My PC freezes after a certain amount of time, usually between 1-3 hours.
It always happens while I watch Netflix and gamble at the same time.
I've already set it up from scratch.
The only old thing in the PC is my RAM and my SSD that Windows runs on, both about 4 years old. Could it be because of that?
The SSD breaks. Bake them at 200 degrees for 30 minutes and they'll be healthy again!
Once worked for me!
You should download the current windows update from the windows website
this is called october 2020
Is everything up to date, including my drivers.
Take a look in the task manager (tips in the search bar and press on expand task). All programs are displayed there with the respective load on the various components. If there's 90-100% permanently somewhere, your PC gives everything it can and at some point it can no longer. You could also switch your PC to maximum performance in the energy settings (search bar), this may help you. Otherwise just make Windows and driver updates
