Hi, last night while watching a Camtasia presentation online my computer crashed and a blue screen error was thrown up on the screen.

Since then sometimes I can boot successfully, just as many times I can't. Also when I click on a program or a file there is hang time...sometimes as much as a minute before the program or file opens for me. Sometimes the screen freezes competely.

I just downloaded and ran Analysis Diagnositc for Windows XP and it returned this warning: THE SYSTEM RESTORE HELPER returned a warning code hr=0x6.

Does anybody know what this code means? Thanks...

You may have a memory problem. Follow this article:

Let us know what happened.

It could be memory like the previous poster suggested or a failing Hard Drive. I would do a back up immediately just in case if you haven't already. Download these utilities to test the system.

Both are bootable CD's and are ISO files that you will need to burn with your favorite burning program
