I just bought a Radeon X1950PRO 512MB 256-bit GDDR3 AGP 8X IceQ 3 Turbo HDCP Video Card, installed it in my computer, and connected it to my monitor using a DVI to VGA adapter (the card only has dvi output)... When i boot up, all i get it a blank screen. The fan on the card is spinning and the light on it is on. I have no idea what I did wrong. My old video card is a BFG GeForce FX 5500 OC 128MB 8x AGP Video Card.|||Several possibilities here, the system requirements for your new card is:
Radeon X1950 pro
AGP based PC is required slot available on the motherboard
-----------
Connection to the system power supply is required
450-Watt power supply or greater, 30 AMPS, 12 volt rail recommended
-----------
512MB of system memory, or more recommended
CD-ROM drive (for installtion software)
DVD playback requires DVD drive and decoder software (not included)
Operating System:
- Windows XP
- XP-64
GeForce 5500
Windows 98SE/Me/2000/XP
Available AGP slot
CD-ROM drive (to load drivers CD)
As you can see, the old video card was designed to work with any power supply and did not require a direct connection from the power supply. Your new Radeon X1950 Pro requires a minimum power supply size of 450 watts AND 30AMPS plus a power connection directly off the power supply. Thus you need to check the rating on your current power supply to see if it conforms to the minimum total output of at least 450 watts and 30 amps. Also, did you install the card with the direct power feed from the power supply? It would be a plug like your hard drive uses that plugs directly into a slot on the new video card, so the card can draw power through the AGP port as well as directly from the power supply.
This is most probably your current issue, an insufficient sized power supply and/or having not supplied to direct power feed from the power supply. If you system is a pre-built from a manufacturer like Dell, Gateway, HP, etc, they only use the smallest power supply required to support the components they installed initially, if you add anything that draws power later, you almost always end up having to replace the power supply too.
Once you correct the power supply problem and the system starts up properly with video, you are going to need to goto Start, Control Panel, Add/Remove Programs and remove your nvidia drivers, once done will require you to reboot your system. You will know you did it right when you restart and all the icons are huge on the screen. Now goto: http://ati.amd.com/support/driver.html select the appropriate operating system in the first window, Radeon in the second, and then Radeon 1950 series in the last and press the green go button, this will allow you to download the most current video drivers for the new card. Once downloaded to your machine, run the program to install the current catalyst software for your new video card. Upon completion of this installation, the system should reboot yet again, and you should have everything working properly.|||1. make sure your powersupply meets the video card requirements
2. make sure the necessary power connectors for the video card are plugged in and the card is firmly seated in the slot
3. make sure you completely remove all nvidia video drivers (it is recommended that you use a driver cleaner utility) because you're switching from nvidia to ati [although this is probably not the problem because its not even booting up]
4. try increasing agp aperture size in bios to 256mb
5. it could be a DOA|||did the software load? without the system knowing it's there, the card is useless. read the manual and check what you did to see if you followed ALL the instructions just as they are in the manual.|||have you checked to ensure you meet the power requirements? the x1950 will be a considerable amount higher power requirement then the old fx5500. Do you get any beeps during bootup?|||Take it out and push it back in...most likely is that its getting a connection to power, but not connecting to your video display on your motherboard.|||get the software update version
