Just to let everyone know, the reason behind my used parts choices is because of the budget builds the youtubers put out.
And yes, I have done a lot of researxh about used parts and know the risks of it. But yea, this is my 3rd pc build. The past 2 builts I have done from used parts were a success. Even earning some money flipping it around.
I have also researched a LOT, like all the threads relating to my problem.
As for the eletrical fault in my house, testing it in my grandma's place gives the same result.
As for the psu, when I got the pc working from restting the cmos 1 time, I did stress the pc enough to consume lots of watts and try making the psu crash but it did not. I know it is not a baseline to know if a psu is defevtive or not but hey, it kinda makes sense.
Yes, I know my problem. Some would say why not keep some parts from the past builds. Well, I needed some money for better parts so I ended up selling almost all of it.
You know, young mind, young thoughts, inexperienced decisions. Maybe some time in the future I will have enough money for them extras ya know!
