Reinstall windows os

The lenovo automatic updates only work if you did not uninstall the Thinkvantage tools that came preloaded. If you did remove them, then you need to go to the Lenovo website to download and reinstall the Lenovo software.

The Ideapad z580 series takes DDR3 SODIMMs, either PC3-8500 (1066 MHz) or PC3-10600 (1333 MHZ)
It can go to 4 GB (2 x 2 GB SODIMMs) in 32 bit or 8 GB (2 x 4GB SODIMMs) with a 64 bit OS. Here is the Kingston page, although they have discontinued these models Memory Discontinued Models

First, try turning on the camera by pressing and holding Fn (second key from the left on the bottom row) and then press Esc (first key on the left of the top row of keys). Release both keys. Many laptops ship without the drivers for the web cam. Go to http://mobilesupport.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-z-series-laptops/ideapad-z580 and download the appropriate driver for your OS.

I hope this helps.

The lenovo line of laptops are in my view one of the better choices to buy, since I never had the pleasure of owning the z580 I can't comment on that particular model.
