why wont it run

my pc is really old but i actually dont mind not being able to run games in high graphical settings but i just found one of my old games (oblivion) and installed it but when i play the game crashes my computerand it restarts and its weird since i can rune fallout 3 in bearable settings but when i rune oblivion wich is alot older than fallout my comp chrashes my specs are:

OS:XP home edition

1,5g ram

ATI READEON x1650 pro my

CPU = Pentium(R) 4 CPU 3.0 Ghz

nothing special i know since i just use my comp to play lan games with my friends cod4 left4dead etc. but im asking why does my computer crash when i play oblivion even when i pass for the recommended settings on systemrequirementslab but i can run fallout 3 with no problems (i already opened up my computer and cleaned the dust out)

Try uninstalling the game and reinstalling itgmaster456

Should check to see if all your fans are working and you can use this to check your temps.

I saw there were other stuff to check temps but can't remember em. xD
