about that...
As is usually the case with systems that use integrated graphics, the ATI Radeon HD 4250 in the DX4320-02e is not very gamer-friendly, as evidenced by the system's score of 2,612 on the 3DMark Vantage test. You'll probably be able to play older DirectX 9 titles like Company of Heroes but you'll have to keep the detail settings to a minimum. More demanding DX10 games such a Far Cry 2 will likely be agonizingly slow.
Thats from the blurb on that computer....ya you actually need a Video card.
EDIT:....also try a "Clean boot" with windows....this is a massive Page file.....to much running in the background can grind you to a hault.

Has to be a typo...4809 would be over 4 GB and still on the large side.
