need some help on XAMPP /apache

I am quite a newbie on the xampp and the contents, but wanted do some tests where I would like to run the apache. Got it somehow half working. The apache was on, at least it grabbed the port 80 and so on, but the defoult site under htdoc could not be displayed.
I tried to follow all instructions in the config files, but no luck.

I there an specialist for that around?

Need simply to launch the apache, apche only would be fine.

The start-apache.bat does not work somehow, the apache starts , but the pc crashes that way every time. The start via xampp start works however, but not to 100%.
