Sorry for the late reply but yes, I will try that because my computer has been tested with another monitor and the problem was the same. As was the case with another problem that I was having.
In regards to the latter problem when I turned on my computer, it sometimes would go to a black screen with a blinking cursor. In fact, it still does that, but at least boots now. The only problem with this is that there is no longer a visible option to access BIOS mode.
