Hi,
I got GV N970IXOC 4GD (gtx 970) last week, installed it on my computer and it worked fine up until today :
turned on my computer and there was no signal to my monitor, although the fan is spinning. I also noticed that the fan was making noticeably more noise than it did before. I tried using the DVI port that is on my motherboard (and therefor using the on board intel graphics card) and i had a normal output to my monitor. I also tried using an hmdi cable to connect my graphics card to my monitor, with no results.
My motherboard is a Gigabyte B85M-HD3, running an intel i5.
Nothing could have happened in between today and my last use of my computer (2 days ago), since I was not at home, and nobody else was either.
If anyone has any ideas, I appriciate the help, and am all ears.
