have a gigabyte gtx 770sli gpu in a gigabyte ga-z87-d3h mother board, just keeps rebooting after loading the video drivers for the card. system is win 7, 8 gig ram, i5 processor. All bios and drivers are the latest. If I remove the driver for the video card the system will boot and run. when it does boot up with the driver installed you can see it glitch, like its loading up the gpu , then it reboots.

I did notice on the motherboard it has crossfire connectors. the 770 is an sli board, is this the problem? only running one board. oh the PS is a corsair 600 watt.

the card is in the pcie 16 slot but have tried it in the othe pci slot.

Would appreciate any advice/help on this thanks.

well the ctx 770 take a max of 193 watts at idle its 120 watts. the website to calculate power usage did not work for me. But I'll see if I can borrow a big supply. Yes this is a new build.
