Nvlddmkm.sys one day after freshly reinstalling system

[Stteffann]

The main reason I reinstalled the system is to not have Nvlddmkm.sys show up. One day after reinstalling, there it is again. Windows 7 Pro SP1 x64. How do I create and upload an error log?

Hello and welcome Stteffann is the error accompanied by a blue screen??

 

[Stteffann]

Yes, it was a blue screen!
BTW, my PSU exploded this morning, I think this could have been the cause of the problem... I will buy a new power supply Monday.

 

[Stteffann]

Also, I remeber the PC beibg unusually noisy, VERY noisy, I assume it was the cooler inside the PSU that was problematic. It could be that the cause of the problem was hardware, not a driver or malware issue..

 

[ICIT2LOL]

Yes mate it really could have been the problem but bit late to use my little check ditty for it. The noise could have been the cooling fan and or the caps going south as both can get extremely noisy when at fault. Thing is the PSU is one component very often forgotten when issues arise and it is always wise to just keep a check on the state of it as I have pulled some out that are so full of dust hair and general crud it isn't funny.

Now just a word of warning DO NOT ever attempt to disassemble a PSU unless you know what you are doing because inside there are lethally high voltages very similar to those used for resuscitating heart attack individuals and those defibrillator machines are designed to actually stop the heart in an attempt to get it back into a natural rhythm and the same happens if PSU's are handled by the unwary to foolish people.

See what the new PSU does to improve things but if you want you can attach BSOD dumps with these

Is the PSU dangerous to open even when completely disconnected from the computer? Does it have any internal charge? I wouldnt open it either way since its still under guarantee since its just 9 mts old, I might get a free replacement. But I think I will switch to another brand since this seems like garbage, no wonder when it costed around 15€...

 

[ICIT2LOL]

Yes Stefan some can hold the charge for days and even when disconnected from any mains power supply.See pic
Now if you are in the market for a PSU then use this to find out what size you may need it usually exceeds what you need as a safety margin - you may add more components in the future
OuterVision Power Supply Calculator type in what will be in the machine and it automatically works it out for you and by the by get a good brand PSU it is worth it in the long run.
Myself I like Corsair, Thermaltake, Coolermaster, Seasonic - the one that you have looks to be oen of those awful OEM ones that come with the case.

A good article if you are interested is this https://en.wikipedia.org/wiki/Power_supply_unit_(computer) - there is a good pic of the 24 pin output volts should you need to know what is what.

WOW, I had no idea! I used to open old PSU when I wanted to remove dust... Never knew how dangerous that was haha!
Yes, I will consider Cooler Master or Thermaltake! Thanks for this info. I'll buy one tomorrow and report back on results.

 

[ICIT2LOL]

Just as well you asked mate I have had some near misses myself while rigging some up for a power supply source for testing fans, spinner hard drives etc etc That is not encouraging you to do the same just best left alone really until you know exactly what you are doing with them.

Yep my particular favourite is Corsair to be honest but Seasonic are good. Having said that many are made by the same companies and I am guessing the the brand people are in control of the manufacturing specs so one brand made by Joe Blow may be more precisely made than another made by Joe

Anyway that calculator will show you what size you need to get.

 

[Stteffann]

Ok, I underestimated the prices of Thermaltake and Cooler master PSUs, by FAR! I can't afford those, so I bought this one:
Gigatron - ZEUS Napajanje 560W ZUS-560 - Napajanja za računare - Napajanja
So far, the computer works well and does not sound noisy, I would say that the problem is resolved.
I'll post the Bluescreen report.

 

[Stteffann]

Ok, here's the report!

 

[ICIT2LOL]

Ok Stefan it may well have been the PSU all along. Now I don't understand the currency mate because RSD 1.99 equates to AUD$0.25 unless I am calculating the wrong currency of course because 25 Australian cents for a PSU seems hardly credible.
For example this would be a fairly ordinary PSU that I would put in a low work machine https://www.pccasegear.com/products/21569/corsair-cx-500-v3-power-supply. Personally for my machine I would spend quite a bit more because I want the peace of mind - somethng like this https://www.pccasegear.com/products/28764/corsair-hx750i-750w-80-plus-platinum-power-supply

Now in the report there are no BSOD dumps and the only thing that sticks out to me because a lot of the info is real techie stuff is that there are no Blu tooth drivers installed in msinfo log under problem devices.
Just try following those two tutorials again because the blue screen iif it was not just a steady blue one with no text is probably not a true BSOD.

Haha, if only! 1 AUD is around 84 dinars...Both are expensive for my budget, especially the second one haha! The average salary here is around 560AUD so you can imagine how prohibitive the second price is...

I do have a USB bluetooth, a small one, and I didnt get a drive CD with it, so that could be showing up as a problem but I used ut for at least 4 years, no problems with that...

Maybe the BSOD report was deleted by Ccleaner, I use it quite often without thinking, and that program even clears the Recycle bin completely so it could be the one to blame for the bluescreen report not existing in the archive. For just in case I will try posting again but I expect the exact same result.

 

[Stteffann]

Here it is again...

 

[ICIT2LOL]

Hmm sorry re the pricing on the PSU mate I didn't mean to sound rude or anything and if you lived a bit closer I could give you one of my spares I have collected over time that would have been good to go.

Still no BSOD dumps in that zip file and I am not sure if CCleaner does in fact clear BSOD dump files - it has never occurred to me to be honest. So the BSOD screen did it look something like what is in the pic attached?

The BSOD dump files show up as in the other pic and have that typical small blue computer like looking icon

 

[Stteffann]

There's nothing to apologize for! BTW, we couldn't be further more away from each other!
This is what the screen looked like:

 

[Stteffann]

Also, CCleaner DOES indeed remove dump files! So that is why there was nothing to show...

 

[ICIT2LOL]

Ok I see now re the CC and if that is the actual blue screen the machine threw then it states in it there is an issue with the NVidia graphics as you can see from my snip/ pic

The usual suggestion is to update the driver for the GPU.

I don't think it was the driver. I would say that the computer shows this for this behaviour, but it could have been because of the instability of power supply to the graphic card, since all the elements on the screen switched in opposite direction and the screen started blinking about 3s before the PSU exploded. So I think it's just the instability that casued this to appear. Now with the new PSU, there are no BSODs, and by the way, I DID download the latest driver from Nvidia site directly, so that could not be it. I think that it is safe to say that the PSU was the main cause, so reinstalling the system was not really neccessary because there was no malware that caused errors. Thanks for all the help!

 

[ICIT2LOL]

Ok Stefan you are probably right and that it was the power to the GPU being the issue the error numbers following that .sys would in all intents would mean just that to someone who is a lot cleverer than me at decyphering those things.

Now if the new PSU does fix the problem then we both have learnt something eh? because I only do this and build for a hobby.

Pity as usually one of the first things I ask in posts is the health of the PSU and it is more often than not missed as a machine's problems.
his is what I usually post
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT as a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE (sometimes the usual one for Gigabyte boards)
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/-
12v = 11.4 – 12.6v
5v = 4.74 – 5.25v
3.3v = 3.135 – 3.465v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

The link within this is good reading and just as a by the by you might find this helpful too in getting the most out of your machine if you don't mind losing a bit of "bling" like transparency
