You appear to have several issues. A few suggestions:
When troubleshooting, make sure you disconnect all devices from your computer except for the keyboard & mouse.
"...and the grey notice in several languages appears telling me to restart."
This appears to be a kernal panic.

How did the trip to the doc go? here is my story:
I have had repeated kernel warnings and went to the genius bar at my nearest Apple store and they diagnosed the fault as a logic board failure. My i mac G5 Cost £1500 5 years ago and the estimated cost of repair(£400+) makes it a worthless exercise considering the price of the new i macs. Any advice on what I can do? It is a beautiful computer and it seems a shame to let it end at this.
Any advice will be appreciated.
