Computer Restarts when In Use

Can someone please help??? My computer will restart when I am working on something!

 

Operating system? If XP, turn off restart on errors so you get a BSOD with an error code.

 

How do I do that?

 

Right click my computer>properties>advanced>startup and recovery>uncheck automaticaly restart.
This will give you the time to see and study the BSOD.

Did you pay attention when you install windebug?
I install minutes ago and everything is ok.Read carefully.

 

Thanks Again ... It says I have FILNT.SYS now what?

 

From this very old post http://forums.majorgeeks.com/showthread.php?t=59500
filnt.sys is part of Outpost Firewall. Do you currently use or did you use in the past Outpost?

 

Thank you Thank You Thank You I will uninstall right away. Will that take care of it?

 

We won't know. But it seems to have fixed it for posts I've read on this.
