FLex 3000 Crashes now that I dedicated a faster PC to it :(

I replaced a Dell HP6930P Laptop
duo core intel 2.6ghz
4gig ram
onboard ATI graphics.
StarTech PCExpress1394 card
160g HDD-
running win7at first then 10Pro
AVGFree

With
Intel i5 3.2ghz
8g ram
Intel HD Graphics 4460
SIIG DP Firewire 2-Port PCI-e
1tb hdd
Windows 10 Home

On the laptop the PowerSDR never  flinched even running around 80% cpu. I bought the desktop solely for Flex operation. It will ramble along at 4% cpu use but will suddenly jump to an incredible DPC number of 14,735 us. It normally runs about 119us.
I have toroids on all cables, am using the gold FLex supplied cable and have shut down all networking to test with no difference. I have swapped the firewire card to a new slot, there are no IRQ conflicts,power supply is logged and steady and all devices except the PC tower are grounded.
Any and all help would be appreciated - I'm fairly new to 'Flexology'
cheers

My biggest latency culprits are:
ndis.sys and dxkrnl.sys. Can't stop them ore Windows won't run....
