Issue started as frequent BSOD, then no display signal, now constant reboot cycle. What's the culprit?


19 months ago

Hey all. I'm scratching my head anxiously over this issue that's gotten progressively worse, and I'd love some help. Here's my parts list:

I built my PC back in December with the help of this wonderful community. I usually have it running through the night to play white noise and help me sleep. About a month ago I started getting BSOD with the frowny faces, and my PC would reboot. The stop codes were usually “memory management” or “page fault in nonpaged area”. I didn’t do anything about it at the time, stupid me.

They started getting more frequent, and the BSOD wouldn’t force a reboot anymore so I’d have to power off manually. I even started having trouble getting things like the monitor display and keyboard to work. I looked into how to fix the “page fault” error and ran some scans in the command prompt. I wasn’t able to complete them before getting another BSOD with the “memory management” stop code. Again, I had to manually reboot. I discovered the display wouldn’t come on unless I used my graphics card’s HDMI or DVI ports. I tried booting in Safe Mode and it still gave the error after a while.

I was then unable to consistently get any display. Tried DVI and VGA, didn’t work. Tried DVI port from the GPU, only worked sometimes. Tried my TV with HDMI, only worked sometimes. PC was powering on, just no display. I opened the case up and reseated the RAM and GPU. A bit dusty inside, so I blew on it (bad idea, I know). Took it to Geek Squad and they were able to have it run through a diagnostic test, but the BSOD persisted.

I was about to power it on today to try some of the things mentioned here, like updating BIOS and Windows updates and to back up my files on a flash drive, but now it won't even stay on. It powers on for about 30 seconds without display, then shuts down (power light off, fans stop spinning). It just gets stuck in a rebooting cycle until I hold power to shut down. At first I was thinking if any hardware was the culprit, it'd be the motherboard. Now I don't know at all. Could it be the power supply? Should I try reseating the RAM again? Taking a can of compressed air to the inside? Resetting all connections to the mobo? Any help would be greatly appreciated!

It's gone too far, too easily diagnose.

Disconnect the HDD, see if it will POST and stay on.

Is your build equipped with a Motherboard internal speaker to monitor POST beep codes?

Looks like this, see link below.

Try a hard reset, remove the AC power cord and hold down the reset button for 30 seconds.

Plug power cord back in and restart, will it POST and stay running?

If not, unplug power cord and remove all but one stick of ram.

At this point, keep unplugging power cord, moving Ram stick to different slots, plug power cord in and try to POST and stay running. Continue process until all Ram sticks are tested in all Ram slots.

At any point, did it POST and remain running?

Next, would be removing the Graphics Card, restart and see if you still have video, if not, this is where the Motherboard Internal speaker comes in to monitor Post beeps. Check to see if fans remain spinning. Give 5 minutes to make sure it stays running.

If not, remove all wires which are connected to the Motherboard from front case. Take a flat-headed screwdriver and short across the power switch pins on the Motherboard to start Computer. Note: Check to see if your Motherboard is equipped with a power button. If so, you will not have to short power switch pin on Motherboard.

Does it POST and stay running?

I'll stop here and see where you're at before continuing to troubleshoot.

Thanks so much for the help! Turns out I was dumb and didn't make sure the RAM was in ALL the way when I reseated it. Now it will POST and I can get into BIOS and all that good stuff. I still only get a display using graphics card's DVI and HDMI ports, but not 100% of the time. My PC also seems to take a good minute or two to give a display and load Windows after I power on. And of course, still getting BSODs with "page fault in nonpaged area" and "memory management". I was able to get Windows updates and update my BIOS to the latest version. I did the trick with holding down reset for 30 seconds with system unplugged. Still no luck. Would you suggest I back up my files and do a fresh install of Windows?

Hello, sorry to hear your still having issues with your PC.

OK, let's review what we done, so far, to troubleshoot the "BSODs" and continuous "Reboot Loop"

I'm going to assume, you've completed all the steps I suggested earlier.

So far, you found an unseated stick of Ram and re-seated it. From what I'm understanding here, you're no longer experiencing constant reboots after re-seating the Ram. Although, you're still getting frequent BSODs.

The BSODs messages are, "page fault in nonpaged area" and "memory management".

OK, here's where I'd like to go from here.

Instead of me spending all kinds of time typing out fixes, I'm going to instead provide web links to various tutorials to attempt to repair the PC.

After you complete these steps get back to me with detailed results. (Important)

At this point, I think it's too early to reinstall Windows because if the issue is"Hardware" related, the system could crash in the middle of reinstalling Windows... not good.

And if that were to happened, we'd have a new problem to deal with.

So, here are the link for steps to troubleshoot and try to eliminate what might be causing you BSODs.

The Windows 10 error Page Fault In Nonpaged Area usually results in a BSOD and can be quite frustrating to troubleshoot. Here's how to fix it. ... The root cause can be software or hardware, often an aborted Windows update or driver conflict from the software side or faulty RAM on the hardware side.,36234.html

Here visually check the steps you're taken and make a check list of what you completed, so far.

Some comments about causes for BSODs.

Make sure you keep details notes, so we don't lose track of where we are! You can summarize your responses.

OK, I'll stop here. Get back to me after you've completed all these steps.

Hey, sorry for the late reply. I haven't finished all the steps in the POST/boot/no video guide yet, but I didn't want you to think I've been ignoring your advice. I've just been super busy with packing and cleaning for my move to a new apartment (such an inopportune time for this kind of thing to happen, I know >_>). I essentially haven't gotten past Step 8 yet, but I feel the CPU plastic guard is removed (Step 9) since my PC has worked fine for half a year. Here's what I've done so far:

Previously, I updated my BIOS using instant flash to the latest version. It did not crash during the update. For now, I'm still only able to get a display using the DVI and HDMI ports on the graphics card

I shut down the PC again

I opened the case and unplugged/reconnected the CPU power connector and CPU fan connector

I double checked the manual to ensure my dual channel (4x2) RAM were in the right slots

I powered the PC on. Got it to display the “BIOS home page” (F11 to enter BIOS, F2 to run UEFI setup utility, etc). The screen remained there, either frozen or unable to continue, so I powered off manually

Opened the case and sprayed compressed air to clean out dust (wasn’t that dusty to begin with but I bought the can for that reason)

Powered PC on and stuck on BIOS home page again. Powered off manually

I noted there are 9 standoffs screwed into the case behind the motherboard but only 8 screws in on the front (I know a step is to make sure all screws match the standoffs but I’m not quite ready or confident in dismantling all the connections)

I reseated the graphics card and ensured all power connections are good

I took out one of my RAM sticks (had them in A2 and B2) and placed the other single stick in A1 (first slot closest to CPU)

Powered on, got through POST! Windows booted up! Logged in. All files intact. Showed 4GB memory working in task manager. Ethernet not plugged in at the moment. Opened a few PDFs and Microsoft Word. BSOD crash happened with stop code Memory Management (Ugh!)

Previously, these BSOD crashes would seemingly keep the PC on and I didn’t hear the noises of a reboot. This time, the PC rebooted as you would expect.

I tried logging in when Windows came up. Tried to load desktop, but another BSOD. This time, a new stop code “Bad Pool Header” and subsequent reboot. Tried logging into Windows again, and another BSOD with “Page Fault in Nonpaged Area”

This time around, after the reboot I got this page. Instead of clicking “restart my PC”, I powered off manually

I put the same RAM stick in A2 and got BSOD (memory_management) and subsequent reboot when trying to log in to Windows. Same thing happened with the RAM in B1. When I put the stick in B2, I was able to log in to Windows and get to my desktop. I have Steam and Spotify set to autoload. I canceled the autoload of Steam, and I got an error for Spotify saying it was likely corrupted by a virus. Before being able to do anything else, I got BSOD with “DRIVER_IRQL_NOT_LESS_OR_EQUAL” (4th unique stop code, ugh).

Upon reboot, I went into the BIOS and was able to check everything without any issues or crashes. With the BIOS at its latest version now, I’m not sure what to check here. CPU/mobo temps, Vcore voltage, and fan speeds are all normal. I stayed in the BIOS for about 15 minutes. Upon exiting the BIOS and logging in to Windows, BSOD with memory_management before getting to desktop.

Took out the RAM and tried the other RAM stick in A1 slot. Windows booted up, saying “automatic repair”, then “diagnosing your PC”, then the message “Automatic Repair couldn’t repair your PC”. I was able to shut down or see advanced options like “Go back to previous version”, “System image recovery” or “Startup settings”. I chose to shut down the PC using the option on the screen. What I saw is pictured here.

Booted up w/RAM in A2. Got into Windows to desktop and disabled automatic startup for Steam and Spotify. Attempted to use Blue Screen troubleshooting pack from the Control Panel but it found nothing. Did a few more things like opened multiple PDFs, Word docs,, and played a game of Solitaire (I suck at Solitaire). No BSOD. (I shut down through the start menu. I will attempt to connect to Internet tomorrow and stay online with it).

My question for now is do you think it's worth unseating my motherboard to check the standoffs and make sure they all align with and match the screws on the front? Would I have to disconnect everything from it before I take out the screws on the front and lift it from my case?
