Can you check the boot options in ms config to see if it has been restricted?


select start -> run (or hold the windows key and press r)


type msconfig and press return


select the boot tab


select advanced options


check the number of CPUs and maximum memory properties

Check what settings you have in the BIOS.

It could be BIOS restricting such use of resources, as normally Quadcore should show multiple logical CPU in the Task Manager.

Check what details you see in the BIOS how much RAM and what is the CPU Type? Also see if any limitations set over there.

What does computer properties reflect.
What graphics card/s do you have? See of hat memory might be allocated/referenced there.
With the CPU it depends on the view options you have.

how is it seen in device manager?
if wrong, it could be an Updated OS that went wrong (eg not updated fully)
and then you need to reinstall in most cases

stick out and stick in the ram bars of your hardware when the pavillion is turned off. Sometimes it is just a missing contact.

Hardware may be 64 bit
But is the vista o/s?

Right click computer then select properties to check version
If it is 64 bit it will say so specifically

I did the msconfig and the options were greyed out. I then checked marked it and selected the proper settings. The OS is 64 bit. When I go back to check to ensure if setting have stayed the processors stayed at 4 but the maximum memory went to 2048. Again I have over 6 gig of Ram. This is at boot though.

The task manager now shows all four processors and a total of 6140 Physical Memory. There seems to be some strange behavior still though. The system when idle is still using 2.6 gb of RAM and the CPU Usage spikes to above 30%. The disk usage keeps poping up. I dont know if this is another whole set of issues. The Memory and CPU number seems to be solved now though. Still cant set it to max at boot for RAM though.

As I asked check what settings you have in BIOS as that could be the one controlling your resources if any tweaks set over there.

it does not use 2.6 Gb ram; it only reserves it, since you have 6 available
