I have the GTX 750Ti SC installed (disabled old gpu driver), but when i booted the pc it gave three beeps, and two short beeps. This is my computer: http://www.computerstore.nl/product/140373/hp-pavilion-p7-1040nl.html I have upgraded the PSU to CX500M. The PSU works fine!
Notes:
Is the card dead or broken?
