BSODs randomly appearing

[Satansbraten]

Hello everyone,

first of all i want to thank anyone spending time with me solving this problem
Where do I start?
I encountered Bluescreens since I upgraded my gear a year ago. At first I thought I would get them solved by updating my local drivers ect. However by now I am almost certain that some of my hardware is damaged.

To the hard facts:
There are random BlueScreens appearing when gaming or even watching youtube videos. As well as some annoying pixel squares appear after some time of usage.
I cannot show you minidump files as oddly my windows does not save them.
However i read out my error files for you.

I cannot reproduce any bluescreen, however they seem to be more likely to occur when the PC is running for a longer time. As well as I discovered a lot of BSODs during the latest heat period here in Germany. This might sound odd but I am quite certain about this.
My suggestions are either a broken Graphics Card or Mainboard problems.
My power supply is by now at least 6 years old. Maybe that might be a problem as well.

I'd like to have your oppinion about the case and am looking forward to fixing these annoying BSODs.

Thank you for taking your time.

I had the pixel squares fixed as they were a product of some windows upadte, however they started appearing again when using firefox browser.
