Yes, there is a chance but I'm not familiar with PowerPoint. Until someone answers your question just make sure that you DON'T run disk cleanup or any other utility that deletes temp files.
Look in your help files, under the index tab and type "temp file" or "recovery" or any other term that you can think of and you may find the answer there.
There may also be an option under your files menu for recovering temp files
Hope you find it,
