According to Carrona.org, STOP 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA
Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

Let us check them one by one.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

Run SFC /SCANNOW Command - System File Checker

Uninstall AVG using AVG Remover. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Do some disc checks.

1. Update your SSD's Firmware (Skip it, if it is not a SSD)
2. Re-seat the sata and power.
   
3. Run chkdsk /f/r, following the option two of the tutorial Disk Check
4. Seatool for dos: SeaTools | Seagate download
   Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.

Free up the startup.

1. Click on the Start button
2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
3. Select the “Startup” tab.
4. Deselect all items other than the antivirus.
5. Apply > OK
6. Accept the restart.

Uninstall Magic Disc. Those Disc image mounting programs are often problematic; specially in case when they are set to be auto start with windows.

Let us know the results.

I did what you told me....
In my first report i set CPU to use only 2.4 ghz out of 3.2 ghz because the BSOD was to frequently and i could't use the PC at all.
RAM is ok.
System File Checker :"windows resource protection did not find any integrity violations".
I removed AVG (and magicdisc) and replaced it with Microsoft security essentials and MBAM. Their scan found nothing.
Disk Check : ok, no bads or anything.
Then i enabled Driver Verifier and used PC as usual. Then i set the CPU to use 3.2 ghz (to see what happens), and 5 minutes after the windows' startup a BSOD occured. I guess the CPU is the problem but you know better...
Anyway here's the report after the BSOD Attachment 252369

Disable driver verifier. When a DV enabled crash dump shows a Atop 0x124, DV is no more necessary.

Follow the Guide: Stop 0x124 - what it means and what to try

i noticed that if i deactivate a core the problem disappear. apparently BSOD appears only when the CPU works at its full processing speed....I left the CPU in a service and they told it works fine. I searched for 124 error and it's usualy appears when the system is overclocked but i never overclocked it, in fact i used less then it's power so the pc could work. What should i do?Attachment 252761

Stress test the CPU.
Hardware - Stress Test With Prime95

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

Stress test the Graphics Card using Furmark.
Video Card - Stress Test with Furmark

Check all the other hardware like PCI and PCIe devices, USB devices and PSU.

Finally, The step #9 of Stop 0x124 - what it means and what to try

9) If all else fails, start removing items of hardware one-by-one in the hope that the culprit is something non-essential which can be removed. Obviously, this type of testing is a lot easier if you've got access to equivalent components in order to perform swaps.

Edit: Unistall these programs. If it says to set anything to default at first to uninstall, do it.

Code:

Start Menu\Programs\ASUS
Start Menu\Programs\ASUS\EPU-4 Engine
Start Menu\Programs\ASUS\PC Probe II

Uninstall these programs, too.

Code:

Start Menu\Programs\DAEMON Tools Lite
Start Menu\Programs\MagicDisc

All the disk image mounting programs are problematic, as they virtualize hardware. Among them, Daemon tools is the most frequent BSOD causer.

Try to replace the CPU.
