Alienware M17x R3 Won’t Start - Tried R4 Parts

[ShadowMirror]

Hi guys,

 

One day my M17x R3 gave me 6 beeps.

It’s a 3D version. No onboard graphics. 

I got a “2D” M17x R4 with onboard graphics & used it to test. 

 

I replaced the Nvidia 560m with a 660m & the R3 now gave me 8 beeps instead of 6 beeps. 

Looks like the M17x R3 supports the 660m?

 

I put the 560m in the R4. It shows up in BIOS as Nvidia GFX. But in Device Manager it is just listed as VGA. In Properties it says “Error: Unable to start device” or something similar. Tried installing drivers from Nvidia and got the error message “Device not found.” or something similar. 

Does the M17x R4 support the 560m?

 

I bought a replacement 3D screen & the R3 still gave me 8 beeps. LP173WF2 (TP)(A1)

 

I tried connecting each of the two 3D screens to the R4 & both times got 8 beeps. 

Should the R4 support these screens? 

It has the 2D & 3D connectors on the motherboard.

:sigh:

 

Are 2D/3D parts interchangeable?

 

Any help would be appreciated!

 

Thanx
