Recently did a small upgrade and purchased the Gainward GTX295. With this i bought a Corsair 750w PSU to power it.
The physical installation all went fine, up until the boot up.
The computer powers up, all fans and lights inside the case spin and light up correctly (including the GPU fans and light). The computer beeps once, just as it does normally, but no output goes to the monitor. Nothing at all.
I have tried changing the port where monitor plugs in to both of the ones on the gpu, including the mobo onboard gpu port, no difference. The monitor works perfectly well, have plugged it into laptop and the system still works fine with old GPU. The new PSU works fine as it is now running the old GPU and letting me on here.
I have tried going into the bios to change the boot up video card input from AUTO to PCI to PCI-e and onboard. Each time i have booted up with the new GPU in and tried to plug monitor into each port. Not work.
If anyone has any suggestions about what could be wrong please help out, it would be much appreciated as the joy of the new GPU and the online game i play is getting ruined! You know how it is when you are all excited about new gadgets!
Thanks for reading and your help is very much appreciated!
Did you plug in the small square 4pin power connector to the mother board..... up near the processor ? And are there any 4pin molex connectors on the mother board itself ? And while you were providing power to all your hardware did you accidentally jar loose any other connectors.... on the HD, etc.

I know it sounds crazy but...
Ram issue? See what happens with just one stick of ram in.
Is the 295 powered up fully.....have u connected both 8 pin and 6 pin connectors???....if u can then boot up with CD and install a new OS.....since u said u can use the bios....its more likely a software issue....this may solve the issue....since the previous OS may conflict with the new hardware and may not boot.....
Reset the CMOS first. If that doesn't work, do a repair install so you don't have to lose everything on your machine. Many times, an OS will flip out with a major hardware change, and contrary to what you may think, adding a GTX295 is a major hardware change.
I have the same problem...but my PC when i press the power button it makes a piu piu piu sound and then nothing..and yes..no video output in my lcd.....and i think the gtx 295 is the problem...it`s not working
