@ zzzttt: I have an ASRock Z97 Extreme 4 motherboard and get the "PCI Data Acuisition and Signal Processing Controller" error in my Device Manager.
I got it on a fresh install of Windows 7 Extreme x64 SP1 US after installing AIDA64 v 4.70.3200.
I make use of Symantec System Recovery images and every time I deploy an image before the AIDA64 install, there is no error.
Every time after I install AIDA64, the error is there.
Any help, or update, would be appreciated.
Thanks.
