I am trying to update my system from onboard video to a video card. Since my system already runs ATI Radeon 200 Xpress, I thought that I would have less problems if I stuck with the ATI technology. So I am trying to install a Sapphire Radeon HD 4670 PCIE 2.0 card that has 1GB of DDR3 onboard the card. The problem that I have is that when I install the card, and power up the system, it responds with the BSOD and then starts rebooting before I can get any info off the screen. The cycle continues to occur until I power off the system and remove the card. My motherboard is a MS-7248R Version A-13. In preperation for this upgrade I have done the following items: (1) maxed out memory at 2GB, (2) upgraded from a 300 watt power supply to a 750 watt power supply, (3) added an ASUS Xonar D2 sound card, and (4) downloaded the latest drivers from ATI. My response from ATI was to contact Sapphire. However, either I have the wrong web address or their site is down. I tried to go to
www.sapphiretech.com . Any help in getting the card to work correctly, would greatly be appreciated! Thanks in advance!
