Your #8 response makes no sense to me. Your original graphics card is the 8300GS with an nvidia GPU. Your new card is a HD6770 with an AMD GPU.

The differences between on HD6770 may affect performance but the fact remains the GPU still requires more power than your power supply can provide.

If you are confused by AMD vs Sapphire then let me explain. AMD makes the GPU and sells it to any graphics card maker who then incorporates it into their graphics card. The GPU is the heart of the graphics card. They may run the GPU at different frequencies and/or use different types and/or amounts of onboard memory but all HD6770 cards will have similar performance in relation to other series.

Post your system specs including the complete model of the power supply.

If you have a power supply with multiple 12V rails there may not be enough power to run that card.

Do you see any POST screens prior to the computer trying to start Windows?

Are you sure the card is fully seated?

Did you unplug the computer before changing out the cards? Did you remove the geforce drivers before changing out the cards? When going from nvidia to AMD you need to do that.

"my old card (gs8300) PCIx also works perfectly"

PCIx & PCIe are 2 completely different things. I doubt you have PCIx. And your old card is probably an 8300 GS, not a gs8300. It's important to get the terminology right.

"I have 600watt Power Supply Cooler Master"

Cooler Master makes a lot of different PSU series - Elite, eXtreme, GX, etc. The eXtreme series is very low end. If that's what you have, you'll find this interesting:

Do you see any POST screens prior to the computer trying to start Windows?

No, Monitor has no signal.

Are you sure the card is fully seated?

Yes , sure

Did you unplug the computer before changing out the cards?

No, just the card.

Did you remove the geforce drivers before changing out the cards? When going from nvidia to AMD you need to do that.

Yes , I removed the graphics drivers .

The Elite series is even more low end than the eXtreme series. Plus 400W isn't enough. Sapphire recommends 450W minimum.

Here's a couple of power supply possibilities from the same site you bought the card from:

Your power supply is under sized for your system. The new card draws more watts than the old. Disconnecting drives will not compensate.

At this time I would verify there is not damage before buying a new power supply. Reinstall the original graphics card. If you don't hear beeps and see any POST screens you may have damaged the power supply and possibly even more. Hopefully no damage has been done.

Once you get into Windows and you are ready to install a new power supply and the AMD card you need to go into Device Manager and remove the 8300GS listing from there.

Shut down and unplug then depress the power button. Now you can change out the parts.
