Getting errors on my PC now

[futurefields]

I think I might have a bad memory stick or something, I don't know. I noticed some games kind of running dodgy. So i try to run the Memory Stress Test in Intel XTU and it crashes everytime.

This morning I just tried to load up a bot match in Advanced Warfare and it blue screened just as the game was set to load, got this error:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3

Any insight?

Also Im not sure how i can test a bad ram stick. I only have 8gb of ram, 2 sticks. If I take one out, I will be down to 4gb which means most of my new games wouldnt run well anyways.

I think I might have a bad memory stick or something, I don't know. I noticed some games kind of running dodgy. So i try to run the Memory Stress Test in Intel XTU and it crashes everytime.

Well, even with just 4 GB a game will run, but if it is your ram causing problems, you will need to figure out if it is one of them or both of them, and get it (them) replaced.

Windows has a built memory test that can be configured on long it runs to try to generate an error.

Alternately, you can download and use Memtest86:

Lastly, you can download WhoCrashed and see if it can provide any additional info on the crash:

Well, the only decision you need to make is to replace both sticks, or test them one at a time. Running slower may be a pain, but it's better than all your games crashing, isn't it?

I ran the memory test in Windows 7 (mdsched.exe) and it said no errors were detected. Is this sufficient to be trusted that I don't have any actual errors on the RAM?

Another symptom is my display driver has been randomly crashing (its actually the thing that crashes when I try to run the memory stress test in Intel XTU) I havent tried reinstalling or updating my video drivers yet though because it just seems like something like that wouldn't cause these problems.

 

[Ketchup]

If you run the original memory stress test again, do you still get errors?

The intel XTU one?

Just ran it. It crashed again.

Download WhoCrashed in the first post I responded to (post #2), and see if it can narrow down the source of the crash.

Generally when testing for RAM errors, you want it to test the ram for a few hours (looping) to see if it can generate an error.

Are your CPU temps good?

 

[futurefields]

Yes CPU never runs nice and cool never seems to go over 60 degrees. I will check out that Who Crashed program next.

Bug check description: This indicates that the system attempted to access invalid memory at a process IRQL that was too high.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

Conclusion
--------------------------------------------------------------------------------

2 crash dumps have been found and analyzed. A third party driver has been identified to be causing system crashes on your computer. It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:

nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 350.12 , NVIDIA Corporation)

If no updates for these drivers are available, try searching with Google on the names of these drivers in combination with the errors that have been reported for these drivers. Include the brand and model name of your computer as well in the query. This often yields interesting results from discussions on the web by users who have been experiencing similar problems.


Read the topic general suggestions for troubleshooting system crashes for more information.

Note that it's not always possible to state with certainty whether a reported driver is responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.

Was there a recent Windows 7 update or Nvidia driver update that maybe caused the issue?

You can manually uninstall the Nvidia driver, or you can use a utility like this one to do it for you. Just download the newest driver (unless that is your current one and causing issues):

[futurefields]

I tried updated my Nvidia driver, symptoms are exactly the same. I have Windows 7 updating disabled. I just get a few of the updates when I do a fresh install of Windows 7 and then I disable it after that.

What are the model numbers of your video card and power supply, and how long have you had them?

 

[futurefields]

EVGA GTX 970 SSC and Rosewill Capstone 650 (650 watt 80+ gold). I've had the power supply since 2012, the GPU since 2015.

 

[UsandThem]

If your system was stable up until the recent crashes, and the crashes seem to happen when you place a load on your system (Intel XTU), my first guess would be your PSU is beginning to be flaky.

PSUs that don't just suddenly die, tend to start causing system crashes and instability (especially with a higher load) on their march to death.

If you have another PSU, or have a friend with one you can test with, that would be my first troubleshooting step if that was happening to my system.

Guys please see this video, it happened this morning. I walked away from my PC and came back and it was doing this -

That's clearly a GPU VRAM or system RAM error, which could be caused by a flaky PSU. Or a bad GPU or RAM stick.

Agreed, has to be one of those three with the GPU or PSU at the top of the list. I had a XFX 7850 video card do that exact same thing, and I RMAed it. They ended up sending me a brand-new unit so I guess it wasn't fixable.

windows memory diagnostic isn't very effective.
I would definitely try memtest
