Windows 7 Service Pack 1 Audio/CPU problems

Installed bunch of W7 (about 80 or something) updates 2 days ago and Service Pack 1. (Usually DAW isnt hooked up to Web, only about once a year for updates) and started having audio drop out problems.

Yesterday was working on a project and about every 5 minutes or so a 5 second audio drop out occurs and right when it occurs Cubase CPU meters spikes to red for about a second.



my setup:
Windows 7 Ultimate x64
Cubase 6.5.1 x64
Presonus StudioLive 16.4.2 thru TI based FW adapter using Legacy FW driver
 
It's funny you mentioned the web.

Have you treid re-disabling your web access? I know sometimes if you have a wireless connection, it can definitely interface with the audio driver.
 
I don't wanna do complete re-insatll yet (usually it takes up to a week to reinstall all software)

I double checked if all unnecessary Services are disabled according to BlackViper.
No AntiVirus, No Windows Defender, All web/updates etc services disabled.

>> I Also noticed that the drop out happens after I do "Save" in cubase (I do save very often) and aproximately after 16-18 seconds after I click "Save" or "CTRL+S" the drop out occurs.

And When the project gets pretty big with alota patches load in vstis.

LatencyMon gave me "Your System seems to have a problem... One Problem maybe related to Power Management, disable CPU throttling in Control Panel and BIOS"

I Checked Settings in CP the CPU cooling is set to "Active" and in BIOS everything is Disabled except A250 or something, don't really remember, but the CPU BIOS settins are according to DAW recommended settings from Steinberg or Presonus Website


I didn't try Updating CPU or BIOS drivers yet.

edit:
This is a weird, I ran the LatencyMon again, the dropout occurs after doing "Save" but LatencyMon doesn't detect it, says "Your System appears to be suitable for handling real-time..."
Also, the very bottome bar called "Highest reported hard pagefault resolution time" is all the way in the red zone, whole bar full!
 
Ok I updated BIOS. Same Problem

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 4:30:45 (h:mm:ss) on all processors in the system.

Not sure if you answered my question.

Did you try to disable your wireless network? This can sometimes interfere with your audio driver.

That's the first thing I re-disabled after the updates and service pack 1

You may have already mentioned this but have you checked for driver and Cubase updates?

Latest Cubase, Latest Presonus drivers, and all the rest latest except for FW I use "Legacy" Driver

Some Imporvement:
After I uninstalled and Installed latest presonus driver, now there's no drop-outs but just a click/pop now and than, and always click/pop 16-18 seconds after hitting "save" in cubase.

Ok, I re-imaged the C Drive with the disk image created before Installing SP1.

The irritating audio popping/clicking is gone now..
 
If I were you I would set the updates to manual instead of automatic this time. Especially with drivers that are working fine. A bunch of frequent updates usually ends up with something fixed but something else broken after a while.

I have updates (and internet) disabled completely, but about once a year sometimes I update manually, like in this case
