[idata]

No Solutions at all!

I set up an new System!

Thanks for your help!

hello together.

once i upgrade my Computer with a Pentium Dual Core E2200 CPU,

windows xp recognized after the first start the cpu and installs drivers.In Device manger it looks fine, 2 CPUs, CPU 0 and CPU 1.

But i am surprised that i can only see 1 ProcessorKernel in Taskmanager instead of 2!

I make a test with a linux live CD and i do another clean win>Xp installation on the same system.In Booth cases all works fine!!!

is there a known of a solution to solve this problem???

Iam shure You will understand that im more like to work on my old windows installation.

I would recommend running the Intel® Processor Identification Utility to properly recognized the processor. If this tool shows both cores, then it something wrong with the operating system.

You must reinstall ACPI driver(In device manager go to "Computer"). You need to change it to multiprocessor ACPI(But after that yor XP can be broken). Sorry for my english.
