Boot loop on new build w/ 7700K, Z270 MSI Gaming Pro Carbon BSOD

Hey guys,

I've posted this around on a few forums and not got any luck so I'm hoping the Intel community can come through with the goods. I've got a brand new system and all of a sudden it's become highly unstable (and therefore unusable) due to being stuck in a BSOD loop rotating between several different errors. Whilst testing components we noted that crashes were also caused when inserting a USB wifi dongle and/or flash drive.

I've tested other components pretty heavily (and separately) but the CPU is a little trickier for me to isolate. We've checked for physical damage (bent pins and the like) and haven't seen anything. I also did a stress test before it got unusable and there were no errors or high temps there.

Any help would be greatly appreciated, I'm at my wit's end.

Computer Specs
  • Windows 10 Pro 64-bit
  • Intel Core i7 @ 4.20GHz Kaby Lake 14nm Technology
  • RAM 16.0GB
  • ASUS MG279Q (2560x1440@64Hz)
  • ATI Radeon RX 580 Series (MSI)
  • 465GB Samsung SSD 840 EVO 500GB (SSD)32 °C
  • Realtek High Definition Audio
  • Silverstone Strider Gold S Series 80 Gold 850W PSU

Speccy Link (From Safe Mode, in case it's helpful)

BSOD errors noted
  • Driver overran stack buffer
  • Kmode exception not handled
  • Recource not owned
  • Kernal security check failure
  • Reference by pointer
  • FLTMGR.sys
  • Quota underflow
  • Bad pool caller
  • NTFS.sys
  • Page fault in nonpaged area
  • DPC watchdog violation
  • System thread exception not handled
  • ++ a few which I've missed

Safe mode is the only way to be able to use my system for longer than a few seconds. The PC can't even remain stable for long enough to reinstall windows! Hardware-wise nothing has been tweaked beyond how it came in the box. Here are my specs, in case it helps.

Here is my report from System Information:

And here are my mini dumps:

When this issue began

This may or may not be related, but when playing PlayerUnknown's Battlegrounds (PUBG) I got a system lock up accompanied by a plain screen of flat colour (which may actually be close to my theme's colour: dark red and an audio stutter/buzz). Hard power-down is required. As my best guess, this was the when the BSODs started.

Recurring issue

Yes. If I can get to Safe Mode is it fine though. I can't recall a BSOD in Safe Mode. EDIT: It does crash in Safe Mode with USB insertion/removal.

Date of purchase

1 month ago, still under Warranty

Cause/Steps to recreate the issue

Turn on PC and it'll happen almost instantly. Some BSODs happen before you even get into Windows. Crashes even happen during Windows install process. The only way to reinstall was to take the SSD out and install Windows using another PC before putting the SSD back into my box.

Plugging something into USB will almost certainly BSOD it too.

What I've tried so far to resolve the issue
  • Win10's inbuilt memory test
  • MemTest86 (8 passes)
  • Tested RAM sticks individually
  • chkdsk + scandisk
  • Rebuild MBR
  • System Restore (BSOD during)
  • System Reset (can't do it sometimes, other times it BSODs)
  • Startup Repair (BSOD during)
  • Removed GPU, ran DDU and tried onboard GFX
  • Removed all other components and tested successfully separately
  • Updating all motherboard drivers and flashing BIOS
  • Unplugging front USB from motherboard
  • Updating SSD firmware
  • Tested another RAM stick from motherboard's compatibility list and still got BSODs
  • Win8 wouldn't complete an install either. BSODd during install (as does Win10)
  • Installed Win10 on same SSD in another PC and it went fine (ie the SSD is fine)
  • Ubuntu seemed to run fine off USB3
  • There may be more, sorry I've tried so much I've probably forgotten some of the things.

Everything seems to point to the motherboard being faulty but I've just got this gut feeling that because it doesn't BSOD (as far as I remember) safe mode it's not faulty. Before I send it off for RMA and potentially incur a cost for them not finding it faulty I thought I'd try one last time to find an expert who might be able to shine some light on this for me.

Thank you in advance for any help you can give me, I am so desperate to get this sorted out.

Update: I ran sfc/scannow again and I got a few errors once it'd finished.

Screenshot of Command Prompt and CBS.log.

Could this just be a failing SSD after all? Are there any other checks you can do to stress an SSD or check it more thoroughly?

Hi BattleCat: Thank you very much for joining the Intel® Processors communities and for providing that information. We are sorry to hear the PC is not working properly.



At this point basically you tried all the troubleshoot steps that we recommend in order to try to fix this problem. As you mentioned, normally this kind of issue is related to the board but the only way to confirm that will be by swapping parts.


Do you have the option to test your processor on a different board or test your board with a different processor?


Could you please test the PC without the video card? This is just to rule out a possible problem with it.

On the link below you will be able to see that the memory RAM that is fully compatible with the processor is: DDR4-2133/2400, DDR3L-1333/1600 @ 1.35V, please make sure that RAM is running under that configuration:

In regard to your inquiry, yes, the problem could be also related to the SSD. I looked for tools to do a health test on it and I found a link that provides some 3rd party applications to do that, hopefully you will be to use them. Other than that to test the PC with a different SSD/hard drive will be the next thing to do to confirm if that is the case:

Additionally, we can run a tool to test the processor, it will do an overall test on it including a temperature test so we can rule out a possible problem in that regard:

Thanks very much for the reply, Alberto.

The RAM is 1333Mhz, so there shouldn't be any issue there, I've also been in contact with MSI and they said there shouldn't be any issues with the RAM I have. I've also tested the system without a GPU and it still displayed the same symptoms through onboard GFX.

I have already run Samsung Magician on the SSD and that didn't return any errors. I grabbed Crystal Disk Mark and the Intel tool but between keeping the system stable long enough to run them and compatibility with the Intel tool it might be a while! That said, it just completed Crystal Mark and below is a screenshot of the results (do they tell any story to you?). Interestingly, the PC crashed within seconds of the test finishing. I'm not sure if that was a coincidence or not.

I'll post an update if I can get the Intel tool to work. Thanks again for your suggestions.

BattleCat: You are welcome. Thank you very much for letting us know those results and for the picture. Hopefully you will be able to run the Intel tool to confirm if the processor is working fine. Since the option to swap parts is not available, a replacement of the processor might be needed. In case you are interested in that option, you can always verify with the place of purchase if they have the chance to do that for you, or you can get in contact directly with Intel so they can further assist you with the process:

Thanks, Alberto.

I ended up taking it into a repair shop and they performed a few tests and discovered that the CPU was faulty. They put it on another board and it crashed that too, and tried a different CPU on my board and it booted fine. They got an advanced RA, tested the replacement CPU and it was fine. I'm set to pick up my PC tomorrow, I'm so glad this ordeal is behind me now (it's just unfortunate I had to pay to have a service team to troubleshoot it)!
