What's wrong with my computer? Reboots itself randomly?

Lenovo c540. When it is powered on it turns off and reboots itself and the screen turns black the green lines come up and then it goes to login screen. I ran a virus scan, spyware, even restored it to to its original settings. Also reinstalled original drivers. I even changed moved it to a different outlet thinking it may be a shortage but no still does it. I have no warranty. Had it just over a year. Nothing goes wrong until now.

Can I use CCleaner to perform a full factory reset?

When I open up CCleaner, there's a tools bar, I click that and then I click Drive Wiper. Under the "Wipe" section it gives me two options it says "Free Space Only" and Entire Drive ( All data will be erased ). I want to know if this is a full factory reset. In another part of it, it says Security: It says Simple Overwrite (1 pass), Advanced Overwrite (3 passes), Complex Overwrite (7 passes)
and Very Complex Overwrite (35 passes). I want to know what they mean and how they work! If I can use CCleaner to run a factory reset please tell me step by step how to. Btw I have a Lenovo T420 Windows 7 Ultimate 64 bit!

Audio Problems with Windows 7 (64-bit)?

My audio is not working on my lenovo G560. When initially starting sound it plays normally for appx. 17-25 seconds then starts skipping for 1 sec or so every ~6 sec. I have checked all updates, re installed all audio drivers and codecs. Ran diagnostics which come up clean and re installed all flash and shock wave players just in case. This happens with all audio (web and system). No problems with video players or anything. Just the audio of all programs ( i.e. Browsers, websites, windows media player, itunes, spotify and system sounds.) What else am i missing that could be the problem?
