Hi,
I have an Alienware M9700. I shut it down one night and everthing had been working perfectly upto that point, however when I powered it on the following morning I hear the windows startup sound but know graphics on the display. This is the same when an external monitor is connected. I have replaced the GPU but its still the same. Is there anything else I need to look at, Mainboard etc? thank you

I have same laptop, same problem. The GPU is defective from Nvidia.(check lawsuit and affected gpus cc2006-2009)Reflow did not work for long, changing gpu M8700GT could lead to problem resurfaceing. Best solution was to use hot(I used edge just to cover chip) iron-cotton lvl, on gpu silicone chip. Left it for about 10m and then let it cool.(worked great after.) It will not affect different gpu parts like a reflow.(will not affect gpu as its under 200c). Weight of the iron fixes joints problems and internal chip silicone problems for a while.No need to press on Iron. You can complement gpu copper cooling with a copper-plait to keep everything thight.
这个答案有帮助吗？

Hi @chewie814 ,

Hi @chewie814 ,
Don't know your laptop but looking at the specs it says it has dual video cards SLi enabled.
Not sure what you meant when you said that you replaced the GPU but did you try removing one or then the other video card to see if you get an image at all with only one card in?

Hi,
I've tried a variety of combinations. I'd ordered a slave 8700M in order to SLI the replacement card. So I've got 4 cards 2x Nvidia geforce go 7950 gtx (1 master and 1 slave), and 2x Nvidia geforce 8700m ( 1 master and 1 slave) the 2 7950x where creating display artifacts ( scrambled boot screen messages and blue/yellow Mark's on screen). Bought a 2nd m9700, planning to make 1 out of 2. So as my original m9700 had a 1920x1200 display I swapped that on the new m9700 and swapped my keyboard aswell as a few keys didn't work, swapped hard drives as mine was running in RAID0. Than after about a week the display went blank. Swapped everything back over including 8700m gpu. Still no display, next step when I'm back at work next week is to reinstall the 7950 HTC cards (master first) to see if the display returns in any form. I've also tried the 'new' working 8700m slave card on it's own. No change
Thank you again for your help

Hi @chewie814 ,
Really bad idea but have you done a BIOS reset?
i.e. remove AC power, disconnect main battery, disconnect CMOS battery, press Power button for 20 seconds , reconnect everything and turn on.
Apologies if you know all this already.
