Alright, I was using my Macintosh LC when suddenly the monitor's image stretched and it immediately showed a grey screen. I had no choice but to turn on and off again.

When I restarted, there was no startup bong/HD activity and no image. :'(

can somebody help?

BTW: the PSU powered on the Macintosh LC; it didn't click. Also, the the battery isn't too old; maybe several years or so.
