Did you check in BIOS to make sure all cores are enabled ?

run msconfig and ensure that under advanced options you have not got the cores box ticked, or set it to 4.

the hal is what sits between windows and the hardware, it sounds to me like your hal has configured itself for a single core processor, you have to reinitialise the hal is i'm right. When did you install windows and when did you upgrade your hardware?

hal? sorry if its a newbie question , installed windowds 7 around a month ago then upgraded my processor a few days ago

what was your previous processor?

and if you look in the link it talks about the hal, look to the device manager entry for the acpi processor

i3 3220, and the hal thing is ACPI x86 -Base PC , little bit baffled about this hal thing, i have to do somthing with it what would it be ?

what does the device manager tell you that you are using, a uniprocessor or a multi processor? look at the dll's listed in the link to tell the difference.
February 10, 2013 1:54:36 PM

ACPI multiprocessor computer = Halmacpi.dll
i have the halmacpi.dll on my pc
but i dosnt say anything about that on my device manager

February 10, 2013 2:12:50 PM

msconfig>Boot>Advanced Options Number of Processors>4>Apply>Restart Now,
