I built this PC myself about 18 months ago (hence the most likely reason for the problem mentioned below)
Anyway, all the system info shows 2 CPUs and some applications like Photoshop show that this machine has got 2 processors, when it just has one.
How do I configure the machine to correct this? I am concerned that perhaps it might be affecting performance.
BIOS or OS?
FYI, ASUS P4C800-E Deluxe Motherboard. P4 2.8 Prescott CPU.
