This is a US model and you can get support here:-

Sadly, the graphics are not upgradable on this model as the Intel graphics are part of the soldered in chipset.
As this model is approaching 10 years old, there is very little ongoing support from Sony. All you can do is to max out the RAM to 8GB and look on the Intel website for the latest driver. The website should also give you the limitations of the graphics - particularly for gaming. A SSD would also help but your Vaio will always be limited by a the Intel Graphics which were designed for general use at a budget price.
On reflection the VPCL216FX would have been a better purchase with its i7 processor and nVIDIA graphics but this was more expensive to buy.
In its day this was a fantastic all-in-one computer and is still good today as long as you don’t need high graphics power.
