Teamspeak no longer working for me?

My teamspeak has suddenly stopped working completely. It randomly crashed with no warning, and kept doing so afterwards after 2-4 seconds. I tried reinstalling and now it doesnt even want to install anymore, as it also crashes whenever I try to install it. I am no PC nerd or anything like that so if there’s anybody out there who is able to help me, please try to explain it step by step.

could you provide any log ?
without it, we can’t say much.
