How do I get my 30inch 3008wfp HD Dell to work with my new xfx295 Graphics card

[joe11112222002]

I have an i7 940 CPU with an Asus P6T Deluxe MoBo and 12GB of DDR3 1600MHz Ram my HD is a 1TB Samsung HD103UJ ATA Disk and my PSU is an OCZ 1010WATT unit, my new graphics card purchased yesterday 13/5/09 has an HDMI connection on it as does my Dell 3008WFP HD HIDEF Revison A02 Monitor, but when I try to use this connection type I cannot get the post to appear can anyone tell me why? also in games it sometimes reboots the PC and I have to start the game again, any Ideas on this!. Finaly I had an Nvidia gtx280 prior to installing this card and the graphics seem no better with my new card than they were with my gtx 280 is there something I have not done to make my new GTX295 work properly out of the box so to speak?. Any help or advice on these issues would be most welcome. Thanks.

I would try monitoring your GPU temps with GPU-Z or RivaTuner when the card is under full load to make sure that it is not overheating. The card should be getting enough power but make sure that you have all of the required connectors attached (it should have 2 or 3 power connectors attached to it).
