Sorry, this is probably confusing but I'm including all the details to help speed things up, I've got computer specs at the end. The short version is I've tried 2 different Galaxy GTX 560 Ti cards and both are unable to do anything that requires more complex graphics than a windows display.
The long version:
Several weeks bought a Galaxy GTX 560 ti to replace my aging EVGA GTX 260. When the new card came I removed the old card and installed the new card. (I now understand that meant that I missed a step), and windows would load but when I tried any games it would just sit there on a black screen and/or lock up the computer. If I tried activating my second monitor both screens turned black. I attached the two extra PSU cables to the card. I tried using the older version of the drivers that came with the card, the current Nvidia drivers and a beta version of the drivers, as well as the windows vista drivers for it, to no avail. Same problem no matter what.
I upgraded my PSU from an Apevia 750W, which didn't have enough current on the 12v rail (but still powered the gtx 260 which had greater power demands) to a Thermaltake 850W PSU with more than enough current. It didn't make a difference.
Galaxy's "24/7" customer support suggest that I update my BIOS (I was using the most up to date one available) and plug in the power cables (I'm not that dumb, I did that ). Nothing helped so I RMA'd the card with Newegg and today the replacement came.
This time I removed the GTX 260 from the device manager and then used DriverSweeper to remove all traces of the drivers. I also updated the motherboard's nforce drivers. However, it is doing the exact same thing. Windows loads ok, when I try and run a game it craps out. After that I have to use the reset button, and when it was back to windows the resolution was quite low, when I tried setting it back to the native resolution the computer locked up. This is the same behavior the first card exhibited.
I don't know what to do and am really frustrated since right now it looks like I just got a $250 paper weight. I've tried it with WoW, League of Legends and BC:2.
At this point I'll pretty much do anything to get this to work, but my preference is to not spend a ton of money replacing the rest of my computer's components.
