oK I think it is three rings because E 74 there a problem with the your GPU and go here and it will show it (
). Now the problem with the two red lights is a mystery to me. I don't really suggest doing is, as said about I found out you can resolder the GPU using heat gun and i found this
but the heat gun or overheated (i have done this and it worked (overheated)) is the only way i have found out to do it for free Tried to direct the air is the only way it might be more successful for heat gun
