BSOD - nvlddmkm.sys / dxgkrnl.sys

[doingworkallday]

System consistently blue screening for the past month or so. I thought it was a faulty system file and ended up replacing old SSD, buying a new motherboard, installing a new copy of windows 7 ultimate (upgraded from windows 8.1 ) and replaced my RAM twice. and after all this nonsense I'm beginning to get the errors again. I have run memtest over and over and come up with nothing. Ive run through these forums enough times and tried installing and reinstalling drivers enough times that I have run out of options and am in need of your help please.

Hello and welcome doing I don't know jhow old your machine is so one thing it looks like you have not tried out is the PSU.
Now I have two options to view to see if the power output

Using HW Info PSU

Download HW Info and pick the right bit version - HWiNFO, HWiNFO32/64 - Download -(copy and paste this site into the search bar) If you do not need the running information in the smaller right hand panel close it. In the left hand window click on the + for the individual device groupings and they will open out to the various components.

Go on opening out further until you get to the device itself. click on it and it will highlight. In the right hand window there will be a very detailed description of that device as in brand, speeds model number etc etc These are very detailed and are just what is needed for searching for drivers etc.

See my pic for an example - in this I have shown my power but it is a laptop and a desktop will show more details if you scroll down that listing. Now if your mobo is an Asus scrolling down that Sensor listing you might come across a section titled FINTEC that is the section which will give you the rail voltages and the BIOS battery called Vbatt

An alternative is this bit please use a digital meter and NOT an analogue one as they inject typically 9v into a circuit to test it and doing that on a 3.3v or 5v rail will not do anything any good!!

I completely forgot to mention I just bought an AX860 a week ago thinking that might have been a problem. So currently as it stands everything in my pc is a week old besides graphics card and cpu which I bought a year and a half ago.

Ok mate well that rules out just about the PSU -very nice choice by the way

Now where to go next?? Just one question the media you installed the Ultimate from was it retail or an OEM? and genuine Microsoft - not being funny but there are some who buy from sites like Ebay to their regret.

 

[doingworkallday]

It was retail. I have run benchmark tests on my gfx card and it comes up with no errors and tops out and 82°c

Additionally,

Disk or file corruption seems to be a common theme in your dumps as well as memory.

Are you using Memtest86+ to test your RAM? 8 complete passes is necessary.

   Information

MemTest86+

Run a minimum of 8 passes, preferably overnight, or until errors occur using MemTest86+.

Use this tutorial to help you use MemTest86+:
RAM - Test with MemTest86+

Please perform the following tests,

chkdsk /r

SeaTools for DOS and Windows

I have run memtests already on all 3 diff sets of memory sticks each of which have worked in other computers and passed on the test. Sfc check comes up with nothing. And chkdsk comes up with nothing I'm honestly confused and have pretty much entirely rebuilt the computer from scratch besides gfx card and cpu.

 

[ICIT2LOL]

Ok D mate I don't know if you have run any malware scans but if not try these

http://www.superantispyware.com/

http://www.malwarebytes.org/products/malwarebytes_free/

http://www.bleepingcomputer.com/download/adwcleaner/

download from bleeping computer – delete any rubbishthese find.
if these come nothing then use this
Download Kaspersky Rescue Disk 10 just boot from this disk / USB I prefer the disk but.... It will scan from power up and before Windows which isn't involved anyway starts.

 

[doingworkallday]

Nothing came up as far as viruses or any of that. Not sure what else to do

 

[ICIT2LOL]

Well it has me a bit stumped too now.

The only thing I can suggest now is back up and re install and try using this
http://www.sevenforums.com/tutorials/219487-clean-reinstall-factory-oem-windows-7-a.html#post1839164 cos I suppose there is always the outside possibility that the media you have is corrupted??

 

[doingworkallday]

I bought windows 8 and a seperate copy of 7 and they both ended up like this on two seperate clean harddrives and I clean reinstalled twice on both.

 

[ICIT2LOL]

Now I am really getting bogged down D and I am wondering maybe the optical drive is not up to scratch? Something is really wrong if you have used two new OS's and two new drives, and on a new motherboard and it still keeps blue screening.
I can only refer back to that tutorial and you making an ISO from the download site onto a USB stick and boot from it.

Now one thing I have just thought of is to try this and if it blue screens with it then it has to be some hardware issue we are missing.

BOOTABLEUBUNTU

Makea bootable Ubuntu disk http://www.ubuntu.com/download

Setthe BIOS to boot from the optical when the machine boots it will show you ascreen with TRY or INSTALL > select TRY. You can of course remove the hard drive and any otherdrives when doing this as if the optical alone is the only drive left in themachine then the BIOS will only find it to boot from.

Whenit is finished - it takes very little time you will get a screen like in thepic .

Openthe drive you want > User and dig down until you get to the data / settingsyou may be able to copy / paste the material you want to an external source orother installed drive doing this.

Iam not sure if it will but I have recovered tons of data etc using this methodboth on "dead" or just plain drives that you cannot get data fromusing Windows.
If you get the screen as in my pic and it does not blue screen at all then the hardware must be working ok and the software is not. Just remember to use TRY not install. It may seem like the long way round but it will show if the hardware can work with an OS of a sort.
