Recurring random blue screens

Hi,

I would firstly recommend to remove Optimiser pro, as this program is possibly malware.
If you have trouble uninstalling download and install Revo Uninstaller free from here:

Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems

Opt for "Advanced Mode" and uninstall the software (also delete the leftover registry entries).

Also please install Windows Service Pack 1 as it will increase system stability.
Then once installed please run Windows Updates and install all the latest updates.
