10 yo can mean this or that.
so what's the specs - cpu, amount of RAM, GPU, operating system ?
for example with 4GB RAM and a SLIM win7 installation (without unnecessary services running), even after the fans in the notebook gave up I could still play most rpgm games (2dcg), wolf-rpg, html/ textbased just fine.
3D-titles sometimes, depended on being properly optimised, I guess. (some simplistic dungeon-crawlers were too heavy, others worked fine eg. Yumina the Ethereal) )
