Solved problem setting up video card

Hewlett-packard / A6407c

Specs: Windows 7, Athiix4/6gb
My PC just arrived today, boots and works everything is good, but when I put in this Radeon 5670 and go to device manager to disable the onboard graphics 4200HD I don't see the 5670 listing in the device manager at all just the 4200HD, so I disable the onboard restart plug into the 5670 nothing, plug into the onboard works fine -_-

I don't know what I am doing wrong. I went to into BIOS and made PCI-E my main but still nothing. I'm pretty sure the graphics card works since the fan spins on it.

i'm just confused.

According to the specs from HP, it has a 300 watt power supply. The 5670 needs 24 amps on the 12 volt rail, and a 400 watt power supply. Open the case and list what you see on the psu label. I highly suspect a crappy power supply. The fans will spin, but not enough amperage to fire up the card.

it's a 300watt with 19amps on the 12v.

whenever I disable the 4200HD display adapter shutdown and power up sounds like the card revs up and the ran is spinning.

shouldn't it show a display adapter?

I just plugged in my old 9400gt that I ran on my last computer same specs for PSU showing no adapter for that either.

✔ Best Answer
"I don't know what I am doing wrong"

Are you following these steps?

1. shutdown the computer & unplug the power cord
2. lay the tower on it's side & remove the side panel
3. insert PCIe video card in the slot & secure in place with screw
4. Connect 6-pin PCIe plug to rear of card (if required)
5. replace side panel
6. stand tower upright & connect monitor cable to new card
7. plug in power cord & boot system
8. immediately enter BIOS - disable onboard video, disable shared memory, change initial display to PCIe slot - save settings & exit
9. enter Windows & install latest available AMD/ATI drivers

NOTE: notice that nothing is mentioned about Device Manager.

thanks you two for responding.

I just got it to work after going into safe mode.

I don't know why I had to do that, but it finally recognized the card.

I was pretty close to buying a new PSU, but I was very confident it wasn't the PSU.

will get a new PSU if I ever need to upgrade to a 6770 or 6850.
