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.
