512 mb ram = lolyou'll need to fix that
I REALLY hate when you post ANYTHING related to hardware, in particularly RAM, you have ALWAYS been wrong in almost ANY topic you posted in about RAM.It is the minimum he can have, therefore it will work.
512mb might be okay for Windows XP, but any amount of ram under 1GB is grossly out of date. Maybe in 2008 you could have stretched it, but its just too old hat now.

So the graphics card would be the problem?
But I'm using Windows XP.
No.You need at least 2 gb of RAM or your game will crash whenever it overloads your page file.
I have 1.5GB of RAM and play TF2 with no issues what so ever.
Ram isn't even expensive. Why would you only have 1.5?
Ram is expensive with an outdated computer, go see what 1GB of DDR RAM sells for, and then take into account I have no job.
