White screen on Imac 2011

[Alent]

Hello i’m new to working on computers but recently received this imac that had the problem of folder missing sign, I upgraded it to a ssd with High sierra os but then another problem occurred. It would load halfway and then stop and go white. I’ve researched for a while and tried many thing including resarts with safe mode and smc, but nothing worked. After a while miraculously it worked and for 2 days and now it is back to the problem again. I’ve tried many different things and now I don’t know what to do.

How did you upgrade and install the OS ?

Extended testing says the exact same thing

I manually downloaded it onto the ssd
