Upload file over 25MB not working

I have been struggling with the uploading of files. First it was files over 1MB which I made the change on the contact form:
<p>File Name*
[file* file limit:60mb filetypes:doc|docx|csv|eps|idml|indd|jpg|jpeg|mdb|mdbx|pdf|png|psd|pub|rar|sitx|tif|tiff|txt|xls|xlsx|xml|zip]</p>

The it was files over 2MB so i made the change to php.ini:
upload_max_filesize = 75M
post_max_size = 100M
memory_limit = 250M

Now I can succesfully upload files as large as 25MB but when I try a file larger it tries to upload it never errors out just. Next to the send button it just has the spinning arrows.
