I installed an XFX Radeon HD 6970 in my computer along with a new power supply for it. The power supply I used is a Corsair GS600 which is recommended on AMD's site for this card. However, after I pressed the power button, the first thing I noticed was the power button not lighting up. Then the fans kicked in and became absurdly loud which I assume isn't normal. The monitor stayed completely black without changing and had a red light which usually means the computer is on standby.

Before installing the 6970 there was an integrated HD 4200 with a 4 pin connected to it, which I didn't reconnect. I connected a 6 pin and a 6+2 pin into the 6970.

This computer was a prebuilt; The model is an HP Pavilion p6740f.
Specs without card or PSU:
1.5TB SATA Drive
Radeon HD 4200 Integrated
Bestec 250 watt PSU
AMD Phenom II x4 3.0 gHz Processor
8GB RAM (2x 4GB cards)
N-Alvorix-RS880-uATX (Alvorix) Motherboard

Is it a faulty graphics card? Does the motherboard not support the card? I'm kind of lost here, I've tried plugging the monitor into different ports and using different power supply plugs without success.

Welcome to the forums!
I guess you did not take the time to read the requirements of the 6970.
It requires a quality PSU rated at 550watts or better.

00 that is power for the CPU and it need be plugged in.

I bought a Corsair GS600 to go with the card, which has 600 watts of power. I used the 6970 with the GS600. The 250 watt power supply is the stock PSU that came with my computer.

It had two rows and two columns. I think that may be the problem, I didn't plug that in. That's really inconvenient though, because there is no 4 pin in easy reach of the plug. I'll try figuring something out, thanks for the suggestion.

Okay, it turns out the 8 pin connector I didn't use splits into two 4 pin connectors after some investigating. I'll try that solution. Thanks again.
