Co mám dělat když mi deska dorazila s něčím co vypada jak lehce poskozene piny. Vím že reklamace je možnost ale zaroven mam strach ze mi jen reknete ze to je moje chyba a konec?

Dobrý deň, bude prosím v druhom PCIe slote na tejto doske fungovať po pripojení SoundBlaster v prevedení PCIe1x? ďakujem Peter
