay) on my Powermac G4 when suddenly i got one of those evil OSX Tiger please restart screens popup in the middle of my screen telling me to restart my computer by hitting the reste button or holding the power button for 6 seconds......I proceeded to do this and myu powermac now wont boot properly!!!
So now my powermac switches on but doesnt show anything on the screen my monitor remains black. I have tried re-seating the graphicscard and RAM but neither have done the trick.
I would be very grateful for some help and if anyone would know what the cause of a problem like this could be i would like to know.
Thanks in advance,

try zappping the pram hold down apple key+control+p+r at the same time then press start-up let it chime 3 times and let go
also hold apple+control+o+f and start up when in open firmware type reset nv-ram
hope the work or look for the location of the pmu and do a reset go to apples website for more info
failing that try swapping ram testing it etc
try the basic things if no joy looks like a hardware problem

i've experienced something like this a while back too.
try resetting the PMU, instructions here
if not, replace the battery.
if common sense were common, everyone would have it.
