The only way to change them, especially in laptops, is to go into the Bios and look for an entry called "Runnning PnP OS". If this is yes (or enabled) then the firmware of the laptop does not assign the IRQs but leaves it up to Windows or Vista to do so. It can prodice entirely different results. Unless the other devices are system devices or graphic ports, you can try disabling them in the Device Manager and see if it helps you.
The other thing to try is setting the processing priority to above averate (if you set it to real time yur system definitely will not work well), which would give PowerSDR more CPU cycles than the rest!
