[Manzoe]

Out of nowhere I get blue screens I had it in shop to be checked they couldn't find problem could anyone look and see if they have any idea whats causing them. This is just a couple of them seems to happen at no specific time or task.

BugCheck 1A, {41790, fffffa8001d74560, ffff, 0}

Probably caused by : memory_corruption ( nt!MiDeleteVirtualAddresses+8cf )

Hi,
Bugcheck 1A means a severe memory management issue occurred which may or may not be failed or failing RAM.

As I already mentioned you either have a corrupt driver or operating system or the ram is starting to or has failed.

I did see that the process at the time of BSOD was dllhost.exe:

PROCESS_NAME:  dllhost.exe

This is a Windows Process which is an umbrella for apps and services within Windows itself. This may indicate that windows is a little corrupted or a driver is causing the issue.
Your drivers could do with updating and checking I see updates available for your chipset (which is ultra important) as well as others.

Update your drivers using only the versions found here:

Edit: Under Intel Rapid storage driver you want the 2014 version.
Under chipset you want both chipset driver and Intel engine management driver. The rest are pretty straight forward as to which version to use.

If it's been a very long time since Windows 7 was installed consider a clean install and start afresh making sure you only use drivers from the support page.

If the bsod continues then you really need to check the RAM as mentioned before.

Been 13 days so its getting better. Your suggestions helped next week I will be able to check the memory. Any suggestions with this one.

Hi,
I couldn't see a driver mentioned, have you made any changes recently such installing something new?

Try running the sfc scanner again mentioned earlier in this thread.

Hi Kemical, This is not a blue screen but I was hoping you could tell me what this is and how to fix, it only comes up when I log on.

Hi,
the above probable cause relates to your network driver:
athrx.sys Tue May 5 08:30:13 2015: Atheros network adapter driver
I checked your support page but there isn't a later driver. You could try simply removing the current version and installing a fresh copy.
Your support page is here:

Please post any new dump files.

This link below contains a comprehensive description about the type of Blue Screen you are describing. It is basically indicating damaged operating system files. They go in to system recover from restore points and or recovery from a system image, and etc. Personally, I found when there are damaged files not caused by many improper shut downs there are faults with the hard disk. Hard disk faults can be intermittent. I would change the drive and restore the system from a last known good image backup. Do not make an image backup from the computer if there are faults! You can install a new drive and re-install if you do not have a known good system backup image.

I've done all the test and removed many programs and still having problem. All test performed passed shows no hardware errors.

Hi,
when you say you've done all the test, does this include testing the RAM too?

Looking back over the dump files posted and the collective bugchecks as a whole could indicate a RAM issue.

Please run Memtest86 as outline in this guide: How to Test PC RAM with MemTest86

 

[Manzoe]

My son ran the memtest 86 for a couple of hours and found no errors, it made a couple of passes. I don't have visual studio on this computer so couldn't do anything with that.

Ideally memtest86 needs to be run overnight like for 8hrs or so.

Also sometimes there are errors that even memtest86 won't pick up and it might be worth running the system on one stick of RAM at a time. If the system still blue screens swap the stick over for another and use the machine again. The idea is that your looking for the stick which doesn't bsod meaning the other/s are faulty.

You could try some basic bug testing.

Personally I would try re-installing the os especially if it's been a long time since it was refreshed. When i mean re-install I mean by the clean install method which wipes the drive clean.
You then add the drivers but nothing else, no third party apps and see if the machine blue screens.

If all seems well slowly start adding apps back, one at a time, checking on blue screens in between each install.

Been awhile since I had a blue screen and now I had 3 within short time. Everything you recommended was done and seemed computer was running well until this past week. Do you have anymore suggestions now for this problem? Thanks for all your help

Hi,
of the three dump files sent, two are like the above.
Usually the above is caused by a driver although which driver is unknown.

Have you recently made any changes, either driver, application or hardware?

One way to determine the offending driver is to run whats called the driver verifier:

Driver Verifier - BSOD related - Windows 10, 8.1, 8, 7 + Vista

Post any new dump files.
