So i have been running with my Radeon Hd 5770 for a while now and i have decided to upgrade. The card i bought is a Radeon Hd 7770 i installed it but it wont display anything to my monitor. i hear a post beep but my monitor still says no signal. i have no clue as to what is happening and i want this card to work badly.
Specs:
AMD FX-6100@3.3GHz
Asus sabertooth 990FX
2x4 Corsair Vengence ram
Coolmax 600w PSU (i know it sucks but i was scraped for cash)
Radeon HD 5770(currently due to the 7770 not working)

i have no idea why this card is not working even though the 5770 draws about 30W more than the 7770. Please somebody help me figure out what in the world is going on.

The same thing happened to me about 2 hours ago. I found out that I didnt plugin a pcei cable to the side of the graphics card so it wasn't getting any power from the power supply. Try plugging it in if all you did was insert it into the motherboard like I did.
