So you added a new video card to replace/upgrade the on board VGA, experienced issues, went back to the original no-issues-onboard VGA , but the issues persist?

Not sure,
I replaced the defect monitor  the same time,
please read my post above!
That´s why I changed the thread title.
Thanks
 
 

if you're not sure what you did it makes it very difficult to troubleshoot (i did read your post, more than once)
 
maybe someone has experienced the same?

Lawp,
thank for trying to help,
I had some detailed questions above, I will post them again now.
OK?
 

Hi gents,
now it´s getting delicious.
The last days I tried several things to increase the source of this not loud,
but disturbing sounds,which are very small and randomly,no real pops:

Deactivated first the onboard videodevice, newstart and .... noises.
Deactivated the Nvidia geforce GT 640 and trying with the onboard videocard... noises.
Deactivated and removed the Geforce gt 6400,newstart, still noises.
So I left the box in this configuration with the onboard videocard,
to shootout the gt 640 as a source for this ,sorry,sh-------.

@Cjay,thanks,
I confused E/A conflict with IRQ sharing, so sure I had to try every PCI Slot for
the La Cie firewirecard ,but still ......noi....
Is it possible that the source of the noises is a wrong setup of irq in the bios?
If yes, which setup can be recommended?

Another question about that:
could the PCI firewire card be the source of that,
cause the modern mainboards use reduced pci-e slots as pci slot ,anybody knows?

@ maxipower,
thanks for your hind,
I use a focusrite saffire pro 40 via output 1 and 2 balanced jack to balanced xlr
input of the Yamaha hs80m..This reminds that
I also got a new monitor at the time I got a videocard, the last modell was defect (benQ hd 2450)but no noises.
The new benq could also be a source for this noise
Both audio-monitors(the yamahas) use the same power source.

Not shure ,but the next step should be to change the settings of the bios ( irq),
if yes, to which settings?
if not, what do you recommend as the next step?

Thanks for every hind,
Pragi

I forgot to mention:
Antivirus ,firewall and network are disabled when mixing/mastering.
The mainboard is an Asus P8 Z77- vlz

a firewire card that is not texas instruments chipset is known as a possible issue

@lawo
Please stop if you can´t answer my questions,.
Thanks a lot.

After  3 days of I managed to get rid of this stupid sh.......,
but really don´t know exactly why.
First, yesterday I found this thread here in the forum:
http://forum.cakewalk.com/Pops-and-crackles-with-a-twist-m2953259-p2.aspx
The tests her  results that the cause of this noises are not based on the videocard,
so I tried this ,made by cake´s alex:
 
Open Sonar, Open a project
Go to Preferences -> Sync and Caching
Take note of play and record buffer size. Double them (or something)
Click OK
Go to Preferences -> Driver Settings.
Click ASIO Panel.
Click OK to close preferences.
Play your project a little.
Close Sonar.
Open Sonar, Open a project.
Go to Preferences -> Sync and Caching
Put ye olde values back into play and record buffer size.
Click OK.
Play project.
Close Sonar.
Stand on one leg. 
But still some noises left.
So had the idea to try another driver for my focusrite saffire pro 40,
the mix control version 2.4 and at least,to stand on one leg.
 
I know it´s hard to help with such issues when the 
cause is not described exactly,but it was not possible for me.
I´m really happy to write this,
my issues are resolved.
