So today I went out and got a Cool Master Extreme Plus 550watt PSU and a Gigabyte 5770 to put in my current computer which I've have for about 3 years. but when I put the power supply in and connected it all together and turned it on I was getting no power to my monitor at all, I've tried unplugging all the cords and reconnecting all the cords. also for some reason I don't belive that the card is getting sufficient power cause when I take off the power adapter from PSU to Graphics card the computer loads up like normal but still nothing from the monitor! Please help!
Btw the Motherboard is an Asus P5LP-LE
