Hello guys, I bought a brand new EVGA GTX650 on sale to replace my aging 4890 but I've run into a bit of a pickle...

Here's my system:
ASUS P6T Deluxe
i7
12GB RAM DDR3
1000w PSU
W7 x64
Monitor hooked up with DVI

Step by step I did to replace the card:
- Turn PC off and unplug everything.
- Open it up and remove old card.
- Plug in and install new card.
- Plug everything in and boot it up.

Here's the problem: The computer is booting up perfectly, and so is the card (the fan on the card spins). I can hear the Windows Logon, so everything is fine on that end, but there's nothing showing up on the monitor!!! I tried switching the cables, switching the ports but nothing! I have not touched the driver of the old card, because I assumed it would revert to Windows' default.

But there's a catch: I put the old card back in, and it's also booting up perfectly, everything works (the fan on the card spins) but I'm still not getting an image!

What have I done wrong? I don't suppose I've burned the cards, because both of their fans work when I installed them...

Please shine some light.

Thanks

How can I get into safe mode if there's no image on the monitor? =/ What is the default key?

I've been reading into it, I think I might have set off the Asus surge protecion... So I took off half the RAM, turned on and reset the mobo and booted without any USB or speaker (only left mouse and keyboard). It booted fine, now I'm going uninstall the old drivers and see what happens.
