Faulty RAM can lead to boot problems. Remove and reseat the RAM modules or try using different RAM sticks to determine if this is the issue.

Outdated or incompatible graphics drivers can cause screen problems. Visit Lenovo's official website to download and install the latest drivers for your laptop.
