What it is
A GCN road bike maintenance tutorial showing how to tighten a threadless headset to remove creaks, rattles and play at the front of the bike. It covers the tools needed, such as a torque wrench and 4, 5 and 6mm allen keys, and the safe order of adjustment.

Tightening the screws on the stem is not enough. There are videos on YouTube and on Parktools' site that show how to adjust the headset properly. [this video]

Very likley you have to tighten the screw in the middle of the stem, aka the one in the middle of the cap that says "Giant". You don't want to tighten into too much however, because then steering will become very hard. This video gives good explanations. The procedure is both the same on roadbike and mountain bike. If you feel unsure what to do, got to your LBS to repair this - if wheel/handlebar become desyncronized while riding the bike you'll face major injuries.

I have a GT Grade Carbon which is designed and produced by the same corporation as your Cannondale. I have the described effect on high speed braking only which is quite common problem and it's easy to find information about it over the internet. Moreover, this effect was one of the reasons manufacturers switched to through-axles on road bikes too, and I believe it makes sense because this vibration makes quick-release loose with time. Make sure to check it more often while you have this effect unresolved. I wouldn't say that I'm confident on why it happens to you during the normal operation, but some basic sense suggests that it could be something loose, online forums suggest that it could

Nowadays most bikes have a 'threadless' headset. The steerer tube of the fork protrudes out of the frame's head tube and the stem clamps onto it. The stem serves to hold the whole system together and apply a little pre-load force onto the bearings to remove any play or movement. Without this pre-load the bearings will become damaged as the fork rocks in the frame slightly as you go over bumps. If you have a threadless headset and your stem has rotated on the steerer tube, the chances are the clamp bolts are too loose and you have lost the bearing pre-load. It's not too difficult to re-adjust the stem (and re-align the stem and wheel at the same time). There are many video's on YouTube that s

Make sure you adjust the center bolt on top first while the 2 stem bolts on the side are still loose. Only tighten it a little, until there is no more headset play. That preloads the bearings, and then the 2 stem bolts lock everything in place. Do not tighten the stem bolts first. That will make the center bolt unable to preload the bearings. See this video: Altough, I'm wondering if your stem has the same diameter as the fork it's clamped on. If the stem has a larger diameter, it is not compatible with the fork, and would slide around no matter how much you tighten it, making the handlebars turn without the wheel. There are these standards for threadless stems: 3.2.2 Threadless stems TABLE
