I'm getting long (greater than 1 minute--I'm used to about 10 seconds) boot times with a completely blank screen after installing my new card. No BIOS message or anything, then eventually Windows loads.
After booting, it seems to be working fine thus far. I flashed to the latest firmware from the forums here. I was initially crashing the drivers but I think that is because I didn't reboot after installing the drivers. Ran a few tests again and they aren't crashing.
It looks like this is a fairly common issue on forums but I didn't see any solutions.
GPU: EVGA GTX 970 SC ACX 2.0
Motherboard: Asus P8Z68-V Pro/Gen3 (latest BIOS)
CPU: Intel i5-2500k
RAM: 16GB DDR3 1600
Other PCIe Slot: Creative X-Fi Titanium HD sound card
Any thoughts? I'll also submit a support ticket.
