I have a one year old refurbished HP m8100n, that has been working excellent with the stock 300w PSU. However, I'm going to upgrade from my current 8600GT to a 8800GT, and I fear my 300w PSU won't have enough juice.
So I've bought a 430w PSU that many has had their 8800GT powered with. No the new 430w PSU is not dead, it powers everything up when I boot up my system.
However, after the blue HP pavilion screen, instead of the usual Windows loading bar screen, a black screen with the following message appears: "Boot disk failure. Insert system disk and press ENTER."
So I figured it must be my cables not being plugged in all the way. I replugged the only four things that needed to be plugged, the 4-pin peripheral power connector to my hard drive, a 5-pin S-ATA connector to my hard drive, the 24-pin main connector*** to my mobo, and the 4-pin +12V power connector to my mobo. Still, that message showed up.
Then I thought it must be that my disk boot really failed. So I took off my 430w PSU and put back my old stock 300w PSU, plugged everything back in, and booted it up. Well what do you know? Everything ran fine again.
So here's what I eliminated as the problems:
-PSU NOT DEAD. I repeat, PSU NOT DEAD.
-Everything plugged in correctly.
-Boot disk is fine and intact. If only with the stock PSU.
And yes, both my CD / DVD drives are empty.
***There WAS however, one suspicious inconsistency. My mobo has a 24-pin slot, HOWEVER, my stock PSU has only 23-pins, with an empty pin in the middle of the 24 slots. The 430w PSU has all 24-pins filled. What is the meaning of this? Is this the cause of disk-boot failure?
