Howdy - I have a Dell Precision T7500 using two AMD W7000 video cards (not the best choice of video card, I know). I cloned the Win 7 64 bit and placed the clone in a Dell Precision 690. From the sound of the hard drive on booting, the 690 seems to have booted but without video.
At first I had an AMD 2450 Firepro in the 690 and with that card I saw the boot-up posting, memory testing, etc. but still a blank screen after booting.
Next, I put in the AMD W7000 card (this is the card that was originally in the T7500 so the video drivers are set for W7000) and still I get a blank screen after booting; but another observation: With the W7000 (trying all 4 spigots) the monitor ON LIGHT is blinking which normally means the monitor is not connected to a card. This did not happen with the AMD 2450 Firepro video card.
Next, I tried one of those USB to monitor devices (which normally works on other machines and did once work on this 690) and still I get blank screen and a blinking monitor light meaning (to me) no monitor connection.
I thank you in advance and I would greatly appreciate ANY suggestions, other than I should kill myself.
For instance are there ANY video cards that always work or is there a way around this?
