I have a Leadtek Winfast A280 card and I recently downloaded an older driver (nVidia 1.08) & installed it.

Now when I try to capture with Ulead VS quite often it crashes with the BSOD alert "DRIVER_IRQL_NOT_LESS_OR_EQUAL" and mentions "nv4_mini.sys" (which is the nVidia driver).

Sometimes it will capture, but more often than not it will crash & I have to turn off the power to shut down. When I reboot, the black "system info" screen at the start is garbled, but it still reboots & seems OK.

Any suggestions what I can do? Do I need to uninstall then reinstall the driver? Or Ulead? How do I know it's installing in the right "IRQL" or memory cluster whatever? (sorry I'm bluffing with the terminology here, ha!)...

Thanks.
