Solved BSOD League Of Legends, Memory management error 0X1a

Heya,

As the title states: I get BSOD when i'm doing anything with LoL, I have reinstalled a clean OS, and downloaded/installed the game. After that I finished installing the drivers and now LoL cant seem to play a game, it will run but I will BSOD as soon as the game starts.

I have uninstalled many drivers that I installed at start except three: 2 GPU drivers, and one intel chipset one. The rest I have uninstalled through device manager, and unfortunately I still BSOD in-game.

I have done checkdisk twice, came out clean, did a memory test with the windows application also came out clean.

The BSOD unfortunately starts only when downloading anything from the game or playing a game.
I would be really grateful if someone could help me out with this, its becoming really bothersome and I am planning on reinstalling the OS again if it continues like this.

Hello asif343.

Your issue is the display drivers here ... both of them are failing.

Intel HD Graphics driver ...
Nvidia display driver .....
At this point, I would suggest you to first try a clean reinstall. Clean Reinstall - Factory OEM Windows 7 .

Suggesting it, coz the pre-installed laptops with dual graphics uses some complicated settings for display usage, which itself may cause those errors.

While installing the display driver, perform a clean install only.



Let us know the results when done.

Hey, Thanks for your reply.

I have done exactly as you said, a new OS installed cleanly, then installed the most recent intel HD 3000 driver, and the second most recent nvidia driver (clean installation)

Unfortunately the error has not receded and its still active this time I got a different crash twice, in both cases a kernel dump so those are quite big files.

On Sat 8/31/2013 8:09:54 PM GMT your computer crashed
crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: [FONT=Segoe UI, Arial]Unknown[/FONT] (0x00000000)
Bugcheck code: 0x4E (0x99, 0x4F6, 0x2, 0x2318B5)

I also downgraded the bios after updating it to the highest version, the reason I did that was because the newest version didnt really solve my problem, so I thought maybe i need to downgrade it and test it with another version.
Apparently this did not fix the crash and its still happening.

As you stated, its the videocards, I thought it was the 'optimus' driver, I searched for drivers for that, but apparently those drivers are included with the complete package.

I'm going to do another clean install of video driver, this time the old ones from acer's website.

EDIT: I have tested the videocard drivers on acer's support page, it also didnt work, this time I managed to get the dumpfiles; the zip file is attached.

Update your NETGEAR WNDA3200 Wireless 11N Dual-band USB Adapter Driver. It is too old, and failing.
Search for possible updates in Global Download Center.
The intel Graphics Driver is still failing there. Better you would try to use the windows 7's default settings. Ues either GPU. If the display transition will be present there, there will be app possibilities of failure.

It may be supposed that the Optimus technology will help you in battery saving etc stuff, but in turn it will make the system crash prone at its own virtue.

In this case I would have used the nvidia GPU only, at least as a test.

About the wireless dongle, there is sadly no form of update for that, I had researched that and couldnt find anything, but I did find an atheros update for it? Might work with it (someone in virgin's official website said that)

How do I use windows 7's default settings? Either GPU? In the bios I have selected that option.
Also how do I configure this computer to use only the nvidia GPU?

Many thanks!

Edit: After installing the latest drivers for the dongle, and also configuring through the nvidia control panel that the dedicated videocard should be used, the BSOD still occured, except this time a different error.

Yes, I also think that no update to your dongle is available. There are updates for WNDA3100 v1 and v2, but not for WNDA3200. In that situation, the only feasible solution is to replace the network adapter.

This latest BSOD is point out to a Memory Corruption prima facie.
But still there is evidence of Intel Display driver failure.
You disable Intel display. Use the Nvidia display only, and always. Also dont use the optimus technology. Windows 7 does not need multiple GPU configuration, display transition etc to run. You should observe how the computer is behaving when there is no added complication.

If still there is issue, RMA the computer.

For the memory corruption indication, be in safe side. 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.

unfortunately I dont have warranty on this laptop.

I have uninstalled the drivers of the intel one and installed it from acer's main website, this time the intel drivers took a different name than before intel HD graphics family.
This still didnt manage to stop the crash, but the BSOD has a different name now, anyway the next thing I did was downgrade the bios to v1.03, the reason for that is: to upgrade the vbios and just to go ahead and check if it would work.

The BSOD is attached.

Now I have reinstalled the nvidia graphic card drivers in order to see if its optimus is going to reconfigure to the intel drivers, hopefully making it work. I'm now going to test this and hope for it to work.

Do the memtest for 8 passes?

i'm planning on doing that later on today, but i'm sure that the memory isnt the case, because these BSOD's only occurred after I reinstalled windows.

Heya, ive done memtest an apparently nothing came out of it.
It said the memory was clean. I cant do an RMA since this product doesnt have warranty anymore.

Update the BIOS to teh latest again. Keep it there.

You have the clean install, before I suggested then, I guess?

Do it once again after updating the BIOS...... follow Clean Reinstall - Factory OEM Windows 7 .

Heya,

Ive done a complete reinstall, I have reseated the ram, reinstalled all the drivers to the latest and disabled the dedicated videocard, now the pc works on the intel one without any problems.

but when I try to start up the dedicated one, then it suddenly blue screens when i play a game, so its definitely the nvidia videocard, perhaps the drivers are terrible and the optimus is really bad?

I'm going to reinstall the graphic drivers to an older one and basically try to test the drivers from there on upwards to the latest, and find out which one solves the problem.

Good, let us know about your experiments. It will help others too

Lately we have seen a lot of issues with Optimus.

Well I think its a success, Ive done a couple of things, let me start with the first one;

I did a clean reinstall on windows, afterwards I started to manually install every driver, and the intel integrated graphic card one I did from the laptop's manufacturer's website, and the dedicated videocard doesnt really matter, update it, lets say to the latest?

Secondly I reseated the ram (took it out and placed it back in).

Next I went directly into the bios (restart and press F2), there I switched off the dedicated videocard and chose only the integrated graphic card. I did this to test the integrated videocard, to see if there were any problems with it, after starting it back up and trying out LoL no problems happened, I could finally play games, although the fps was quite lower than using the dedicated one (which is obvious).
But now I was sure that it wasn't the integrated video card which was failing, but it was the dedicated one which forced the integrated one to fail (Optimus).

So this time I went back to bios (restarting and pressing F2 or whatever works on yours), and switched the graphic card option back to 'switchable'. Now I saved the settings and restarted the pc and another problem occurred: the pc would stick at a black screen. My fix to this was by reseating the ram again (taking it out and placing it back in again).

This time the laptop started properly and I was back into windows, what I did now was uninstall the dedicated videocard and its drivers (in device manager, right click the videocard and then click uninstall). Then restart the laptop again after finishing that.
Once the laptop restarted, I went directly into the dedicated video card's manufacturer's website (Nvidia) and downloaded a WHQL-driver, I think mine's 320.49? I'm not sure, but I just installed it and ran the .exe
Anyway, instead of choosing express install, I chose custom one, here I unchecked the geforce experience (note: I did not check the clean install) and I just went ahead and completed the installation.

I also downloaded another program 'Nvidia system tools', I installed this and opened up the control panel, here I accepted the agreement and changed only one thing: device setting > set it to custom > graphics clock to 650 instead of 672.

Finally I restarted the laptop and it seems to be working fine now, but the fps is now lower than before (normally 180 fps in-game but now its as low as 20 and occasionally it jumps to 100). I'm still going to search for the problem, but after I had done these steps the BSOD's have completely disappeared and I can play LoL. I am going to test a game that requires better graphics and see if that will run without any problem.

Anyway I hope this works for the people that read it.

Thanks for sharing your way, Asif. I wish it will be helpful to a lot of users having the similar issue.
