Had a problem with the computer going blue screen of death on reboot on a system that worked fine for over a year. I was finally able to get in on a safe mode after rebooting several times and just got lucky more then anything. I noticed that even on safe mode the graphics were old CGA type (purple/violet type action). The sizes were totally off.
This lead me to believe that I had a video card problem. I had an EVGA GeForce 670GTX (2 6pin power connector required). I have a spare machine with an older card that only used one 6pin a GeForce GTS250. I stuck that into my rig and everything works fine after driver changes etc. In the process I reinstalled windows and have a very basic setup as far as programs go (think 1 game email client MS office and that's about it).
I went shopping for a new card and decided on the Gigabyte GV-N960WF2OC-2GD WINDFORCE 2X Gaming Graphics Card. This card uses 2 6pins like the previous GTX 670 I had in the system. I popped it in thinking that ok should be smooth sailing... Well the new card started performing similar (constant self reboot on startup) as the previous 670 did. I now have the older card back in the machine and not sure where to go from here.
I am not sure what's happening as on boot up I do see the Gigabyte logo with the new card 960card and its in a higher resolution as the graphics are tighter and smaller on the screen. This tells me that the card is working the way it should (so to speak). This opening bios screen lasts a long time then it drops to load windows. From there I either get a quick flash of a BSOD (to quick to see what's going on before it recycles or it goes directly to a black screen with cursor in the top left corner and eventually will try to reboot after a lot of grinding and moaning.
I was thinking it was the 6 pin power connector but it doesn't matter which one I use on the older 670 the card works so assuming I am getting the correct power to the video card. Windows has already been reinstalled with very minimal programs so ruling out that.
I do have a 1000W PS which is more then adequate to handle the load of 400W that the card needs.
Any Advice as I am coming up with nothing here and my wife wants her card back in the older machine
I digress but any suggestions would be appreciated.
My System specs are as follows
Running Win7 Ultimate close if not totally up to date
Motherboard -Gigabyte GI Assassin 2 X79 rev1.0 with a intel i7 -3820 CPU running at 3.6Ghz
16 Gig Mem total on 4 x 4Gig sticks cant remember type or speed think corsair but would have to pull one out to check if it becomes an issue I will
PS- is Coolermaster Silent Pro Gold 1000Watt
HD is Vertex4 25SAT3- 256Gig
Everything works fine with the older card just when I stick in the new 960 it chokes. Wish I had the older 670GTX still but threw it out thinking that was the problem.
