Okay here goes, I have a Dell Dimension 2350. I recently purchased a Powercolor Radeon 9250 video card to upgrade it with. So I installed compleatly wrong and now I have a problem. Heres what I did.

1. I installed the card in the PCI slot, but left the monitor plugged into the motherboard.
2. I restarted the computer and installed the Drivers for it.
3. I removed the driver for the internal video.
4. I restarted the computer.
5. It rebooted this time in a huge resolution and without all the colors. Don't know what this is called. I shut off the computer to attach the monitor cord to the new video card, but remembered that I needed to change the BIOS settings.
6. I turned the computer on and now all I get is a Blank screen and blinking white dash. The Monitor is plugged into the motherboard. I get nothing through the video card.

What do I do? PLEASE HELP.

Boot into safe mode and install your drivers that way.

How can boot into safe mode? I can't get anything besides a blinking white dash. Please somebody explain this.

Does it POST successfully before you see the white dash blinking?

 

[Powerful Roger]

What do you mean? I'm using another computer to type this right now. The computer dosn't succesfully start up. All it does is blink the white dash.

 

[ebackhus]

How far does it go before you see that?

When I turn on the CPU all I get is a black screen with a blinking white dash. It goes nowhere.

Ok, it might be a good idea to try reseting the BIOS. To do this just open the case sna look for a small silver battery. Remove it for about 30-60 seconds and put it back in. Try booting. Our next target will be your PSU.

Okay, so say that does nothing, what do I do now?

 

[ebackhus]

You tell us your PSU specs: brand, watts, amperes. All of this is shown on the label.

Okay, I have everything the way it was before I installed this thing. It's taken out, all the Drivers for it are gone. Walk me through the process of installing it now. I need to know how to disable my onboard graphics card first and foremost. Please walk me through this.
