Those are not a proper list of specs for the purpose. Among other items not included, you left off the most important part of all for a gaming PC. Compare what you wrote to the amended requirements and you'll see what to add.

P. S. (Added in edit) I answered at 7:26 AM, CST, and may have missed one possible conclusion. The game does require the REAL existence of an actual video card, one made by either AMD (ATI) or nVIDIA, one designed for running games. Such a card does not steal any main memory for its use.
However, instead of 1024 MBs of main memory, your PC has a very odd amount, as though you have some awful old Intel chipset video chip that needs 64 MBs for itself, and then a couple of MBs extra get used up somewhere else. You will need to buy and install a real graphics card, if you have a desktop PC there (I am not going to waste my own time looking up that one on HP's site).
