Multiple BSOD with different error messages

Question

For a while I'm having trouble with constant BSODs in my computer. The most common is: SYSTEM_SERVICE_EXCEPTION dxgkrnl.sys; IRQL_NOT_LESS_OR_EQUAL; KMODE_EXCEPTION_NOT_HANDLED USBXHCI.SYS; DRIVER_IRQL_NOT_LESS_OR_EQUAL pacer.sys -- it's some of documented in past days, but it's certainly not a full list.

I tried to reinstall windows, drivers for motherboard, drivers for video card. nothing worked. Usually I'm having BSODs around 1 per day, before certain windows updates it was 1 per week or two. I tried sfc /scannow, It didn't help. I tested all RAM modules with MemTest, 0 errors.

My PC spec:

Windows 10 Home

i5-4670k

MSI B85 G43

16 gb RAM Kingston KVR16N11S8/4

GTX 960 2 gb

Answer 1

I've examined the dump files, thank you. The results are in the image below. There's still a need to isolate this, but based on these results. The issue could be either one of the peripherals (mouse, keyboard, and other devices connected to the computer through USB) connected to the computer, it can be the ports of that computer, or worse, you have a defective motherboard.

You have already reinstalled windows and even update your board drivers, this issue must be hardware.

Hi, thank you for help, but I need my computer for work, and, since usually I have 1 BSOD/day or less, I need to leave my computer in safemode for that long, and I'm not really sure I can do this. Is it possible to determine what exactly component failed? I will try to replace it and see how it goes.

Here is all dump files that I have: https://1drv.ms/u/s!AsJuzs3Scw4LZwggUC6GrRYhOzU?e=hX1CIy , including the last one that I've already sent.

Answer 3

Hi,

We're going to have to isolate this. I examined the dump file you sent, it returned hardware at fault. Anyway, let's start by observing your computer in safemode for now. If the BSOD is random and occurs even the computer is idle, observe it under for a couple of hours. To go to safemode:

-Win + R to open run box

-Type: msconfig <Enter>

-Select Boot tab

-Check Safe boot

-Hit Ok, then Restart the computer

Let me know how that goes.

Hi, here is a full dump file dated 22 February. I see that it is created at 17:08 by my timezone, and it's exactly the time when yesterday crash happened.

More recent files I do not see, so it's the most recent one. If you need any other information, please tell me, I will give you all that you need:)

Thanks for reaching out. My name is, Zadee. I'm an Independent Advisor and a Microsoft user like you. I'll be glad to help you today.

Please share the recent dump files here. At least 5-10 dump files will do. You can find them in C:\Windows\Minidump

Then upload them to any cloud storage like OneDrive and share the link here.
