Win7 64bits crashes on accessing restore points

Hi everyone,
New to the forum, but long time Windows user. I have Windows 7 Pro 64 bits SP1 installed.

Here's the deal. My system crashed overnight (no one knows why). When it boots back up, it works fine for a while and then Freezes (no more mouse mouvement, no more num-lock light switching on/off). Windows Event is of course empty.

I was able to figure out where the source of the problem is. Seems that the whole Restore Point thing is corrupted. Including the Auto part where once in a while it creates a back-up point during boot up.

I have tried in normal mode:
1 - Accesing the restore to a previous point through Windows normal mode: Freezes every single time when i hit the configure button to remove the Restore point from my C:\ Drive.
2 - Accessing it through CCLeaner and trying to remove a single Restore Point: Freezes.
3 - Accessing it through Disk Cleaner, Delete all the restore points. It works... but never ever delete anything.

I have tried in Safe Mode:
1 - Accessing the Security Protection tab: no succes It doesn't show in the tab
2 - Accessing the DiskCleaner, Delete all the restore points: Error 1084, not working in safe mode.
3 - Deleting the restore points using CCleaner, Error 1084 not working in safe mode.

I have scan the PC in safe mode with Eset node32, Malwarebytes and Spybot and all is good.

so in short: My whole Restore and Restore Auto-Creation point is completly corrupted and i'm looking for a way to fix that! Either using the registry or anything else. Anyone has an idea? No i did not instal software lately (it's been 2 monthes), no i did not change any hardware for the past 2 years.

thanks eveyrone!

Hi KoolKat,
thanks for you answer:

1 - The Scan has been ran multiple time without any error to report (done from SafeMode).
2 - I was able to activate the Add/Remove software option using a regedit modification and Eset and SpyBot are now uninstall. Unfortunatly, i can't install/run MSE since it doesn't want to install from SafeMode. I tried it from Normal Windows but since i can't get my PC to run more then 1 or 2 minutes before crashing, it did not install.
3 - Since it does not create a BSOD, i don't know if you'll get the information you need. I will crash my PC, then log back in safe mode and run it. I will attach the .zip in the next minutes.

thanks again.

Hi,
Here is the result attached.
I do not have any coredump or dumplogs. There was some errors running the program.
I did try to re-install MSE, unfortunatly it crashed before finishing it so back in SafeMode i am.

Hi Kat,
Cannot reach that screen! Has soon as something acces the Restore Point it crashes and the funny thing is that screen is not available through SafeMode (or at least, i don't know how to get there).

Thanks.

Hi Karlsnooks,
The action that i did previous to the crash was a simple DVD Shrink backup of my girl's new TinkerBell DVD.
Then i left with everything working, to come back to a frozen screen. I came back the next day but the time on the frozen screen was roughly 19h15, about 1h after the DVD backup.

I still have plenty of disk space and as i said, SafeMode works flawlesly! I'll try to delete some stuff and take backups but i still think since it seems to be OS related that it's fixable!
Thanks in advance guys!
