I just build a brand new computer with an Intel Core 2 Duo 6300, Asus P5N-E SLI Board and Windows will not recognize my dual core cpu. CPU-Z only reports 1 cpu and coretemp only shows 1 cpu temp. I do not know what to do.. Ive tried reinstalling windows xp pro w/sp2 twice now and it will not fix the problem. As far as i know i have the latest bios according to the website.. Anyone know how to solve this?
Cant get windows to reconize my dual core???

First, I'd check the BIOS as suggested above. Then, see if Device Manager shows two processors under the Processors group.
LOL, he mentioned them in the first post. Since when does the PSU have anything to do with how many processors are seen? :lol:
EDIT: After reading the manual, the only option I saw was for HyperThreading. I'm not sure whether Asus tied that to the second core or not, but it's worth a shot (a long shot). While you're in that section, it shows the processor info. Does it show up as a Core 2 Duo?
The only thing it shows in device manager is "Standard Pc" .... I just checked the BIOS and theres nothing about turning on/off the 2nd core.. Also CPU-Z at the bottom says 1 core 1 thread..?
also, i dont see anything about processors in device manager..?

Was the HyperThreading option enabled? If so, the only other thing I can think of is to ensure your BIOS is updated to the latest.
EDIT: I just checked my Dell Dimension 4700 and it shows processors in Dev Mgr as well. Are you sure this is XP Pro? Mine are both XP Pro, and I don't have an XP Home machine to look at.
EDIT 2: After looking here it appears XP Home does not support multiple CPUs (and I am assuming multiple cores since they appear as multiple CPUs). Additionally, that would explain why there is no processors group, as you'll only have one supported anyway.

I found this on AMD forums talking about same thing... It may help if someone who knows a little more can verify that it has potential

" It's possible to update the configuration without reinstall all in XP and 2000.
Right click on "standard PC", select update driver and select "Install from a list of specific location (Advanced)".
After select "Don't search. I will choose the driver to install." and then "ACPI Mulprocessor PC".
Here, perhaps, you must deselect "show compatible hardware".
After that, windows must restart and rediscovery the modifications.
Perhaps, windows will ask some drivers after reboot. "

To clarify on wondering if you show two processors. Just right click on my computer and look at your computer info. It should indicate two of the same processing speeds going.
As far as your problem not seeing the processors, call intell not microsoft to solve the problem. And if all else fails call asus for any help. As for your motherboard, is it the Deluxe or SE edition?

Did you reinstall from scratch or just do a repair?
I had this problem once and it was definatly due to windows not loading the HAL correctly.
I used this method to correct it http://www.nforcershq.com/forum/1-vt12269.html?postdays=0&postorder=asc&&start=0
You might want to wait till some more experienced people have looked at this link and given thier advice, They may know an easier way I know this worked for me though.
That was on an AMD X2 for me however.

not sure if you checked here yet, but under Task manager with the Performance tab selected you say you only see one graph for CPU Usage History? if so what is selected under View -> CPU History? (do you have One graph per CPU selected?)
Anybody know if windows users rights would affect this? As in if he is not logged in with admin rights would he be seeing things like not being able to update a driver?
