Specs: Windows Vista
I just bought a new graphics card and power source. Everything is working fine with the power source, but when I put the graphics card in, the monitor will not work. The directions with the graphics card say to install the drivers after I installed the card. But I can't install the drivers if the monitor doesn't work. The new power source is 500W so having enough power shouldn't be the issue. I have also gone into bios and changed the input to the PCI E slot. There is nothing on the monitor except a message saying that it is going to sleep.

GeForce GT 240
500W Power source.
HP Pavillion 6700
previous had onboard video, no card.

The GT 240 is a good entry level gaming card with very low power requirements. Chances are good you didn't need to upgrade the power supply. That being said.....

"The new power source is 500W so having enough power shouldn't be the issue"

Wattage is NOT the primary issue to consider when choosing a PSU, amperage is. Plus the PSU should be made by a company with a good reputation for quality & reliability. Price is a pretty fair indicator of quality, so is weight. A cheap PSU is usually made from low cost/lightweight components (lightweight heatsinks, cheap capacitors, light gauge wiring, etc)...that's what makes them cheap. The makers of these cheap units tend to exaggerate their wattage & amperage specs too.

What I'm getting at is you can't make a blanket statement that the PSU isn't the problem because it's a 500W'er. It's completely possible that you downgraded if you didn't get a decent unit. How about posting the make/model, amperage specs & what you paid for it?

The PSU is a Rocketfish - 500-Watt ATX and I paid $80.

I fixed my problem though and it had nothing to do with the PSU. I had to deactivate my onboard graphics card before the new card could take over.

Start--Control Panel--System--Device Manager--Display Adapters-- Right click on on board graphics card and click to deactivate. Now go install the new card and it will load and tell you to install the new drivers.
