Trying to install XFX R6770 core edition on Dell E521

Ok....I tried this new graphics card on my Emachines comp but that particular comp has integrated graphics that nobody on earth seems to know how to disable....and we have tried everything since July 12! So I decided to upgrade my older Dell E521 and insert the card there....but OF COURSE im just having more issues. He uses a Sanyo 26" flat panel tv as a monitor but when I hooked it up with a HDMI from the card to tv I got the same message that I did with the emachines comp saying no signal. The cards fan is working well...I have the card plugged into the power source. The disc will not load the drivers...says to go to find the latest driver. But I don't find anything other than an amd catalyst assuming thats what i need considering how long and hard I looked. I will post what Dell said the specs were...wasn't sure what everyone would want so I just copied and pasted. Note--I upgraded the power supply to a Thermaltake 600W..I had issues with the Dell and the hard drive died so I just upgraded it to a new hard drive Western the same time I had to wipe the whole thing out and do a new install of the OS taking it from a Windows Vista 32 bit to Windows 7 32 bit Home Premium edition. I added some memory as well and it now has 4GB loaded. I know a lot of people will probably tell me to update the processor but after the surprise hard drive need and the new power supply etc...this girl is tapped! were the former specs on the Dell (Btw, while the card does fit the comp, it did not fit the case. It was about 1/4 an inch to far past the last remaining slot so I hillbilly modified the case with some tin works I say! And it did but I have yet to get the actual card running!)

  1. Onboard graphics are normally disabled in the BIOS. If the Dell has onboard graphics as well you might want to check the BIOS to see if it is enabled. If it is then that could be the problem. Connect the monitor to the onboard graphics adapter (usually a VGA connection) Press F2 to get into the BIOS when you first start the computer, there should be a setting for video, make sure it is set to Auto and not onboard. Once you have done this then shut down the computer, connect the monitor to the recently added graphics card and reboot.
