YLOD sometimes. Sometimes when pressing the power and some in games

Yeah I don't really know how to write my title better. But yeah I have a PS3 k01 80GB that YLOD’s while using it, turning it on, turning it on then idling first the first icon on the XMB.

It did a lot more with the 80GB HDD. But I did upgrade the HDD. It DOES ylod less but it still does. In game (disk and digital), on the XMB, and on power on. What can fix it?. Do I need to buy a PSU?. It was a Gamestop Premium refurbished…

I didn't buy it with warrenty.

i bought it in December 2019 btw so returns are way past
