Laptop eats System Restore Points--even after out-of-the-box restore

Hello everyone,

I have a repeat problem that I cannot explain: My system creates system restore points just fine (at least, the ones I create manually and can confirm that they are there), but they vanish upon restart.

I have a Toshiba Satellite P750 running Windows 7 Home Premium.

I discovered this issue for the first time in November 2012 when my computer had a hard crash. That was when I learned that it was deleting my restore points. I was forced to do a factory reset. After that, System Restore functioned normally--for a while. Then it began eating restore points again.

About a month ago, I had to do ANOTHER factory reset. Again, System Restore started working--creating and keeping restore points. But just a few weeks into a "brand new" system and they're completely gone again.

I can't understand why this keeps happening even after factory reset.

This is a problem I've investigated multiple times over the last few years and haven't found a solution for yet.

Does anyone here have any advice?

Thanks!

I have had similar problems in the past with System Restore (the restores points don't get lost, they just don't always work) so I turned it off and just depend on imaging now, using Macrium Reflect Free (here is a good tutorial on how to use Macrium Reflect). I've yet to have an image fail to restore.
