Triple core CPU showing ONE in task manager

That's a good idea. With 2 OSs already saying the same thing I didn't think it would be worth it. I just got done replacing the PSU and removing the heatsink and applying new thermal paste and cleaning everything. Maybe I could grab my "Jaunty Jackrabbit" live CD and check what Ubuntu says. It would be a REAL mystery then....

I have hope because the BIOS says I have the correct cache. It's so stripped down though.....the BIOS does not even have "PC Health Status" There are almost no options.

I am feeling defeated.

Thanks very much for the idea. I had not thought of that.

I also made the mistake of e-mailing HP just to let them know the CPU had probably failed. I told them I was dual booting. LOL I guess that was the end of any warranty. I didn't have one anyway so I thought I'd see what they said.

Thank you for contacting HP Total Care.

BTW - the CPU is also running 10C cooler after new paste and only one core running....

Im using Vista Home Premium 32bit. After I install it, i realize it was sluggish assuming it was 32bit problem coz I test b4 vista 64bit it was a lot smoother.
Soon realize Vista only detect 1 core out of 3...darn...
I ask my friend and other forums, none have the solution til I read this article that link to 1 CPU detected in dual core system. -Solution - Vista Forums
I try an error out of the method, which i have tried before earlier with the "no. of processors" checked (nothing happen after reboot). After reboot, it was the happiest moment since 3days bother by the Phenom single core problem. Yahoo.... Total of 3 cores back to pumping in against workloads. That was hell a lot smoother than stucked in single core...

The method I used:

http://www.vistax64.com/tutorials/15...rocessors.html

1)
Start>Start Search>msconfig
Boot Tab
Advanced Button
The startup number of processors was set to 1 and could not be changed
Unchecked the number of processors checkbox
Check "Detect HAL box"



Click Apply and Reboot
After reboot the number of detected cores were 3...:)







After success, go back to msconfig>Boot Tab>Advanced Button, check the "No.Of Processors" to 3, uncheck the HAL, apply, OK, Reboot...

Cheers, have a try...At least it work for me...

Okay, this is amazing. After 2 months I did exactly as described above. (thank you) IT WORKED IN VISTA and Windows 7 (from within Vista)

So, I am left with a dual boot machine with Windows 7 also. In Windows 7 the "detect HAL" option is not there. At this point I don't think I had a performance hit from this issue. I have used the machine for editing video and pics for two months. I would like to figure it out though and find out why this happened.

Anybody know how to do the exact same thing in Windows 7 without the "detect HAL'" box?

Edit: This seems to work from within Vista with the "detect HAL" box but after restart it's reverting back. I suspect for the same reason it happened in the first place. If you know what the problem is.....please let me know. I can get it to show 3 cores after 1st reboot next reboot it reverts back. Thanks for any help. This may give someone smart a clue.

I did discover that if I leave the #of cores at 3 after reboot, it will stay. I have not booted into Windows 7 yet to find out there but.......theres still a problem. You should not need to have the # of cores set to all. I have 8 (4 real and 4 virtual) on this CPU and that setting is one on this machine. (i7860)

I don't really care since it's my 3rd best system now but I would still like to know WHY this happened and how to really fix it. I believe it's hardware related. I think the CPU itself is flawed. I would love to hear an argument to the contrary.

Thanks for the help man. It is working fine it seems.
