Hi,
What is this fucking mania of uninstalling software at the slightest problem!
You could have also reinstalled Windows and even, why not, thrown your PC in the trash to buy another one.
You didn't think to check out the php_error.log and apache_error.log files and possibly the Windows Event Viewer.
In 99.9% of the cases the solution to your problem is to go and see what errors are generated before the crash, as you say, takes place.
And we are not soothsayers, thank you to
