Problem Upgrading GPU

[Mattington]

Today I picked up a new EVGA GTX 770 as an upgrade from a GT 640 video card. However, when I first installed the card I would get the error led on the MB. So I removed and reinstalled the 770 card and got it to boot up. But now there is a new problem, within seconds of getting into Windows 7 the screen turns blue (sometimes green) then it either flashes back to windows and I get a driver kernel recovery notification. However it just continues to flash until it goes black and the monitor goes into power save mode. I restarted back into safe mode, and updated the drivers (selected clean install). But on restart the problem still persists. Is this card DOA? Should I just return it to MemEx for a new one?

Thanks.

Ok, so I have the old GT 640 back in and everything is working as per normal now.

With the 770 I tried different power cables and everything, but couldn't get the card to show a screen more than 10 seconds when it got into windows.

Any thoughts on how I can get this card to work?

PC specs:
ASUS Z87-C MB
i7-4770k
16GB 1600 RAM (got the 3 above components put together at Memory Express)
EVGA 750B PSU
128GB SSD
3TB HD
BD drive

Thanks

Sounds like you just got a lemon of a card.

I would exchange it.

Possibly your power supply? The 770 is rated at 230W while the 640 is rated at only 65W.

Edit: Just saw you posted your power supply, which looks to be big enough. If you can, you can try measuring output voltages to make sure they are up to their rating. If not, it's easy enough to exchange the card as it is just as likely a lemon as psycnet said.

I exchanged the card, the new one has been in for 10min, and so far so good. Thanks for the help.
