Graphics Card Problems

You really don't help yourself if you don't post infomation as to what model PC, case size, OS etc.  Post this information and someone might be able to help you.

 

Also, I've got the newest A08 bios.

I am having the exact same problem.  I install the eVGA e-GeForce FX 5700LE 256MB DDR AGP card into my Dell Optiplex GX260 tower form factor with 1GB of RAM and I cannot even get it to power up.  I sent the first card back as dead on arrival, but my second card is doing the same thing.  BTW I tested both cards on two separate systems and neither card worked on either of the machines.  The power light of the GX260 is blinking amber and none of the diagnostic lights on the back turn on.  From the user guides I've found online, this tells me that there is a bad card causing the PC to not even try to boot (pre-BIOS).  When I talked to nVidia, they said the card should be completely compatible.  The recommended a power supply upgrade, but said the PC should boot up with the original power supply (I believe is 250W).

Dell's User's Guide states, power supply wattage for "form factor computer" is 160W.

Power

DC power supply:

Wattage

small form-factor computer: 160 W
small desktop computer: 180 W
small mini-tower computer: 250 W

Hope this helps, Dan

I have the small mini-tower and thats why I have 250W.  "form factor" is just a descriptor like a dimension such as length.  It's the "tower" part of the descriptor that means anything, the "form factor" is equivalent to something like "inches long."
