BSOD 0x00000050

Hello

Recently I had problems with BSOD 0x0000003b. After updating Windows it disappeared. I overclocked my CPU to 4.5GHz and replaced my Radeon HD6970 to GTX 780 TI. Today while browsing internet new BSOD 0x00000050 popped out.

My PC:

Motherboard: Asus P8P67 rev 3.0
CPU: i5-2500K
GPU: GTX 780 TI
Memory: GoodRam 2x 4GB CL9 1333MHz
Hard Drives: Kingston SV300S37A 120GB | WD Green WD10EZRX 1TB
PSU: Fractal Design Newton R3 600W 80+ Platinum

Could you guys help me solve this problem?

Welcome to SevenForums,

Firstly please update to service pack one as this can remove a lot of bugs:

Code:

Wersja systemu operacyjnego:         6.1.7600 BRAK Kompilacja 7600

Back to your BSOD:

Code:

BugCheck 50, {fffff901c05d6e74, 0, fffff9600007cca3, 5}


Could not read faulting driver name
Probably caused by : win32k.sys ( win32k!bLoadFontFile+1f3 )

Followup: MachineOwner
---------

Code:

PAGE_FAULT_IN_NONPAGED_AREA (50)

   Tip

Win32k.sys - page_fault_in_nonpaged_area -

A stop message that occurs when the demanded data is not found in memory. The system produces a fault, which usually specifies that the system looks for data in the paging file. The system cannot locate the data and recover it.

why?

An Antivirus program, damaged hardware, a buggy system service and a ruined NTFS volume can all generate this type of error message.

New Hardware?

If the BSOD is after the installation of new hardware, In order to fix this issue, remove the hardware to see if the error reappears, if the hardware has been added to the system newly. If the existing hardware is at fault, remove or change the faulty component and run the hardware diagnostics.

   Warning

Please make sure all of your drivers are up to date before continuing!

Drivers - Find and Update Outdated Drivers

Scan the system for possible virus infection with the following programs.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

I notice you have AVG installed this is known for causing BSOD issues when using Windows 7:

   Information

AVG Anti-virus is known for causing Blue screen of death issues on Windows 7.

I recommend you change your Anti-Virus and see if the problem still persists.

Here is a list of trusted Anti-Virus's:

AVAST 2014 | Download Free Antivirus Software for Virus Protection

Avira Free Antivirus - Download the best free antivirus software

Free Antivirus Software - Download Bitdefender UK Free Edition

Brilliant,

I have had a look for you, and there is nothing that stands out as a major cause.

However there are a lot of outdated drivers.

Lets take this one for example:

Code:

Driver Name       : mv91xx.sys
Address           : 00000000`01149000
End Address       : 00000000`011D5000

As we can see its 2010, it may be an idea to update this, but as i mentioned that are alot of these.

Because of the bugcheck we are receiving i am 90% sure its driver related, Here is an example of your bug-check:

   Information

One example would be installing an NVIDIA graphics card in place of an ATI graphics card without changing from an NVIDIA driver to an ATI driver. Or, installing a Canon printer in place of an HP printer without changing drivers.

After you have updated all the outdated drivers, we will see how the problem looks then.

If the problems started after the change, try to change them back?

Ohhh sorry i misunderstood, It may be fixed now i believe it was down to outdated drivers.

But just in case, leave this thread open, and i will be more then happy to help.

Ok, thank you for your help :)

You seem to have removed your dump files but a bugcheck 50 is usually memory or RAM related, have you tested your RAM?

   Information

MemTest86+

Run a minimum of 8 passes, preferably overnight, or until errors occur using MemTest86+.

Use this tutorial to help you use MemTest86+:
RAM - Test with MemTest86+

That "probably caused by" above and the drivers bluescreenview pointed to are false positives, they are core Microsoft drivers and almost never the actual cause.

Yes, I used MemTest86+ to test my memory, but I didn't know that I have to run it so long. It passed 1 test without errors. I will run it over night. Thanks for advice.

edit 2:

After more than 9 hours of testing.



No errors. So I guess my memory is fine.
