Random Crashes in games and programs?

[nmsxsu]

(I already posted this here but I'm reposting it because nothing worked and now my post is too far down and I'll delete it. The other guys suggested me to revert video card drivers and trying to run things on the onboard graphics but the first didn't work, and my programs and games won't even start with the onboard graphics)

 

I have a 6 years old prebuilt pc and in time I upgraded the ram from 8 to 16GB, the video card from a 2GB R9 to a 6GB GTX1060 and that old hdd with a samsung 860 evo 1TB. The only things I left are the PSU (550W), CPU (i74770k) and the Motherboard (I don't even know what mobo is this there's nothing written on it, I just know it's ASUS, like the whole PC). The PC was still running really good until a couple of weeks ago. It started to crash when I played heavier games like Shadow of the Tomb Raider or Wolfenstein Youngblood, and Also Apex Legends, just like that, randomly, without any errors. This was still acceptable since it was happening rarely and only on SP games (except Apex but I don't play that game so often) and my main game (Rainbow Six Siege) was working well as always. Now it crashes literally on EVERYTHING, even in stuff I need for work, like Photoshop and Illustrator. I get 3 to 6 crashes in every game session in any game I have, either SP and MP which is kind of frustrating (Apex is now giving me an error that says I PHYSICALLY removed my GPU). I did a couple of tests and checked the temps while games and programs are running, and everything is fine..I don't know what to do. I will buy a new system soon but I need to keep up with this one for at least a couple of months because I need more money. How can I solve this? Even if it's just a fix for the programs I need for work.

 

Things I already tried to do:

 

- Clean OS Reinstall

- Repairing programs

- Cleaning the system from dust

- Lowering GPU clock speed

- Using Linux installed in my old HDD, but even chrome is crashing there

I think the motherboard might have had it. If even Linux crashes in simple tasks, I think it is the MB that is done. It seems it can draw the power needed for installing the OS. Which will draw a decent amount of power.

Considering it is six years old and it was crap even when I bought it..
