Video Card Replaced but now Screen flickers

HI Guys and Gals-

Late this summer I had the Video Card replaced in this system. It was done by a very good place here in Portland Maine. I was not able to use the computer until recently as we have new computers in our offices. Now , wanting to get back onto this computer I plugged it into my old monitor and it flickers and the grays are like a pink. I tried 2 new adaptor chords to see if it was them and its doing the same thing.

My question is this (i don't have a spare monitor handy) given the monitor Acer is 12 years old is it now the monitor? (the startup screen does come on but the actual picture doesn't stay on continual enough to sign in.) Thoughts ?

Nick
