1 No you don't have do the first thing I seid try the sencond. Also, you could uninstall programs that you never use just make sure they are not of something inportion.
If you have systeam restore or systeam protaction set up. (same thing) You could do that type in the suerch menu after hit start systeam resore. Then click chose difforent restore point. Click the one that says upgrade of seicrey ecales.
2. Also, if you don't want to do that you type in the serch menu msconfig click setup and uncheck THE PROGRAMS THAT YOUR SURE YOU DON'T NEED AT START UP. Don't disable siritey or windows oportys syteam or framwork or any sevices. For instens you can disable offfice 2010 notepad at start up. Create an systeam restore point before this that why if you diable something you bring it back. Or better wirte down your disableing. After that restart your computer and see if it works.
Good luck let me know if need more help
