Does it happen on your user account only or everyone who uses your PC?
Also try moving the main folder (Located C: Program Files\???\Dead Space)
Move the main folder ALL the files to "My Documents"
Just another suggestion since (My own personal expericance) when my GTA San Andreas had this problem (Oddly yesterday :/ ) Someone suggested moving to My Documents and it works!
Try that, if not move it back to where it originally was.

have you checked the event viewer/log?

Well, actually I downloaded Dead Space from Steam, so I think it's not possible move the main folder to another location, but thanks anyway TheNathanNS.

I checked the event viewer several times, but the only event was 'unexpected power off', no driver crashes, no memory read error, no nothing but 'unexpected power off'... of course, I knew that, it was myself shutting the damn thing off! Thanks, Lord Impaler

It is possible to move the folder.
I should imagine the folder is called "Steam" and inside is "Dead Space"?
If so you can move the folder by searching for a folder named Dead Space and it should come up (I think, I do not use Steam)
C:\Programs And Files\Steam\Dead Space

I do use Steam and it's not that easy, doh! I tried...

Thanks again!!

Is the folder hidden?If so unhide it.
Try this
Right click on your Dead Space folder and make sure "Read Only" is not clicked.
If it is, unclick it. It could help a bit.

Nope, it's not hidden, but Steam games are in a common folder called Steamapps, and they share some files. It's a little bit too obscure for me just figure out what file goes with what game, there isn't just a 'Dead Space' folder...

But I have this problem with other no Steam games, so it's not something specific of Dead Space or Steam games.

As said before, thank you for your help!!
