Hi
I recently purchased a ASUS gtx770 for my custom pc. Before this I ran crossfire 5770s. I also purchased new ram. same clock rate as the old ram just a higher quantity (from 4gb to 8gb). Anyway I plugged in the new card started it up and uninstalled amd drivers. Installed new NVIDIA drivers and went right to BF4. Ran great for 5 minutes and then CRASH. I go to reboot and no signal from card to monitor, I tried to put one old 5770 back in and still no signal. I also noticed I have no communication from my keyboard or mouse. I triple checked everything is plugged in. My only thought at this point is the motherboard is fried. The computer boots right up but no signal to the monitor and no signal from anything in my integrated mobo usb slots. I have run out of ideas, do I need a new motherboard?
System Specifications:
ECS 1155 MOBO
Intel core i5 sandy bridge
g skill ram 8 gb 1600
rosewill 750w PSU
2 hitachi 7200 rpm hdds
