Thank you all, the problem is solved and was trivial. In computer shop
installed me processor P4 without HT.
After installing the correct one, with HT all work perfectly.

I must changed standard kernel from distribution K12LTSP 4.2 to kernel with
smp included.
It was done by the valuable advice of Dan Yong:
   #    yum install kernel-smp system-config-boot
the instalation runs without problem via ADSL internet line.
After instalation the new part menu appears in System settings->System
loader. There
it is needed to change the pointer for Fedora Core (2.6.10-1.741_FC3smp)
/number of version may variable/
Then restart computer.
All should work O.K. Do not forget enable Hyperthreading in BIOS!
