Windows 10: Crashing on startup, tried to fix but still a problem

My problem starts yesterday when I booted up my laptop- I use a Lenovo G50-80 with Windows 10


At first everything seemed fine but a few minutes into using it it progressively got more and more slow, the thing turning to 'Not Responding', until it finally crashed. I had been using it pretty continuously for watching videos and downloading audios from a trusted site.


I managed to solve part of the problem last night by reloading Windows but today it's still freezing and crashing. I can't get past the password bit for Smart Mode I used all the known versions of passwords I usually use as well the usual pin I use to login. I even tried to start it with Smart Mode with Networking, and it still comes up with a password screen that I cannot get past.


The only thing I can think of is either I have some sort of virus or malware problem not that I'd be able to do a check for it given the amount of time it takes to crash, or a loading thing that comes from Steam, but it's never caused any problems before.....


I would appreciate any help you can give me.

Explorer Crash FIX!

Our old Dell Inspiron N5110 got this problem also.
Taskbar keeps refreshing. Thanks many hints from guys above pointed me the direction to fix it.
From Reliability History Monitor I found Explorer keeps crashing because of IDTNC64.CPL (type reliability history at Start)
1. the issue was from IDTNC64.cpl, the sound driver,
but I could not successfully to uninstall it from device manager nor control panel or rename the file or the folder.
2. uninstalled High Definition Audio Device few times, problem remain
3. tried to uninstall within Control Panel > Program file, yet Control Panel only open 2, 3 seconds then closed automatically.
4. finally solved Control Panel shut down problem by going to msconfig>services>and disable Windows Error Reporting Service. see below sequence:
Click window + R keys, type msconfig, Enter to open msconfig, click Services Tag and look for Windows Error Reporting Service. Unchecked it, then apply, ok then reboot system when it suggests.
5. After this, open Control Panel by clicking Start > type Control Panel. Then my Control Panel open and stay put, won't shut down by itself.
6. In Control Panel > Programs > I found IDT Audio and successfully to uninstall it.
7. No more taskbar refresh or Windows Explore shut down after uninstalled IDT and Sound still works great!!!
8. repeat step 4 to check Windows Error Reporting Services by clicking it. OK then follow system suggestion to reboot.
9. Control Panel still able to open and remain open. Sound still works and no more refresh.
10. From Reliability History monitor found no more Windows Explorer crashing.
I am happy and hope above steps help

UT3 Crash on startup

The usual startup crash I see on UT3 is on XP. Patching it with the latest DirectX update fixes it every time.
