Random blue screens - Hardware problems?

I have been having random blue screen shutdowns on my system. It all started when the electricity went off unannounced. My PC is attached to an APC battery but I have a feeling something did not shut down right. Now my computer will run normally for a random period of time ranging from half and hour to several hours and the crash with a BSOD and restart... The BSODs are for random issues...

I have run memtest, FurMark (for vga issues), and other utilities to check the potential of memory issues, vga, SSD issues, etc. Ironically all tests managed to complete and succefully. I wonder if there is a full on suite that can run an exhaustive search to test potential processor or motherboard issues. Any food for thought?

I am attaching some of my bsod dumps...

The dumps are all different. I'd check the BIOS settings, maybe something is being overclocked or you have a wrong setting somewhere. Also check the system is properly cooled. do a BIOS upgrade, or just flash the same BIOS again if it already uses the newest BIOS. What memtest did you use? Only memtest86+ is reliable. Other memory testers I've used showed no problems although a memory module actually was bad. Only memtest86 correctly informed me that is was bad.

That problem with the RAM was on a similar mainboard (Asus z87m-plus) as yours. I also had other problems (not powering on at times), and after I reflashed the BIOS it has been running without any issues.

Another thing I'd recommend is to download the newest drivers for your mainboard and reinstall them.

I used memetest86+ for the memory test and have confidence in the memory at this point. The issue is so random that I doubt it is memory related.

Somehow I did not think to flash the bios as I have had an issue some time ago and thought resolved.
Will do that and see what happens...

You can download a free tool called BlueScreen View that will allow you so see the BSOD log in detail and English!  

BlueScreenView v1.55
Copyright (c) 2009 - 2015 Nir Sofer
Web site: http://www.nirsoft.net

Description
===========

BlueScreenView scans all your minidump files created during 'blue screen
of death' crashes, and displays the information about all crashes in one
table. For each crash, BlueScreenView displays the minidump filename, the
date/time of the crash, the basic crash information displayed in the blue
screen (Bug Check Code and 4 parameters), and the details of the driver
or module that possibly caused the crash (filename, product name, file
description, and file version).
For each crash displayed in the upper pane, you can view the details of
the device drivers loaded during the crash in the lower pane.
BlueScreenView also mark the drivers that their addresses found in the
crash stack, so you can easily locate the suspected drivers that possibly
caused the crash.


Hope it helps... It did for me.  I had a few Dell Computers that the Radeon video driver was the problem.

i don't use bluescreenview anymore - it gives not enough info for me - or even wrong one
9421 dmp says : memory referenced, and points to PROCESS_NAME:  audiodg.exe
34921 :  SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION     PROCESS_NAME:  chrome.exe
12796 : CRITICAL_PROCESS_DIED

you can test with only 1 ram stick installed; and if that runs without problems, test each of the others

if nothing is found -  you must consider the possibility that the OS is damagedas a 2nd step - i suggest to test the disk also - so you're sure about the basics; i use the UBCD for this :
Hardware diagnostic CD    UBCD
---------------------------------------------------
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

http://www.ultimatebootcd.com/                        ultimate boot cd
http://www.ultimatebootcd.com/download.html             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems : http://www.experts-exchange.com/Storage/Hard_Drives/A_3000-The-bad-hard-disk-problem.html

***if booth disk and ram are ok - run chkdsk also on the drive

Issue was related to BIOS as I changed the image and it works fine now.
Thanks
nobusCommented:
what image did you change?  may we know?

I went one BIOS release back... I suppose it depends on the type of motherboard. Mine is an Asus z87-A. I think at some point I "upgraded" which probably did not sit well with my board. It maybe coincidental but the Windows 10 upgrade aggravated the situation....
rindiCommented:
In my situation when I reflashed the BIOS, I used the same version I had already installed. Something must not have gone optimally when I first flashed it. So maybe if you use the newest version it might work properly now.
