My computer is the HP Pavilion Slimline, i have no idea what else it is, and while on a game i have been having some problems with text appearing as "$902372 no range" i have narrowed it down to only the updates which have altered text and while on a game, someone commented i need to upgrade my graphics card or something, after this, i frantically searched the web, and it just frustrated me more, if it will help, the game is Dawn of War 2.
The issue could be the system itself. Those HP Slimlines are not gaming systems period. I used to call them laptop clones, and never could call them a desktop. They all use integrated graphics, which are fine for the web and running Office. You can get some graphics cards that will work inside them, but overall, better off building a gaming system.
