Blue Screen on vista SP2 when installing

[netaware]

I get a blue screen on my Dell 1420 laptop with Vista SP2 when installing.  It happens at different points of installation.  I have tried several times but it keeps happening. I have to go to saf mode to uninstall.
I did not have a previous version of Avast.

Now I do not have any protection!

Please help.

First download and run free Mbam, to check if your system is clean.

Be sure your prior AV is completely removed. (You could need a utility for that)
Here's the one for avast: http://www.avast.com/uninstall-utility
Run this in safe mode before you try another clean install.

Ok I will try that.  What about minidump files, will that help someone troubleshoot?
