The symptoms you describe are compatible with an exhausted battery. 
Every motherboard has a small lithium battery to keep the PC clock 
running and also the BIOS settings which are kept in a CMOS memory. That 
battery (usually a CR2032) has the size and shape of a coin and it is 
cheap and easy to change. Around here, they are easily found in hardware 
shops or even supermarkets. They last about 8 or 10 years, so it seems 
that the one in your PC is already flat. I would buy one of those and 
try to revive the ocmputer.
