Windows 7: System Restore

When my PC wouldn't boot a few months back I thought I was safe with system restor. Wrong , there were no points there to restore to. A few week ago when I was having problems there were no restore points either and I discovered the upgrade install method, and got going again. Having recently been helped with PC crashing several times a day (by uninstalling catalyst Control Centre), I seem to be up and running normally again, but there are no rstore points. I asked about this serveal months back and I seem to remember that there is no automatic creation of restore points (ideally twice a week would be good). I followed instructions to set this up, but still they weren';t there when I needed them.

Can anyone help me set my PC to produce restore ponts says every 4 days?

i use this method,

System Restore Point : Create at System Startup

follow the tutorial .
when my computer starts i have a small window opens and a yes or no button , i can choose to create a system restore point at start up.
i do this each morning, if i restart again the same day i dont bother as i have one for that day, you could do similar or click no for 3 days and yes on the fourth day.
