I just got a new, pre-assembled computer from Arsenal PC. I ordered the 2.8GhZ P4 CPU, and, after a bit of graphics card trouble, I got it up and running. Whenever I boot the machine, it says it's a 1.8GhZ processor. It recognizes it as 1.8 all the way, and when it's doen booting, the system properties show it as a 2.4GhZ, but it says it's running at 1.79GhZ right below it. What should I do? Thanks!
