i just found out that my powersupply is is a 350 watt power supply and my card that i got requires a minimum of 450 wat power supply could this have anything to do with my problem which is that when i put the new card in nothing shows up on the screen the screen is just in standby however the fan is spinning and the old card does work. i just wanted to know if that is for sure the problem or if that is not a symptom of to low of a powersupply.
 
that is most likely the problem I had the same exact problem but with a 6800 GT I messaged some people on a forum just like this and it turned out I had messaged this same problem with the monitor problem and they said get a 500 watter PSU and it worked Perfect.so yea and definately the 7900 is an extremely powerful card and 350 aint ****!
