The rig is on the  1st floor and with 50 feet of RG58U coax feedline to my G5RV dipole Antenna (40-20-15M) with < 3:1 SWR.   The freezing problem started about a month ago...

So thinking that the RF was getting into the Laptop, I purchased 10 Snap-on Ferrite Cores and put onto Firewire cable, mouse USB cable, Laptop AC adapter DC power in cable, Flex5000A DC power + & - leads from Power supply...  but did not solve freezing problem when transmitting.

FYI, the Firewire Express card is the dual 9 pin 800Mhz  type with a 9 ft. cable, 6 pin on one end to the Flex5000A Firewire input port and the other end is 9 pin to the Firewire Card. 

What do you think is causing the problem?   Any help greatly appreciated!

Windows 7 - check to see if the 1394 bus driver is set to a legacy version of the driver.  If not try the legacy version  http://kc.flexradio.com/KnowledgebaseArticle50433.aspx
