Weird problem with brand new GPU

Hello guys this is my 1st post to this forum.

Today i have purchased a new graphic card ASUS GTX 770 2GB DDR5 DC II OC
after installing this card i was amazed with its performance played several games ex.farcry3,crysis 3, tomb raider, metro last light was enjoying thoroughly.
but when starting sleeping dogs weird thing happened while double clicking the game icon my display went out.
after that i reset my pc and went up to starting screen then sudden blackout BAM.... no display but the CPU was running.
after that resetted my pc again now there was no display from the beginning.
thn my card has got two dvi ports and i think two hdmi....connected to another dvi port and everything was ok since then but unable to play sleeping dogs while other games are working fine..

so is there anything wrong with my card or its just the drivers
my specs are:

1.ASUS GTX 770 2GB DDR5 DC II OC (nvidia driver 320.49-desktop-win8-win7-winvista-32bit-english-whql)
2.asus mobo p8p67 pro
3.corsair vengeance 8gb ddr 3
4.corsair 850 watts smps core i7 2600k

    It's the GPU or PSU... download speedfan and monitor your Voltage if the 12 volt rail is good then most likely it a new defective GPU.

    thanks for the quick reply i will definitely do that and reply.
  2. Every game was working fine except sleeping dogs, now both my DVI ports were working fine.

  3. I had a similar problem with one of my HD 7870XTs when I crossfired them. It was a bad card.
