I just bought a new sapphire hd 3850 ati (agp) graphics card to replace my onboard video. I installed it and everything seems to be fitted properly. However when I start my computer nothing shows on the monitor and the indicator light shows orange. No beeps either.
I just found out that the card requires 450W. My psu only does 350W. Will that prevent the card from working?
I have a few other questions to determine the problem:
1) Is a graphics card fan supposed to turn on as soon as you start your computer?
2) What does it mean if the fan runs (constantly, not flickers) when the cord to the psu is disconnected but the computer is on?
3) When you install a new modern graphics card, do you have to mess around with BIOS settings or does the card drivers reconfigure them automatically?
