My sony vaio laptop hangs often

If your having random slow downs while computing then you will have to troubleshoot on your side to find what the problem is. Start on the software side.

1st - Download CCleaner. Click on Tools. Now uninstall any unused program. Please use common sense about this and don't uninstall something your not 100% sure you don't need. If you're unsure, ask us. But get rid of any software that for example sony might have put on there like cd/dvd burning software you don't use.

2nd - re-open CCleaner and go to cleaner section and run the cleaner. Might take a bit if its your first time. Be patient.

3rd - do the registry section as well. Make a back up if your paranoid.

4th - click on the windows start icon, type msconfig click on start up tab. Now check to make sure you don't have an overabundant amount of things starting up. It's hard to say what you may have listed but for example I only have 5 things that start up. Ask if your unsure.

5th - If you have a Hard disk drive and not a solid state drive run disk defragment and go make a cup of coffee because it might take a bit.

Report back.
