IE 1394 wont recognize devices win 7 64

Hi,I am not sure if I am re posting this but the last one I made never showed up.
I am looking for help with IE 1394 not recognize devices in win 7 64 bit.I have updated the drivers to legacy,the device manager says everything is working properly.I even went out yesterday and bought a new pci 1394 card and it still wont recognize my canon dv cam or my focusrite saffire pro 14 external audio card.I have a clean pc that I checked with all the software recommended by this site. I sure hope someone can help me resolve this issue.
Thanks

Thanks,the sound card worked fine on my system for about two years.I just recently started this,it also used to recognize my cam,the cam is a canon hv20.here is a little more info on my system.Intel quad q9650 processor,8 GB corsair gaming ram,asus striker II motherboard.I just put a brand new inland pro pci 1394 card in two days ago and it still doesn't work.

 

both devices worked fine until about three days ago.the canon HV20 and the saffire pro 14 have worked for almost two years on this system.I even went out and bought a new pci 1394 card,I got a inland pro pci 1394 card.I thought replacing the old one would work but it didn't.here is more info on my system,I have an intel quad Q 9650 3.O ghz processor,8 GB of corsair gaming RAM,a asus striker II motherboard.the motherboard has the latest bios #2402.

 

I am starting to think this may be a win 7 os problem.

 

Thanks for the ideas,I have been using ccleaner for years.I will try what you said though,I ran the registry cleaner part and always keep the cookies cleaned out,but have not taken the cards out then ran it.I will give it a try later or tomorrow.
Thanks again.

 

Well,I gave that a try and Ccleaner didn't pick up any registry for that device.still not working. :cry

 

Everything in device manager is fine with no yellow ! next to them.windows is up to date.I am thinking of just going out and buying a usb audio interface.I have to get my sound up and running asap. :-o
