I have always used 2 registry scan tools--Norton One Button Check Up and System Mechanic.
I have used these programs successfully for years.
Now I cannot run these registry tools without my PC restarting shortly after the scan begins.

Not sure what changes (hardware/software/config) prompted this behavior and I cannot recall how long I have had the issue (6 mos?), but I have reached the point where it is just pi**ing me off now and I am seeking solutions.

I run a Pentium Core 2 Duo with 1GB DDR2 RAM.
Windows XP Home SP2.

What the heck (if anything) is the scan hitting that is causing this and more importantly what is the resolution?

Thanks in advance,
C.
