I have a Dell Dimention 8400. 3.2GB, Pent 4, with Hyperthreading. The Performance Test baseline information indicates "Unable to detect" hyperthreading. I checked the BIOS and the hyperthreading is on. The CPU test are quite low when compared to other computers with the same processor, memory, and windows XP. Also, my PC usage never goes above 52%. I even ran the PC usage durring the processor test and it still does not go above 52%. Does anyone have any ideas?
