SAMP freezes FOR exactly 1 MINUTE! (Grand Theft Auto: San Andreas)

Hi all, I have a huge problem.
When you open dialog boxes, for example to write a command /report, or put taxi fare in the sump, my SAMP freezes for exactly 1 minute.
This is a cry for help, I really need this fixed.
I did 5 different assemblies, drivers,cleaning, nothing helps.
I hope that someone here can help me.
Thanks in advance
