Computer locks up during the HP startup screen

[RedIce25]

Hi.

I bough an ASUS GeForce STRIX GTX 750Ti to use in my Pavilion P6- 2069sc but when i start the computer after installing my GPU the screen locks up on the blue HP start screen.

When i try to hit the esc key to enter BIOS or any other keys there just comes a beep from the machine.

There comes one long beep every 20 seconds or so from the computer.

When i use the integrated graphics everything works the way they should.

I already have upgraded the PSU from 300W to 550W

Because you computer was manufacturer Sept 2011, it has Legacy BIOS.  The newer UEFI vBIOS was initiated into HP units late 2012.  That said, you either stay with a Legacy BIOS GPU card, or select a Hybrid dual BIOS card.  The  GTX 660, or GTX 670, both of which are high-end Legacy card would be far superior to the GTX 750Ti.   All the current hype leans to a lesser quality card,  the GTX 750Ti, based on lower wattage and some offering a Hybrid BIOS via select manufacturer. The Asus might not be hybrid, as you can attest.

Based on your existing new PSU, (hopefully a quality unit), the GTX 660 would be good.  IMHO, an EVGA GTX 660 would be best based on your system PSU. Please call EVGA to re-verify a Legacy BIOS. 

PS<> I have EVGA GTX 660 and 670 in my Legacy BIOS towers.  I tried an ASUS, but it did not like an ASUS motherboard. Strange, but ASUS verify the fault was their own card. Cost  me a $50 return fee, so PLEASE verify with any manufcacturer.
