Whats the model of your TV. Very rarely does a tv actually accept a 100hz+ input. Most tvs achieve their advertised refresh rate by repeating frames to simulate a higher refresh rate. Most tvs will only accept a 30 or 60hz input.

1) No idea as I don't know what TV you actually have.
2) If the TV has a dedicated PC input using DVI then it may support 100Hz input.
3) It may also be an INTERNAL refresh rate. 100Hz sounds like some TV's I've seen that were 50Hz (PAL) for inputs that doubled the scan rate internally to avoid flicker (or motion smoothing by creating new frames).
?
The bottom line is you really need to consult your manual and/or just try connecting a PC and see what you can do.
Other:
Adapter?
If you mean a VGA adapter then no. In fact, to be clear the DVI-I output on a computer has both DIGITAL and ANALOG outputs so if you use a VGA ADAPTER you're simply connecting to the analog outputs.
(The digital signal is split inside the graphics section of the computer. The digital comes straight out, whereas the analog goes through a DAC or Digital to Analog Converter. Both sets of pins end up at the DVI-I output but you can only connect to one set or the other.)
Connecting to the analog outputs is the same on a dedicated VGA output, or using a VGA adapter on either single or dual-link DVI.

Emil_Meld :
Cant seem to find exact model number, buts its just a standard Bravia 3D. A Single link should be fine then?
My guess is it's fine in that it's probably going to work with ANY computer either at 50Hz (PAL) or 60Hz (NTSC).
It's a 3D and since it's 100Hz it sounds like PAL thus it's taking a 50Hz signal likely and showing it twice for 3D thus 100Hz. So you might be limited to 50FPS/50Hz via the computer input.
Update:
Probably 60Hz 1080p max for computer even if primarily a PAL TV.

Some TVs can do native 100/120 inputs, but it's rare. What they do is accept a 50/60 signal, and repeat the frames internally, for instance. 24p (24 Hz) blu-ray content is going to repeat each frame 4 times as the TV will run at 96 Hz. On a 120 Hz TV, it's repeated 5 times, and the refresh rate remains the same, where as on a 100 Hz TV it's lowered by 4 Hz. This is to get rid of telecine.
Now here is something important to know, that a lot of people don't quite understand. If you have a native 100/120 Hz TV, or native 200/240 Hz TV, then that is a fixed/static rate, meaning there is no extra input lag added by processing the frames. The result is far less ghosting, regardless what FPS a game is running at for instance.
However, you won't get smoother game play, as that requires more frames to be displayed, but isn't possible, so you're only getting 50% of the advantage of a higher refresh rate. Same goes for monitors.
Regarding cables, it's always best to stick to digital when using it with a TV, because HDMI doesn't support all resolutions and refresh rates just because it's got the bandwidth for it. VGA is old, and will reduce picture quality depending on interference and length, as well as the quality of the cable.
Lastly, only HDMI will do HDCP handshake when used with a TV, probably some exceptions but HDMI is the standard. DVI can't do it, neither can VGA.
