My HIS AMD 6870 died. No video, no keyboard, no lights on USB units, and nothing. Substitute a older video card and keyboard lights lite, mouse connection lite, some USB units lite, no monitor lighting at all.
Pulled video card and replaced it with a ZOTAC GeForce GTX 550 Ti.
Obviously, could not remove the old video info and could not install the new. Computer now has the replacement card, keyboard lite, mouse lite, some USB lite, and no monitor lite. Currently set monitor to HDMI and graphics card to HDMI also.
How to I get this to light up the monitor so I can get the use of the computer again?
Need your help and instructions as to how to proceed.
Windows 7 SP1 64bit
Changed monitors and up it came in the generic vga, deleted prior software, and installed the current software for the other card.
