I just bought a Radeon HD 6770 graphics card. It is plugged into the only graphics card connector on my motherboard. I have it connected to the power supply (using a 6-pin red connector that says "PCI-E" on it, I think that's the right connector? Mine has a 6-pin and a separate 2-pin connector, but the gfx card only has one 6-pin connector).
I power on the computer, all the fans spin, but I get "No Signal" to the monitor; the monitor works on another PC. Am I connecting something wrong (maybe using the wrong 6-pin)? I literally JUST opened the graphics card box; it was brand new from TigerDirect. All of the below parts are around 2 months old or newer.
- Motherboard: ASUS M5A97 R2.0
- GFX Card: Radeon HD 6770
- RAM: 8GB (Corsair DDR3)
- CPU: AMD Phenom II 965 Black Edition
- Monitor: Acer P215H
- PSU: Thermaltake TR2 700W
Any advice would be greatly appreciated as for the love of me I can't seem to get some simple upgrades working and I've been at it for 3 months now and spent close to $1000 on various parts that don't work. I've had to replace a power supply, a motherboard, and another graphics card because the pieces would not work together, and I have no idea why something seemingly so simple is causing me such grief.
EDIT: This "No Signal" issue has been going on for several months now with a variety of components. I replaced a power supply and motherboard and Sapphire Radeon HD 7850 that I was told were all bad/fried because the monitor never detected the graphics card. Now with a brand new out of the box card I'm still getting that same error so there must be something I am doing wrong (I highly doubt that two different PSUs and gfx cards could both be bad immediately). The only things I haven't swapped out and replaced are the DVD-RW, the hard drive and the case itself (it's a generic black iBuyPower case as the original PC was one of those), everything else has been replaced at least once and still I get this "No Signal" error.
