Windows 7: BSOD playing games, ntoskrnl.exe error

miki86 · 26 Nov 2011

Hi,
I could use a little help here because this is really getting on my nerves.

The problem occurs when i try to run a game. Everything goes smooth to the part when bsod appears, usally after 10-15 minutes, depending on a game im trying.

At first i thought it's video driver that is causing trouble, but after changing several of them the results didn't got any better.

My system specs:
MB: MSI K9N SLI-2F
CPU: AMD Athlon x64 6000+
MEM: 4gb (Kingmax 2x1gb + Kingston 2gb) DDR2
VGA: Powercolor HD6850
PU: Chieftec 450w
Sys: Win7 Ultimate x64

What i tried so far:

Changing video card drivers (with or without control panel)
Reinstalling a fresh copy of windows 7
BlueScreenViewer shows it's ntoskrnl.exe related
sfc /scannow fixed some errors, but some of them still appear and can not be fixed
memtest86+ 4.20, 6 passes, no errors reported
Video Memory Stress Test v1.7, only one pass, showed no errors
chkdisk displayed some errors i think but they were fixed

Files attached.

Any help is appreciated, thanks in advance.

Try to remove the 1 GB sticks and see what happens

Hi.

Update software\driver for nVidia Ethernet Networking Driver (nForce chipset driver)

Drivers - Download NVIDIA Drivers

Remove Bitdefender from your system.

Download,instal,use Microsoft Security Essentials with windows firewall.

Run SFC /SCANNOW Command - System File Checker You may need to run it 2-3 times to "fix" everything.

Download and install Driver Sweeper

Download the most recent software\driver for your ati AMD Graphics Drivers & Software

Uninstall ati software\driver,restart in safe mode,run driver sweeper,choose only AMD-Display and clean,restart in normal mode.

Install the new ati software\driver,restart.

Update DirectX

Read very carefully the instructions and run NVIDIA/AMD Video Card - Test with OCCT Post here the results.

Run RAM - Test with Memtest86+ Leave it to run overnight.

Finish and post back.

Is your system WHQL-Certified for x64?

So the PC was working 'fine' for X amount of time and then 'suddenly' started crashing?

Aside from drivers, have you installed any new hardware that would coincide with the time it started crashing?

The system file itself is rarely/never the cause.

Reinstalling a fresh copy of windows 7

Was re-install over the top, or a completely new/partition formatted installation?

Thank you for your fast replay.
Im trying everything that panais suggested, and will get back with results.

I didn't played games for some time so i couldn't notice. Windows it self is working ok, although i remember having some problems booting the system after updates were installed.

I recenlty bought graphic card, that's the last thing i changed on my rig.

It was a completely new installation on a formated drive.

I updated my chipset drivers and so far i didn't got any bsod's.

~~Problem is solved, at least for now.~~

Upload the new minidumps.

miki86 · 27 Nov 2011

Looks like it was a power problem.
I plugged in an aditional molex connector to my motherboard, i don't know how i missed that, and it's exactly for the vga stability.

Latest dump file attached.

That additional molex is normally only needed when your running sli/crossfire to allow extra power to your pic express slots. its not needed with a single card.

maybe your 12v rail thats powering your 6pin connectors to the GPU is on the blink.
