Everytime I open my pc after some hours off, I get bluescreens when I log in, around 2-3 each time and then system works fine. I used to have the problem before, updated all my drivers and problem got fixed for a while, but now it's back again and no more drivers for updating are available.

The errors I get are:
SYSTEM_SERVICE_EXCEPTION
DRIVER_IRQL_NOT_LESS_OR_EQUAL
MEMORY_MANAGEMENT

And usually the problems are from:
ntoskrnl.exe
ntkrnlmp.exe

I have used memtest for hours and no problem found, changed graphics card from ASUS to nVidia and still problem occures... I'm also using the driver verifier in these dmps I post. I also include the results from jcgriff2 BSOD File Collection app and perfmon.

Honestly, before you do anything, I recommend a quick Prime95. Make sure your computer isn't 5 sometimes when it adds 2 and 2. BSoDs are very frequently caused by bad hardware.

Prime95 showed no errors and system restore did not much on the problem... Any ideas what's wrong from dmp files?
Also the only new hardware I installed was the graphics card, after the problem appeared.

I pulled up your manual for motherboard and soundcard.

Somethings to try

1.Take out your Asus Xonar DG sound card and see what happens?
2. Reseat you Sound Card and move to different PCI slot.
3. In the Bios did you disable onboard sound
4. Do you have your front computer case plugged into sound card or where do you have those plugged into if
you are using it?(Audio headphones)
5. Make sure cables are plugged into soundcard correctly if you did.

1. In Bios make sure PCIe is used for Primary Graphic Adapter
2. Onboard Audio Controller-Disable or Enable
3. Have you Overclocked your system ?
4. Load Optimized Defaults :Rest BIOS to The option on the main menu allows users to restore all of the BIOS settings to the
default Optimized values.The Optimized Defaults are the default values set by the
mainboard manufacturer specifically for optimal performance of the mainboard.

1. You said "changed graphics card from ASUS (ATI/AMD) to nVidia" or
Nvidia to Nvidia?
2. Did you do clean uninstall of ASUS drivers? (Control Panel)
3. When installing Nvidia card did you choose "clean install" when asked for installing new drivers?
4. If nothing works then might work...
