I have an old HP Pavilion s7000. It has a Celeron CPU and I think has 1GB of RAM. Since I don't know anything about upgrading I was wondering if you could help me figure out if any better equipment such as a new CPU, more RAM or anything like that would fit into it. I don't know if the power supply will be enough to power this or if the motherboard can support any upgrades. I can't seem to find any proper specs for my model of computer which is why I am asking here to see if anyone knows if I can upgrade it to be usable again.
