Power Mac G4 Wont Display on screen

[Nerka]

Hey,

my computer is a powermac g4 dual 1.25. Running 10.4.10 on it. I came home from a friends house to see my computer all jacked up. Now my computer wont even start up the regular way. I hear the chime once and the fans. But it wont get past that point no matter what i've tried. I've reset the pmu button but after that i'm a bit stuck.

oh and the mouse and keyboard don't work when attached to the monitor ( apple 17 inch monitor ) but the mouse does light up when plugged in behind.

anyones helps or suggestions would be most appreciated. Thank you in advance

i think your monitor is not plugged in/turned on

If the mouse lights up might be a video card or monitor problem.

Had a similar bug with my G4 Quicksilver, had to re-seat the Graphics Card in order for it to work. (System would boot but no picture.)
