Hello and thank you for taking interest in my problem! I recently got an ATI Radeon x850 Pro
and am attempting to install it on my desktop PC. On my first attempt everything worked fine. Here is what I did:
- Powered down machine. (Did not disable onboard graphics in device manager because it it my understanding that this is an automatic process when installing a new graphics card.)
- Set display detection in BIOS to AGP/ONBOARD
- Removed stock 250w psu
- Installed aftermarket 300w psu (ATI "recommends" 350w or better)
- Installed the card
- Plugged the monitor into the VGA port on the card
- Powered up machine
- Booted to Windows and installed the driver
- Ran dxdiag and everything tested ok but noticed that the test option for AGP Texture Acceleration wasn't available
- Tested out a game (Dungeons And Dragons Online > system requirements
- The game worked fine for about 10 minutes but locked up so I had to manually reboot.
- On reboot, I got no output from the monitor so I tried plugging the monitor into the onboard VGA port and still no output.
- Powered down
- Removed the card from the motherboard and kept the monitor plugged into the onboard VGA port
- Powered up
- Uninstalled all ATI graphics drivers
- Powered down
- Reinstalled card to the motherboard
- Powered up and still no output from either the card or on board VGA ports.
So we came to the conclusion that I needed to upgrade the power supply. So today I went to the local computer store and picked up a 450w Tiger psu. While I was there I spoke with a technician and he told me that it could potentially be that the motherboard
may not "like" or be compatible with the graphics card. So I took home my new psu and gave it a try. After installing the new psu I am still getting NO OUTPUT from either VGA port. I tried installing the drivers first but the driver I downloaded directly from ATI will not allow me to install them without the card being installed.
- Found I didn't have the latest bios installed because HP doesn't update their drivers support site
- Flashed the new BIOS and tried the card without any luck
- Reset the CMOS and tried the card without any luck.
Any help with this issue would be greatly appreciated! Thanks.
