There must be something about your Ram, as every P.C. has to have it :thumbup:

Basically as i suspected, you have an onboard graphics chip, which in laymens terms, is rubbish for running any graphically heavy applications.

To solve this problem you need a Graphics card. This needs to be DirectX 9 friendly, it needs to be pretty powerful aswell, as The Sims2 is pretty demanding if you want to play it on any setting apart from the lowest :thumbup:

I would recommend at least an ATI Radeon 9800 (Pro/XT) depending on your cash flow, but i would not recommend you getting a 5 Series Nvidia card as these are not great
If you can afford to buy a 6 series Nvidia or a X800XT from ATI then go for that. :thumbup:

You will need to have DirectX installed after the card is put in you rig, and you will need the latest drivers for the card (which you will not get from the C.D. as they will be vastly out of date.)

I hope this clears your problem up :thumbup:
