Windows 7 Toshiba Laptop Freezes Up For Seconds After Showing Desktop

In the last few days my Toshiba Satellite L745-S43210 hasn't been working right. Recently it won't boot up properly. It started to boot up and then it would freeze up seconds after showing my desktop. I managed to go into safe mode and use msconfig to change start up programs and turn it to only the essential items. After that it worked and I tried turning everything back on and it worked fine last night. I assumed it was just overheating from being used so much in the last few days. Now today when I tried starting it up I was able to enter my password but the screen went black with my mouse pointer working. I turned it off and tried again a few times before going into safe mode.

I went back into msconfig again and turned it back to only essential programs and I performed a virus scan with Super Anti-Spyware and Malware Bytes and the only thing that they found were cookies. I cleared them out and booted up windows again and it worked fine. Now I am trying to select only certain programs and choose only the Microsoft, Intel and Toshiba programs/services and now when I boot it up I don't even get the the text box to enter my password, it just shows the blue windows start up screen. Right now I am using Safe Mode With Networking to type this and try messing with start up programs again.
