    Bsod

    I have had a BSOD a few times over the last couple of months. I used NirSofr Blue Screen Viewer for this screen shot:

    ntoskrnl.jpg

    I realize this is a file necessary when Windows boots, but what would cause the BSOD with ntoskrnl.exe pointed out well after the boot is complete (several minutes to hours). If any of my learned colleagues has a suggestion I am all ears.

    I might be suspicious of a RAM issue. Here is a link to discussion of a potential solution. Guess this might extend to HD or SSD in some cases but not sure.

    You probably have already done this but a Google of "ntoskrnl.exe blue screen 0x0000001a" will get a number of hits.

    Ted, I'd try running either Memtest86+ (preferably) or Microsoft Memory Diagnostic overnight, having booted from the appropriate created CD/DVD/UFD... These manage to pull out many memory faults, and if you find nothing that reassures you that your memory is (probably) OK!

    Ok, here is what I have done so far:
    1) swapped RAM chips and reseated several times
    2) ran Windows memory test in boot
    3) downloaded and ran memtest86 v4.0a (approx 1.5 hours to complete 2 passes with no errors detected.

    Started PC again and got another BSOD this time ntfs.sys file failed.

    4) returned RAM chips to original locations.

    continuing to use PC. will update if problems continue.

    Ted, if the BSOD is constant, I would try the Clean Boot Diagnostic procedure (ignore the fixit that pops up) to eliminate any driver and installed software conflicts.

    Are there any clues in the Event Viewer?

    It is definitely not constant and does not occur during boot, but at some time (usually minutes to hours) after while I am working or surfing, etc. Very intermmitent. Generally not a big deal, but if I can figure this out, my knowledge base improves. I thought it might be a memory problem as well, but memtest86 shows no errors. And the next BSOD (this is the first time I have seen 2 in one day, they usually are days or weeks apart) showed a ntfs.sys error. I do have very few apps starting with windows (only 4 including my AV, S/W firewall, Touchpad and Logitech mouse S/W) I will post back when this occurs again and see if any more clues present themselves.

    You might also want to take a peak at the Windows 7 Reliability monitor. Click on the start orb, type reliability and click on View Reliability History and see if there are any failure patterns. I assume you don't have an image prior to the BSODs? i realize you haven't had any issues with your firewall prior to this but you might want to disable it and enable the Windows firewall for a day or two as a test.

    I do not have an Image since my last update (Imaged last on 8/15) I have seen these BSOD for a while, quite intermittently. The reliability monitor did show 2 windows error today but are not easily understood. I may try to restore to the 8/15 Image and start from there again and see what happens. I'll post back if any further clues appear.

    "Intermittent" could perhaps mean overheating? I presume you've checked for dust/fluff/mice inside the case. Might be worth running CoreTemp to see how hot things get?

    I just checked temps using SIW. They seem to be well within normal limits. This is a laptop so it's somewhat more difficult to clean, but I have done this as best as I can. I have not attempted to open the case up more than going through the access doors.

    The temps do vary but always stay well below the max listed values.

    IMHO, WhoCrashed won't tell you much more, if at all, than BlueScreenView does, Ted. I actually find it more unreliable than BlueScreenView.

    Can you think of any change that occurred near the time you start experiencing this? AV, Firewall, drivers, etc?

    It has been very intermittant for quite some time. I just decided to try to figure things out now, so no I can think of no change that took place. It generally only happens every few days or sometimes weeks apart so it's not been a big deal.

    Thanks for the review of WhoCrashed. When it happens again I will check both. Nothing I have found makes interpreting these things very easy. Like I said this really has not been a big deal. I'm generally not doing something I can't afford to lose when it does happen. If I'm here, the Auto Save feature works great. I'll keep plugging away. Perhaps at some point in time an answer will present itself.
