Hi there! Hope you're all well.

So yeah, as the title states:

  • Windows 10 Freezes about 1 minute after booting. It happens slowly; programs start up fine within the first 20 seconds, then it all grinds to a halt. If I leave it long enough it can say 'windows explorer has crashed' or even just cut to a black screen. It can also happen if I don't login immediately.
  • It is, however, completely fine in safe mode with networking (typing this from the comp atm).
  • I reformatted the computer as soon as this started happening. It was fine for a few hours, then started again.
  • I've tried booting with just one stick of RAM (tried each one), and I also took out the GPU, but the problem persists without these components.
  • I tried a windows resource protection scan - no integrity violations. I also tried checking the Event Viewer but I couldn't see any errors in either System or Applications. I also watched the task manager while this was happening - there were no crazy spikes in CPU or Memory usage or anything. Seemed normal.
  • I reformatted my comp a couple of months ago becuase I got a virus. Around the same time, I booted the comp up and it said my BIOS was corrupted - but it automattically restored a previous version and I haven't had the same problem since.
  • Around the same time (2 months ago) I installed a new SSD boot drive.

I've tried searching on google for similar threads pretty extensively, but while I can find some people with similar problems, they always seem to come up with a solution that doesn't apply to me, or the thread trails off...

I'd be super greatful if anyone could lend some insight into this!

SPECS:

Intel i5-4670K = CPU
Gigabyte Z87-D3HP = mobo
Samsung SSD 850 Evo = boot drive
NVIDIA GeForce GTX 970 = GPU
Corsair RM750 = PSU

Many thanks!

Does the computer freeze when doing a clean boot?

Run the computer for awhile in clean boot. If it runs without freezing then there is a conflict between services or startup items. Enable a few at a time and reboot until a freeze. This would narrow down what is causing the problem.

ugh THANKS SO MUCH this was a really helpful reply!

 

The computer boots fine with a clean boot. Crucially, it also works fine with just the graphics drivers, which is useful.

 

I don't have time to comb through and see what the actual source of the problem is right now -  but thankfully I can actually use my comp to work today (yesterday I was having to render animations on my laptop, which took about 4 times as long...)

 

I had kind of presumed the problem was a hardware defect, because the same problem happened both before and after a clean reformat. But I guess I must have reinstalled the program that was causing the problem? Perhaps it conflicts with a driver or a piece of hardware or something?

If you can operate normally using a clean boot then you are correct, there is a service or startup item that conflicts. You will need to narrow down which it could be. It may even be your Security Suite.

 

Another program that can help but takes a bit of a learning curve is process explorer. You could open it in normal mode and when the computer freezes look for a process that is using a lot of CPU.

 

When you have some time:

Another tool you can use is the Resource Monitor in Windows. In Resource Monitor click on the CPU tab. In the Processes pane look for a process that is consuming a lot of CPU and the Description. Check the box next to the process and in the Services pane you can see the service that is causing the CPU load.

Okay, well I had some time this evening so did a few things to make sure. I updated / flashed by BIOS and upated literally every driver I could think of. I then slowly booted with more startup things turned on - checking Resource Manager - but actually, the problem seems to be fixed (although for some reason it wouldn't allow me to re-enable 360 Total Security. I use Malwarebytes as well so I'm not that fussed).

 

But, it's made me reconsider how many things I allow to boot up with my PC anyway. I've trimmed the start-up applications to the bare minimum, in the hope to avoid anything like this happening again.

 

Thanks so much for your help!

Your Welcome, and thanks for the update. You can always uninstall 360 Total Security and reinstall. If you are using the paid version of Malwarebytes then I would not recommend using 360.
