1. Try some of the things listed below. But first make a backup copy of your presentation and use it, not your original file. Never try any of these recovery techniques on your only copy of a presentation.
Things to try:
-If you run PowerPoint 2003, choose Help, About Microsoft PowerPoint from the main menu bar. If the About screen doesn't indicate that you have SP1 (Service Pack 1) or higher, you should update your copy of PowerPoint. Choose Help, Check For Updates. When the Office Downloads page opens in your browser, click "Check for Updates" and apply the recommended hotfixes and/or service packs.
-If you run Windows XP and have installed SP1, see Files open as Read-Only after installing Windows XP SP1, Other file/path related problems
-Open a blank presentation (You can apply the template used for the damaged file, if applicable. That might help cut down on reformatting.)
-From the main menu, choose Insert, Slides from File (or if you use PowerPoint 2007, Home tab, New Slides (bottom of button), Reuse Slides.
-Try to insert slides individually if you're not able to insert the whole thing
2. If your file became corrupted when PowerPoint or your computer crashed, there may be a temporary version of the file in your TEMP directory. If so, you can try the aforementioned Insert, Slides From File and browse to that file. Or you can try changing the file's extension to PPT and see if you can open it from within PowerPoint using File, Open. You could also do a search for *.TMP files on the off chance that it's not in your TEMP directory.
3. If nothing else works, try opening the presentation in Word to see if you can at least recover the text:
-Start Word and choose File, Open
-Choose file type "Recover text from any document"
-Edit the file as needed
4. If all these three methods don't work, then use third party software PowerPoint Repair Toolbox
