Monitor is dark after I installed new video card

December 29, 2011 at 22:01:29
Specs: Windows XP Prof SP3, Pentium 4HT 2.6GHz/1GB
I upgraded GeForce 6200, AGP 8X, 256MB DDR with an Axle AGP(8x) 7950GT, 512MB/256bit video card. My PC is an HP Pavilion a250y Desktop: D7219P.

I am using an HP 2007W monitor, which went dark; however before it did the message on the screen was: No VGA input No DVI input.

The older card had a VGA and a DVI port. The new card had two DVI ports. The monitor has a VGA port and a DVI-D port. Previous card was connected from the VGA port to VGA port. In my first attempt, I used VGA/DVI adapter on PC port (video card) and VGA port on monitor. In second attempt, I used VGA/DVI adapter on PC port and VGA/DVI adapter in DVI-D port on monitor.

Because these met with no success, I bought a DVI-D to DVI-D cable and connected the monitor and the PC using only the DVI ports. Still no success.

My Power Supply is sufficient. I have a 450W Cooler Master.

My motherboard is an ASUS 45D-LA Stingray. Graphics card is right out of the box. Old card works when replaced between each attempt.

I seem to be missing a step to get monitor and new card in sync.

Did u connect the additional power cable to the 4 pin power port on the rear of the video card?
It's not wise to invest alot of cash on old system.

Hello Kuwese:

No I did not. I did not know this was a power port. I have three "loose" or unused connectors that will fit there. Can any of those be used? They are marked P4, P6 and P7. I have two other unused connectors but they have "heads" that will not fit the 4-pin power port. They are marked P9 and P12.

check whether your powersupply has a single +12V rail or multiple +12V rails.
If a single rail then use any of the 4 pin molex connectors. If it is split rail then spread the load.

Thanks, Richard,

I am not sure that I know what a 12v rail is, but I just checked the specs for my CoolerMaster Real Power 450W Power Supply and the review attached to the specs says that it has two 12 volt rails.

That helps. Thanks.

The new video card is getting power, but the monitor is still telling me that there is no signal.
