I have a daft question. I have a Dell inspiron 9200 with a 1.6 gig CPU, unfortunately it runs at 598 MHZ core speed. Go figure, it just happened one day. Updated the bios which reports 1.6 gig, re-installed XP and still runs at that speed.
So to my daft question. I have a Dell 8500 with a Intel Pentium 4 Mobile CPU 2.20 GHz.
