Computer constantly freezing shortly after start up sometimes with a blue screen

Recently my computer has been freezing almost as soon as it starts up to maybe just over an hour after, no virus's have shown up on scans done. I have absolutely no idea why it is doing this. Please help!
 
Test the hard drive by going to computer, and right-click on the C drive. Select Properties, tools, check now. Put a check mark in the 2 boxes to set a check on the next start up

I'm not really the greatest computer-smarts person, and I don't pretend to be, but it seems that definitely did something and I've had no crash or freezes since the test. So if that's all I had to do thank you! :)
