So I just installed the MSI 990FXA-GD65 to replace my ASUS M4A88T-V EVO/USB3 due to the fact that the ASUS didn't accept SLI compatibilities. I installed the MSI mobo as I were to do with the ASUS with a few different plug-ins, but didn't have any issues through the process. I've added TWO Nvidia GeForce GTX 560 Ti with the SLI bridge. As soon as I turn on my computer my power supply's fan, CPU fan, 120 MM (1) fan and both Nvidia cards seem to be running, but no display.
Using strictly DVI. I just plugged my xbox 360 (VGA) using an adapter to DVI and it works fine. Monitor is fairly new... HP 2009. Purchased it in 2010. Maybe a little old, lol.
@ss202sl wouldn't it still show a display even if its low?
In this case ur monitor and cables are out of the equation.
The reason that i've asked to test out with the single card is due to the fact that ur PSU +12V rail might not have enough juice to handle both cards. Since single card won't work, it should be something else.
It is a bit tedious and troublesome but if you don't want to RMA ur mobo or the new card yet, u better use back the old board to test each graphic cards again to ensure it is the mobo problem and not the card problem.
I went to http://www.extreme.outervision.com/psucalculatorlite.js.... And the recommended PSU was was 528 and I have 600. I just remember my MSI motherboard is compatible with windows 7... I have widows 8...
Could this be the issue? My old motherboard was asus and I got this a year ago and it was still running fine with windows 8, but I was able to view both graphic cards but without the option to SLI.
I'm thinking its the motherboards fault here. Got it from tigerdirect while the box was OPEN... All fans seem to be running fine, but very quiet, no beeps to indicate the reason being. Can't even open up my Blu-Ray player. My ASUS motherboard was working perfectly fine three days ago, so I know it can't be the power supply, the vide cards, nor the monitor.
