I had a problem with the Firewire card with a via chipset card and it worked fine until a month ago.
I reinstalled Windows 11 Home by wiping the old install.
I reinstalled PowerSDR as recommended before by Darrin
" Downloaded the Full and Incremental installers from my website.
Set "Compatibility" of the Full installer to "Window 7"
Installed Full Installer (which also installs the FireWire drivers for PowerSDR). Reboot.
Installed Incremental install.
Set the Compatibility of the PowerSDR (Desktop icon) to "Windows 7" and "run as Admin" (so I can use it to sync the PC clock)
Ran in DEMO mode first (so FireWire is ignored) just to make sure everything was OK
Then powered up The Flex-5000 and launched PowerSDR.
Made a bunch of adjustments to the settings.
Set the Primary Sample Rate to 192khz (because the default is 96khz because some FireWire cards have trouble with 192khz)"
I also followed the how-to https://ke9ns.com/flexpage.html#firewire I did everything
I purchased another card and it did the same, but I didn't realize it was the same chipset. so it BSOD also only with the power off button.
Went back to Amazon yesterday and bought a Syba SY-PEX30016 3 Port IEEE 1394 Firewire with a TI XIO2213B Chipset and installed the legacy Driver.
I hit Aply or ok in Device Manager BSOD. Hit off BSOD. Hit Save Profile BSOD. Try to increase PFN Crash Dely and try to save BSOD.
Running 308 of PowerSDR.
Anyone Have this card and have it running ok?
How did you fix your BSOD?
