Following the R2D2 beeps of death

Hello
Following my last post " http://forum.notebookreview.com/threads/change-processor-alienware-17-r5.809409/", I ordered a processor, I mounted it, nothing wizard, but I still have the beep of death,
result hs motherboard
so, go with your help demonter to replace motherboard,
my question, have you somewhere how to disassemble the alienware 17 r5 or a job mode to disassemble and remount
once again desolate for my English
thank you all

 

7 beeps usually means CPU failure...are you sure that the new or used processor which u have bought and placed in you m17 r5's motherboard is properlly placed and tightened? and did you check your old processor and also new processor which u have bought in any other working laptop ? also check any bent pins of processor and let me know

 

For disassembly, hope this video will help you

 

Thank you for your help
I already change the CPU, well reassembled, and tight in his box, always the 7 beeps, but I have no other pc to test it, nor the old and the new
the disassembly happened without real problem, there, I wait a mother card in hope that it will work
if other ideas come to mind, I'm interested
still sorry for my english
thank you

 

its ok dont be sorry for english ..not everyone is perfect in speaking english so dont think like that...well you need to first check your cpu from any laptop shop to make sure that ur old and new cpu is ok ....try booting without gpu and reset your bios completely

 

thank you for your comeback
I did not know that we could start an AW without CPU, by cons how to reset a bios? thank you

 

not cpu .. i said BOOT UR laptop without GPU(GRAPHICS CARD) if it is removable ..to reset the bios you need to remove a small coin sized cell and i would also suggest to remove rams and the battery of your laptop ...without plugging or battery or charger hold the power button(alienhead button) for atleast 10 seconds..this should reset the bios and then put everything back from where it was removed...this time try to boot without your graphics card if it is removable otherwise just ignore this step and do the rest

 

hellos
I did well what you told me, disassembling graphics card that is removable (NVIDIA GeForce GTX 860M graphics with 2GB GDDR5), remove the battery for reset bios, battery, etc ... still it's cursed beep, there I do not know what to do, besides order a mother card on auction sites, but I have to wait almost 1 month for the reception (China)
one of the participants who will recognize that I salute in passing, my advice on the choice of motherboard,
my model is a CN-041W46 VAS00 LA-9331P and used are sold at 199.88 USD
a new type CN-05RW0M Intel LA-9331P are sold for 240,00 USD,
I think if you agree with me that I order the one at 240.00 USD
if among you a person would have this kind of parts, sometimes that ..
thank you

 

A defective ram stick can also cause 7 beeps. Try booting with only a single one, testing each separately.

 

well that is sad...last try is to do what @t456 said above ... if still it gives 7 beeps error then just order a new motherboard

 

I had already tried this first, I started again to this day, always rd2d2 who answer me , maybe who says to me,
"see you at the cinema see the next star wars"
in short I will order a motherboard, and the delivery time is long so I'll come back to you for the future
in the meantime I thank all the team who helped me
thank you all

 

well best of luck !
