Maybe video adapter
(I'd like to stress that this is mostly speculative. Please don't read this as gospel or a guaranteed fix; it's just an idea or two.)
True, it may be the video adapter. But there are a number of different things that can cause a computer to not display anything during its boot, even though you can tell it's booting. The best thing to try first is (and only if you're comfortable digging in a computer) unplug all the peripherals in the machine (e.g. HDD, CD, etc.) and RAM and (if it's an add-on card) the video card and turn on the computer. Obviously, it won't boot properly, but as you slowly add components back in (one at a time) you might find the culprit.
Basically, a problem like this can be traced back to either a short/static build-up in some component or a failing/dead video adapter. If you're getting absolutely no display (which your description indicates) it's definitely a hardware issue of some sort.
Of course, it really helps to have a P.O.S.T. card handy to determine exactly what's going on and most computer shops you take a machine to will have one. Often, local shops will diagnose a problem for free or a nominal fee.
