    I entered the settings and i can't seem to find it, I tried pressing four different keys because the key's you mentioned were not in any of the options to enter various menu's at the boot screen. In the BIOS screen i couldnt see anything that had "Hyperthreading" or "Hypertransport". Perhaps I have overlooked it but i did spend some time looking at all the options.
    That's odd... but relatively harmless. The others are giving you good advice... I'll let you carry on with them.

    ok update the driver for the computer type, it'll only have the same driver selectable but it should still redetect the system hardware state on the next boot.

    ha, believe me, you aren't even in the same league as the people i find annoying xD

    i wonder if vista boot pro or something similar would list the options currently used at startup. its possible windows is still setting it to 1 core at startup.

    Yeah i think it is, because in MSConfig under advanced boot options i could set it to two and ever since it stopped detecting now it stays at one.

    You've already been in the BIOS so this probably isnt it but some BOISes allow you to select to run only one CPU (regardless of the number installed) for extreme compatibility purposes... Sort of like how some HDs allow you to jumper them for 1 gig regardless of their actual size so they can still be used with DOS...

    I'm really starting to worry now, this PC Cost £550 and I've had it for two months and broke it already. It's my own fault really... not everything on the internet is always right so i shouldn't have followed it. Perhaps if it is not too much trouble sombody could try and help me via remote assistance is possible?

    Just to follow up, i realised there is another way to correct this problem.

    since the device manager was displaying the correct amount of cores, it was simply that the system environment had set itself to only see 1 core, you can change the NUMBER_OF_PROCESSORS system environment variable in Advanced System Settings to correct this.
