Sounds promising.. Your idea of applying more voltage to the new sticks might be a good one and I have thought of mentioning it in the past but usually unless your stressing sticks there's normally no need. Give it a try Fil you never know.... The good news is that we/you are hopefully on the right track at last and I'm so glad you had that old RAM lying around. As for the power situation, well it seems that's been cleared up by the old RAM too as your machine has been starting as you wanted it to (via the keyboard) so I guess we can put that on the back burner. Please keep me updated Fil and good job!
