Windows 7: BCD boot error, can't boot from any device

13 May 2015   #11

windows 7 professionnal 64 bits

Hi again and thanks a lot for your help mate.

Concerning the 2 tutorials you linked above, they pretty much only talk about the windows repair thingy, but i can't access it, my computer fails before i can even access it.
Booting from install CD = unexpected i/o error

Booting from 2 different ssd (one brand new) or a classic hdd = error while attempting to read boot configuration.

I already have tester the RAM.
Stick 1 in any slot, no stick 2= error
Stick 2 in any slot, no stick 1 = error
Stick 1 slot 1 or 2, stick 2 slot 3 or 4 = error
Stick 2 in slot 1 or 2, stick 1 in slot 3 or 4 = error
Stick 1 slot 1, stick 2 slot 2 = error

Concerning the voltage, i don't have the multimeter right now but what i can see in the BIOS is :
CPU coré voltage : 1.144v
CPU i/o voltage 1.040v
GPU voltage : 0.112v (sounds rly low)
DRAM voltage : 3.296v
3.3v : 3.296v
5v : 5.045v
12v : 12.144v

You talked about UEFI, yes i can access some UEFI shell prompt but i have no idea what i can do in it.

Your DRAM voltage : 3.296v is reported way to high.
The highest ram voltage I have ever seen is 1.65 volts.

Your ram should have a sticker on the side of every module to give you the recommended max. volts.

Yeah definitely too much. Max I have seen is 2-2.1v for overclocked RAMs.

But it looks like a typo: the 3.3v (one line below) reading is the same.

Eww so sorry it's indeed a mistake from me .
It's actually 1.472v in the BIOS (vs 1.65v recommended)

Thanks for your replies Layback Bear, GokAy

Yes well if the volts are showing up as they are then the PSU is probably ok I do like to use a software program call HW Info to find it but it needs the machine running.

The GPU voltage does indeed look very low - when you get that meter try the volts at at the plug for it as well as the 24 pin plug as previously mentioned. I am asking because the meter cannot be wrong the info you are getting are from the system and even though probably right if the board is going south then it might well be the volts are not being shown properly.

So I am not reading it wrong you say you have errors in the RAM? if that is so then have you got some spare RAM sticks - even some older 1333 MHz ones would do just to test if the ones you have been using are no good. It would certainly pin it down to the memory for at least one thing, because to me as you have done exactly what I would (and the others) have suggested doing and each combo has thrown up errors??.

Yep any RAM set up leads to error, but the same error as usual so i can't say if the RAM is the cause.

I'll try to get the multimeter and another RAM stick ASAP

Its a pity you cannot get this machine to boot because a memtest is really what we need to do and I think getting that other stick is probably going to maybe show us what is going on. It really doesn't matter about the speed as I think that board said it supports 1066 and 1333 sticks, and they really are not that expensive these days (says me of course).

Of course if the new stick shows up errors it could then be the slots but perhaps it might be worth cleaning them first -
Now as for the slots to clean them use a strip of old credit card about 1/2 inch wide nip the corners off one end - preferably round them offhold a piece of thin lint free cloth over the end dab on some form of alcohol - isopropyl alcohol (what we swab the skin with before an injection) is good and GENTLY swipe along the slots.
This can also be done for the GPU slot/s and also the contacts of the sticks or cards - not the stick but some lint free cloth of course. See my pic for the sick but please be very gentle doing it if you are in any doubt - please ask before doing it but I use this all the time and have yet to damage anything.
