Ubuntu 9.10 craches using any package, processor wants to die

Binary package hint: ubuntuone-client

I am using an Acer trvellmate 6000 (1.66GHZ, 1.2GB RAM), a continental one. I arrived 2 months ago to the UK, so I plug it with an adapter. Roughly a week ago, mainly while I try to open a webpage with graphical content (news mainly), the led of the processor and noises are informing me the machine wants to die, in a lucky case it leads to a Force quit, in an unlucky one a reboot. This is a pretty amateur description, please tell me what else to write here to facilitate your generous help.
