Asus P5K Q6600 XP Pro 32 Bit

[Tassie$Devil]

Hi

Friend has 32 bit XP Pro on a P5K MOBO with 3GB ram (DDR667). He complained
of slowness in his system. Ran Task Manager and only a single core was
visible. Ran CPU-Z and it reports back 4 cores. How do I tell if the OS is
correctly seeing all of the cores? Some posts on similar issues on the www
but nothing definitive. I would prefer not to reload OS.

Thanks

Drew

Go to Device Manager and check the properties of the "Computer"
entry. The thing there is called the HAL or Hardware Abstraction Layer.

For example, I have a Core2 Duo and my "Computer" entry says

ACPI Multiprocessor PC

The "Multiprocessor" part is what makes all the cores get detected.
If yours says "ACPI Uniprocessor" instead, that is relatively
easy to fix. You can do a driver update, to switch to the
multiprocessor thing.

Please report back what yours says first, for more info. Some
other HAL options are much harder to repair.

The other possibility, is the issue isn't with the HAL at all.
It could be, that the Task Manager "View:CPU History" setting
needs to be changed, to get a graph per core. Attempts to
"Set Affinity" for a process in the Processes pane, should
also be showing four tick boxes for the four cores (right click
a process, to Set Affinity). If you see four tick boxes, then
all four cores have reported in.

From what I've read, if you change the cpu after os install, ie update to a
multiple core, sometimes you might get by just fine, usually you have to do a
repair install, to see the other cores. try this first.
go to my computer and select properties, see if the proper cores are listed.
a slowdown can also be malware/spyware issues, and other nasties.
