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

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

    It only says there is one core if its tick or unticked
  5. untick it and then reboot
  6. sorry how many cores does task manager show?
  7. jsut one and i have tryed unticking and rebooting still not working

    theres nothing on that page about processors?
    or anything along that line
  9. 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?
  10. hal? sorry if its a newbie question , installed windowds 7 around a month ago then upgraded my processor a few days ago
  11. 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
  12. 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 ?
  13. 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.
  14. ACPI multiprocessor computer = Halmacpi.dll
    i have the halmacpi.dll on my pc
    but i dosnt say anything about that on my device manager
  15. + if you are going to suggest Detect HAL on msconfig i dont have that option
  16. ohhh i did it,
    msconfig>General>Normal Startup>Apply>Restart Now
    msconfig>Boot>Advanced Options Number of Processors>4>Apply>Restart Now,
    tah daaa , thanks alot for your help though much appreciated
  17. good, all sorted then?
  18. yup all cores ready to go
