XP.  by the way, do u know how to view the minidump file other than using the microsoft windows debugging tool?

Don't know wor.  

Did you install some new apps, then this blue scren happens?

I have to trace back the dates to find out.. it is possible.

ben, oh u know what, power director was one of them!

but you are using it too and you don't have problem.. is it possible that it is conflicting with some of my other apps?

I don't have any problems after I installed it.  But the point is: I am using Win7.  It also may conflict with other apps, it is possible.  You can uninstall it and test it out.

You know, when I look at the date, I think power director was the only app I installed before it start crashing frequently (unless there are plugins or some upgrades that I don't remember installed).  Let me uninstall it and give it a week or two to see if it blue screen again.  If so, then it wasn't PD, it's probably something else?

I think that's the way to troubleshoot this problem.
