I have been having some troubles with this laptop even when I first purchased it. It sometimes crashes whenever I turn it on so I usually have to restart the PC. I don't use up much RAM or storage as I always check what programs I can uninstall. The PC is usually fast but sometimes it just crashes whenever I boot it up. Its not a massive problem but I do want to a great working laptop.
Added (1). My PC supports Windows 8.
If this issue started when you first got it, you may have a bad "image" of the actual operating system. Best bet is if you still can return it, do so and get a replacement.
If this is not an option, see if you can restore your computer to the original factory settings (will wipe out any files you have created, etc so you will need to back them up if you want to keep them).
If you still have issues at that point, you are stuck unless you put a new operating system on it.
