Hi,
 
I recently upgraded from 1 GTX 680 to running Asus STRIX GTX 970 in SLI.
 
Now whenever I boot my system up I have a hard time obtaining video. When it boots, 9/10 times I have no video. I have to keep forcing power on/off til I get a video signal. I am very confused why only 10% of the time I boot my PC up that I will get a video signal. Any suggestions? I have my PC hooked up via Display Port to a 4K Samsung 28" monitor. I never had this problem before with my single GTX 680.
 
When I do get a video signal I get excellent benchmark scores and 100+ FPS in games so I know the cards are working correctly.
 
System:
 
i7 4790K
 
16GB RAM
 
Asus Max Hero VI Mobo
 
Asus STRIX GTX 970 in SLI
 
Samsung 840 Pro SSD
 
1000w Corsair PSU
 
Corsair Liquid CPU Cooler
 
System is connected to a 4K monitor via display port.

Re-seat the cards a few times, sometimes dust particles build up in open slots and cause connection problems.

 

Try 1 card at a time see if one of the cards causes the same issue by itself. Try each card in each slot by itself...

 

Test with a different power supply.

 

Those are the things I would try.
