Windows 7: Surge of BSODs Since Yesterday, Seemingly Random

Surge of BSODs Since Yesterday, Seemingly Random

Hi!

I have a 15" 2010 Macbook Pro with Windows 7 x64 Home Edition installed via Bootcamp (separate hard drive partition). Since yesterday, I've had at least 8 BSODs caused by these files: "ntoskrnl.exe", "bcmwl664.sys", "ntfs.sys", "ndis.sys".

From what I understand, all of these files except for "bcmwl664.sys" are part of the OS so I don't know what to do to fix the errors. "bcmwl664.sys" is a Broadcom 802.11 Network Adapter wireless driver, but I checked and I have the latest driver installed.

I initially was using windbg to analyze the crash dump files when I started getting BSODs, but then I downloaded WhoCrashed and started using it instead.

Since the last couple of BSODs, WhoCrashed seemed to not report a couple of earlier BSODs I had. Initially I had the Network Adapter crash, an Apple Trackpad crash and another Apple driver crash (which I had the latest drivers of as well. Apple Automatic Update didn't give me anything to update), and only a couple of BSODs that were caused by OS files. Now all the BSODs except for the wireless driver one are caused by OS files. Maybe the Apple ones were overwritten by the new crash dumps?

Also, I used to have regular BSOD crashes that appeared as black screens due to the graphics driver crashing. I had the latest graphics drivers, but after searching the internet for solutions, I found that if I manually increased the timeout for the graphics driver to respond, every time the graphics driver crashes, the screen will just go black for a few seconds and then recover (which isn't ideal, but it's better than losing all my data in the crash). The crash dump dated 8/8/12 was one of these crashes. I don't have more of them because I recently wiped my computer and reinstalled everything. The following couple of weeks I didn't have full BSOD crashes (just the video driver failing and recovering).

I'm not sure what's causing the BSODs. I've had two of them while video chatting, one while surfing the internet, one when I was coding in Visual Studio 2010, and one while I was watching a YouTube video, I don't quite remember the details of the others, but I'm pretty sure they were just random things. I hadn't installed any new software before the crashes.

Let me know if there's any other information needed. Please help!

Welcome
One report indicates memory. The others may be hinting at memory. Take a memory test.
Run for 8 passes.
Then test each stick in a good slot for 6 passes.
If you have dual channel, the results may be incorrect, if shows pass.

Thank you for the prompt response!

So I ran the TechTools Deluxe analysis for Macs that comes with an Applecare Protection plan and it said all parts of the computer that it tested passed, including RAM.

I'm currently running Memtest86 v4.20 after following the instructions given. I burned the bootable ISO onto a DVD, turned off the computer and removed one stick of RAM, and booted up Memtest.

So far it shows over 1,000,000 errors and counting, 0 passes. Does this mean I have bad memory? I don't understand how it could possible function at all if every address is failing.

After the 1,000,000 errors I restarted the computer thinking that maybe I seated the memory incorrectly, but it booted just fine and is running fine so far.

I tried placing the memory in the other seat, but I got the same mass-error failure. Then I tried using the other stick by itself, and then both sticks at once, but they all failed.

Could it be possible that Memtest doesn't work correctly with Macs?

I attached an image of a photo of the screen.

Oh yeah I know, but my mac is running Windows effectively as a PC. My hard drive is partitioned with something like 350 GB for Windows and 150 GB for OSX. I wouldn't be able to get BSODs unless I had windows.

Or at least I thought that Windows 7 and PC aren't necessarily synonymous. It all just comes down to hardware run by software in the end (right?).

If I'm getting all errors for the first pass of my memtest, does that mean my memory is definitely the reason for the blue screens?

That is a question that no one can answer.
I can say that memory problems are definately a big cause of BSODs and that your reports, at a minimum, hinted at memory as the cause of your BSODs.
The only thing that I can suggest, get the memory problem fixed (and I think that the BSODs will be history). If not post, again in this thread and I will be notified and will help if possible.

Getting BSODs at random, but it seems as though most of the time it's because I alt tab into or out of a full screen program. This might of course be confirmation bias. Got this when I logged back on, maybe it can help: BCCode: 3b BCP1: 00000000C0000005 BCP2: FFFFF96000164283 ...
