Why is my lenovo laptop doing this?

It just started happening recently. I would turn it on and the logo would appear and load, but then it turns black. It keeps doing that. I tried restarting is so many times. The only way I can get it to work is to do system restore. I just got this laptop a few months ago.

Seems that something has fouled up the operating system. First back up everything you want to save and then reinstall the o/s from the hidden partition/drive. Then run the updating routine at least twice.

Take it back to the shop, it's faulty
