You should install
Java 6 (you still have Java 5).
Also upgrade your graphics card drivers. Use the ones from your computer/mainboard vendors' website. Alternatively, the chip vendors' drivers for this chipset are available at
s3graphics.com and
may work for you, too. To determine which chipset you have exactly, use
CPU-Z.
You seem to have a VIA S3G UniChrome IGP onboard graphics adapter. Those are known to cause issues with games on Windows. It might be worth spending some bucks on a dedicated graphics card if related issues remain.
