Boot your system from the Vista disk and choose repair.

I suspect your BSOD are caused by system corruption rather than the program you have installed. It may just be coincidence that it happened at the same time.

Did the computer go through a disruptive shutdown while you were installing the optimiser (Power cut).

This can often cause problems with the HD.

I use that and haven't had any problems. You can disable it as a startup program as well with Win Defenders startup manager or msconfig.
You can schedule a checkdisk to run on bootup, check both options and reboot to start it. This tutorial will show you how, and also run SFC to see if it can help.


Startup Programs - Enable or Disable
Check Disk - chkdsk
System Files - SFC Command
