Windows 10: My windows pc keeps freezing 2 minutes after startup

I hope someone can help me with some problems I have with my windows PC. It keeps freezing after startup and I have been trying to find out what it is but nothing works.

So what happens is the following: whenever I start my pc it does okay, untill I load in some programs (not really heavy programs, just things like FireFox, sublime text editor, task manager). After loading the programs it tends to freeze and it won't unfreeze, which makes me force a restart. It mostly happens just 1 or 2 times in the morning and then proceeds to do fine the rest of the day without any freezes.

Some important facts:

- I think my CPU usage is at 100% while the freezes happen, temperature is around 40-50 degrees Celsius after startup

- About 2 months ago it started with a message showing up that windows kernel mode driver was crashing (I still used windows 8 back then), nowadays I do not get this message anymore (I upgraded to windows 10) but it still freezes the same way

- Specs: Intel i5 4460 @ 3.2Ghz quadcore / 8gb RAM / 125gbSSD (with windows installed on it) / 1tb HDD / GeForce 760 / Gigabyte Z97P-D3 motherboard

- Audio as well as video output will freeze

- I already tried scanning all hardware and software, already installed a fresh copy of windows, already applied new cooling paste. Malwarebytes, sfc scannow, other antiviruses etc all give nothing.


I have built this pc myself and have never had any problems with it untill 2 months ago, I know quite a lot about pc's and hardware but this seems to be something out of my reach, and that's why I am asking here now. Thanks in advance for the help!

Windows 10 freezes for 2 minutes after startup

Hello,

My Windows 10 freezes not directly at startup, but after it. I start my computer up, I log in with password, and then I get on the desktop. I can open anything, but after 1 minute my computer instantly freezes. I can still move my mouse around, but can't
select anything. This problem occured today, but I didn't really install anything vital yesterday, except for a folder for a game inside my localappdata. I doubt that's the thing that is freezing my pc. So yeah, after 1 min of being logged in my screen freezes,
and I can only move mouse and nothing else. This freeze lasts for about 1-2 minutes, and then I can completely use the computer again. So I can still use my computer, it's just annoying that I have to wait for my computer to unfreeze. What can I do to help
this problem? I'd like to try some things before eventually returning this pc to the company that built it.

Thanks in advance for anyone who answers.
