Hi , I'd like to ask for your help .
A few months ago I found out that I can have 2 video cards in the same PC . And I am talking about 2 different cards , not 2 the same cards (like in SLI) . I had asked here , on Tom's hardware :
http://www.tomshardware.co.uk/answers/id-3579412/cards-motherboard.html
I followed the the instructions and the 2 cards worked indeed .
So , back then in my PC I was using :
on Slot 1 : a GTX 580 , connected to the monitor via DVI-D
on Slot 2 : a GTX 1060 , connected to the monitor via D-SUB (plus a converter , but this is not the point) .
My monitor was an EIZO S1932 .
The reason I kept 2 cards , was in order to have one for the old WinXP (the GTX 580) and one for Win7 (GTX 1060) . I have separate hard disks for each of the OSs . (modern video cards like GTX 1060 are not supported with drivers for WinXP)
A few months later , I moved onto another monitor , and then the situation was this :
on Slot 1 : a GTX 580 , connected to the monitor via mini HDMI
on Slot 2 : a GTX 1060 , connected to the monitor via DisplayPort
My monitor became an ASUS PG248Q .
Practically , the only thing that changed (apart from the monitor) was the connecting cables towards the video cards .
Everything kept working fine , except that the new monitor can no longer automatically select my preferred cable and I have to manually set the monitor to either GisplayPort or HDMI (in order to use either the GTX 1060 or the GTX 580) .
However , today a problem appeared . I replaced the GTX 580 with a GTX 770 (I did this in order to have both cards with DisplayPort rather than HDMI) .
So now I have :
on Slot 1 : a GTX 770 , connected to the monitor via mini HDMI (or DIsplayPort)
on Slot 2 : a GTX 1060 , connected to the monitor via DisplayPort
My monitor remains an ASUS PG248Q .
And here's the problem :
I can still use the card on Slot 1 for connecting to WinXP (that is the GTX 770 , either through DisplayPort or HDMI) ,
but I can no longer connect with the card on Slot 2 (the GTX 1060) to Win7 ! ...
When ever I do this , the screen remains black ... I can see the PC loading up , but I get no image on the monitor .
I tried something else : I tried to connect to Win7 by using the card on Slot 1 (the GTX 770) , but although I did got into Win7 , the video card was not recognized . Win7 started automatically installing drivers from the web , but after a few seconds it stops and it says that it failed . So , through the GTX 770 I get into Win7 but the image is not a good one (probably on 60 Hz instead of 144) .
So , do you have any ideas about what might go wrong ?
I can only add 2 observations :
a) I put back the GTX 580 into slot 1 , and everything came back to normal as before (that is I can get into WInXP with GTX 580 and into Win7 through GTX 1060) .
b) I also tried installing a GTX 960 (in slot 1 , instead of the GTX 580 or GTX 770) , but I got exactly the same problem .
So it seems that except the combination of 580 and 1060 I can't use anything else ...
I am afraid that the problem is that after I put in the GTX 770 (in the place of the GRX 580 in slot 1) , now my PC on Win7 things that the video card I want to use is the one from slot 1 (that is the GTX 770) and that's why I can't see anything through the card from slot 2 (GTX 1060) . However I can't change to GTX 1060 , because if I use the GTX 770 the system denies me to use the GTX 1060 (in device manager the GTX 1060 is shown with a yellow exclamation mark) , while when connecting the monitor to the GTX 1060 I simply get black screen .
I have also thought to manually download the latest drivers for the GTX 770 (also contains the driver for 1060) and try to see if I can specify which of the two cards I want to use . However I am afraid to do that , because I might break up the combination of GTX 580 and GTX 1060 (because as I said , if I put back the GTX 580 , everything works fine again) .
