I built my computer about a year ago and it worked flawlessly until last week my hd3870 crapped on me so I got the hd 4870 today and now I have no signal to my monitor. I have everything connected the right the cpu fan, the cpu 4 pin, the atx mobo plug, the ram properly seated, cdrom drive pwoered, and hd powered and conected via sata, and the 2 6pin connectors in my hd 4870.When I turn on my computer the three red lights flash on the hd4870 for a second then turn off and the graphics card appears to be working, but I just don't have a signal. Thanks in advance for your help!

Here's my build

omg i have the exact same problem. everything on my computer works, the video card fan is on and everything. i also see the three flashing red lights on the card for a split sec when i turn on my computer on but "no signal" on the monitor...

i found some good news:

it appears that the red lights flashing are normal but my video card fan speed continues to go at %100 speed and still "no signal". the lights that light up for a sec are: D1602 D1601 and D1603 ( written on your video card) D601 does not light up and I read that if it does light up it means your video card is dead but good thing it didn't.
