Win 10 lock-up problem

Hi Harry,

Thank you for contacting Microsoft Community.

In order to troubleshoot the issue, I would suggest you to try the following steps and check if the issue persists.

Method 1: To diagnose whether this issue occurs in “Safe Mode”, let’s reboot the computer in safe mode with networking and check if the issue appears there as well.

Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This helps us in identifying whether the issue is due to some third party programs conflict. The word Safe mode appear in the concern of your monitor to identify which windows mode you are using.

Follow the steps given below and check if that helps.

1. Unplug external devices connected to the computer expect keyboard and mouse.

2.  From login screen, press Shift key and click on the Power button and click restart to enter Advanced Boot Options.

3. In this page select troubleshoot option.

4. And click on Advance option.

5. Select Startup setting from advance option.

6. Here you will find Restart button, just click on it.

7. In new windows press F5 to login with safe mode with networking.

If the issue does not exist, try to clean boot the system.

Method 2: Perform Clean Boot.

Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. Check this issue in clean boot state.

1. Press Windows key + X key. And select Run.
2. Type msconfig in the Run box and hit Enter.
3. On the Services tab of the System Configuration dialog box, tap or click to select the Hide all Microsoft services check box, and then tap or click Disable all.
4. On the Startup tab of the System Configuration dialog box, tap or click Open Task Manager.
5. On the Startup tab in Task Manager, for each startup item, select the item and then click Disable.
6. Close Task Manager.
7. On the Startup tab of the System Configuration dialog box, tap or click OK, and then restart the computer.

Thank you for your response but still no joy. PC still freezes randomly especially soon after startup in AM and then usually after a hard restart, it behaves the rest of the day. I tried everything you suggested including Safe Mode for a while and the PC did not freeze but I could not get on the internet.

I tried Clean Boot and disabled everything in Startup. Tried sfc /scannow and DISM with no problems found. Ran MalwareBytes and just a few PUPS removed so I don't think it's a virus issue.

Now a new problem happens this AM. Started PC and after getting to the Desktop, I see a blue screen reporting the unexpected_kernal_mode_trap error. After several restarts and a failed MS attempt to diagnose and repair, I finally was able to get WIn10 started and write this report.  

Right now, there are no external devices connected except wireless printer and internet and everything in StartUp is disabled.

My PC is a Dell XPS 8300 bought new in 2012 with Win7. It came with NVIDIA GeForce GT545 driver updated to 11/5/15 version. That is the only driver change I made. Dell won't support PC anymore because it now has Win10. So I upgraded to Win10 based on MS recommendation and assurance that my PC is compatible and Dell won't support it anymore. MS needs to come up with a fix for this.  

Hi,

Thank you for the update.

Please refer to the answer given by Giridhar J dated August 12, 2015 and check if the unexpected_kernal_mode_trap error persists.

Please let us know if the issue got resolved or you need any further assistance.

I'm beginning to feel sorry for MS Windows 10 support engineers. After reading so many reports here, it appears that Win10 is a disaster in the making. After my "upgrade" from 7 to 10, I started getting the lock-up issue. I've tried every test and diagnostic I know including an hour long Dell diagnostic run yesterday that found nothing wrong with the machine.

And now I'm getting a series of BSODs. They are the unexpected_kernel_mode_trap a couple of days ago, then yesterday a memory_management BSOD after starting Photoshop and today the bad-pool_caller screen out of nowhere. All of which just lead to endless hours of fishing expeditions. I've tried clean boots and disabled everything in Start Up. I do have a bunch of files in windows/minidump but can't read them.   

I would roll-back Win 10 to 7 if I were not afraid of the consequences that others have reported. If Win10 were a car, it would be eligible for a Lemon Law claim.
