yeah, dells can be a pain in the ass when it comes to tuning. "Im stuck at 319 ghz" I think you mean mhz. how much and what type of ram do you have?
How do you get your system specs up? I just want to show mine, but can't remember how.
you click start, and then click run, and then type "dxdiag" the click on the tabs to view the different areas of your system specs
