Thanks for the replies, still having no luck finding a solution. NOTE:- cable and fire wire card is tested OK. I managed to delete my early restore points. Freezes in RX mode, no stray RF issues. DAVE:- I ran a program called Memtest and all tests passed 100% Les:- Freezing occurs with VAC either on or off I have run all the Windows tests and every thing passes Tried to install "Hotfix Fix319514" and it says it is not for my computer. ERNEST: - I checked and found I have an Interrupt request (IRQ) conflict.
IRQ 16 - 1304 OHCI Compliant Host Controller (Legacy) IRQ 16 - Intel(R) 6 Series/C200 Series Chipset Family PCI Express Root Port 1 - 1C10 IRQ 16 - Xeon E3-1200/2nd Generation Intel(R) Core(TM) Processor Family PCI Express Root Port - 0101 I don't believe I can change the IRQ in Windows 7 as they are automatically generated? *I just disconnected from my network and also disabled my network card and PowerSDR still freezes with the same symptoms?* ......................................................................................................................................................................................................
