Apon clean install....

Ok it starts out, i run a fresh install of windows, my screen is normal, i then install windows fine, I install all Intel drivers network drivers, and everything goes according to plan , then i FN F7 to switch, it restarts, and picture on the screen is fuzzy and snowy, when i FN F7 and use the 680m its fine, but when I FN F7 to run HD4000 picture is fuzzy and snowy, i've run diagnostics, everything checks out , just have no idea why it would be snowy and fuzzy just running off of the hd4000

any info would be a big help

thx

 

Maybe try installing the HD4000 driver when it is active (fuzzy)?

 

yeah tried that stays fuzzy

 

Doh! That's me out of ideas - sorry

Is it the same at any resolution/refresh rate?

 

Sorry Double Post

 

Hmmm, you installing which drivers? I know windows updates always rolls back the intel drivers for me.

Fuzzy in what way, a picture might help

 

can you take a screen shot and post it? If it's fuzzy and snowy to us, then it's a software issue with windows, or a hardware issue within the iGPU. If it's not, then it's something within your display which isn't working correctly with the iGPU.

 

screen shots come back clean, no snowiness in them , i had a 660m in this thing upgraded to a 680m , had the lcd replaced already once and its still doing it even upgraded from a 3610qm to a 3920xm and it still does it when i am on the hd4000 graphics and not the 680m.... weird

 

Can you try an external monitor while only the intel card is enabled? Does that also happen in safe mode?

 

It still is snowy in safe mode and the external monitor shows no problems whatsoever, and like i have said i sent this thing in to alienware to fix a seven beep problem, got it back from them working but this was the first time i noticed this problem. I had them remote diagnose, they deemed the lcd was faulty, and they had a tech from alienware come to my house repair and replace the monitor once about a month ago. I have also upgraded from a 660m to a 680m and upgraded the processor from 3610qm to 3920xm and is still doing this..

I've tried different drivers.
I've tried fresh reboot- now with this everything is fine till i load the hd graphics driver and do a fn f7 reboot .......then snowy

i can fn f7 running off of the nvidia 680m , and everything is fine

 

Have you tried clearing the CMOS? Need to do it the hard way. Not resetting to defaults in the BIOS.

 

just tryed that but still nothing still snowy in the hd4000 fn f7 side

but thanks for the resetting process haha:thumbsup:

in bios it says raid mode i have 2 ssds raid 0

 

That is weird. Given what you've said, the problem definitely lies with the LCD, or its settings with the HD4000. I would say try playing around with the LCD settings in the Intel HD graphics control panel. Change one thing at a time (like refresh rate) and apply. The idea is to see if something within the iGPU's default screen settings is conflicting with the LCD's display limitations.

 

tried all that aswell nothing changed ...

 

Do you still have the original CPU? If you do it might be worth swapping it to prove out the HD4000?

 

it was doing it with the original cpu and continued after i upgraded to the 3920x, then i did a clean install and it was gone till i installed all the Intel drivers and could use the fn f7 utillity , then it was Christmas on my screen again

 

Oh well, just a thought

Have you tried to remove the device completely from device manager and select to also delete the driver software. Restart and windows should use one downloaded from windows update. Grabbing at straws here!

 

yeah just gave it a shot , no go thanks for your input its worth trying everything !! anyone got a pick axe? I wish the aliens would come and aubduct thier computer back :thumbsup:

 

OK, now it gets desperate! Remove the 680 completely and see what happens. Will get rid of any optimus type problem. V weird that an external monitor is fine and the panel has been replaced

 

I am almost thinking there is possibly something wrong with the LCD panel or the LVDS cable. Removing the 680M completely to see if it changes something is a good suggestion. You have the ordinary 60Hz display and not the 120Hz 3D-capable display, correct?

This one is a just a stab in the dark, but what thermal paste did you use? If it was a conductive paste, I am wondering is some got on traces or the tiny circuitry on the CPU die and maybe that is only affecting the integrated graphics part of the CPU.

 

This one has got me stumped. The fact that it does not show in screenshots points to hardware but why OK on the 680m? Think Mr. Fox could be onto something with the cable IF each GPU output is directly wired through it, which it probably is since the 120hz panel plugs into a different place and does not have the HD4000 output at all?

 

I just don't see that happening. Mainly because I can't see any company producing an electrically conductive thermal paste. That'd be like using gasoline for an oxygen gauge lubricant.



Second, the processor graphics is integrated into the die, and the entire die shield is bonded to the CPU interposer for a permanent bond. Maybe one CPU could have had it fail, but two?

OP, Something you said doesn't jive right with me. You said you installed the Nvidia GPU first, then the Intel graphics, yes? According to the clean install guide ( http://forum.notebookreview.com/ali...er-install-order-guide-alienware-systems.html), you should have done it the other way around. And also, you should use the stock Dell HD400 and 680m drivers to begin with just to get things going. If everything works about correctly, then you can update the Nvidia and Intel drivers.

PS: Fox, can we get the http://forum.notebookreview.com/ali...er-install-order-guide-alienware-systems.html thread stickied so we don't have to search the parent forum for it?

What the heck is that? Mercury or something? It would depend on what metal they use and how much of it in the thermal paste.

So I rephrase, I don't think any company would purposefully make a thermal paste electrically conductive.

As for my oxygen and gas remark, I turn your attention to this video: http://www.alaska4x4network.com/grant/051124-OilAndOxygen.wmv

This is what happens when oil (and oil product) oxygen (gas or liquid), and a little bit of pressure create...
