Firefox and other apps crashing

[All_Is_Great]

For the past couple of weeks, firefox has been crashing ALOT. Sometimes, it's when I open it just for a second, and others, it's when I open up a page. Most times, I have to open it several times to get to it work for a while without crashing. Also, this has also been happening to my other apps, albeit less often (although that might be because I use them less).

 

In addition, sometimes a popup comes up on the taskbar, something about DEP? I can't remember what letters, but I'll add info when I see it again.

 

As well as firefox, sometimes I get "Windows Explorer has stopped working", then "Windows is restarting", and everything disappears except my background.

 

This is really frustrating as you can probably see, but I have no idea what's wrong. I've ran several scans with Malwarebytes, but nothing has been found.

Have you got the latest version of Firefox? (3.6.8)

Nope, the auto updater thing never came up because firefox kept crashing lol.

I'll download it right now.

Well, it's going on with more than just firefox, so I don't think uninstalling and reinstalling will help.

 

But I will try the chkdsk thing you speak of.
