Battlefield 2 causes stop error when I try and run a map, Need some help please! Options?

If anyone can help me fix this, I will be eternally grateful to them. I just dont understand what is happening. Recently, whenever I try to load a map, the loading bar manages to get a bit of the way along (it can vary how far it gets) and then the computer powers off without warning and restarts (stop error). This applies to all mods as well. When computer restarts I get this error reportBattlefield 2 causes stop error when I try and run a map, Need some help please! Options?
Could Be Either

RAM How much ram do you have I would get more the 512 MB to be able to play BF2



It could also be your Video Card. Go to the ATI or Nvidia website and get it updated. Also can your video card handle it.
