How to Disassemble A Lenovo 3000 C300 All-In-One Desktop?

I need to replace the hard drive into this compute. I can't figure out how to take this thing apart. I unscrewed the screws from the back of the monitor I have tried to pry it open but I do not want to chip or bend the plastic or damage it. There has to be a simple way to do this. Any help would be greatly appreciated. Thank you!

NOTE: I have tried to look up guides on google and Lenovo.com, but the maintenance manual i found only gives instructions about how to replace the keyboard, mouse or power cable (dooh, just unplugging them)

My Lenovo laptop won't load the desktop after I log in?

My laptop was completely fine the other day, then when I turn it back on the same day, after I log in, when the desktop screen is meant to load, I get black screen and a cursor (I can move the cursor) instead. If I press Ctrl+Alt+Delete I can open the Task Manager and Shutdown and Sign Out and all that, but I just can't do anything?!

The longest I've left it on is about 15 minutes, but still nothing loads. I've tried all I can think of (pressing F5 and F8 and all that / restarting) but nothing happens.

I'm not too sure what to do, and I really need it fixed As soon as possible as it has a lot of work on it that need.

Can't connect bluetooth headset to Win7 (64-bit)?

Can't connect bluetooth headset to Win7 (64-bit)?

Added (1). The headset is an Ausdom M04, and I know there's nothing wrong with the headphones, because they connect to my desktop and my Galaxy. The problem lies in my Lenovo Y410P laptop, and I can't seem to figure out the problem. THE DEVICE WILL PAIR, BUT WILL NOT CONNECT. I tried going to sound, and the headset shows up disconnected. When I right click and click connect, nothing happens. I did however notice that I could not find the "Bluetooth Suite", but could find "Bluetooth File Transfer".

Do I need to uninstall MacAfee before I install Norton?

I bought a laptop a few months ago and it came with a month of MacAfee protection. The MacAfee was already installed (the icon was already on the desktop home). And I subscribe to the 30 day trial bc I had no protection for this pc. But I just bought a 1 year protection Norton (disc. It needs to be installed). But I was told that I MIGHT need to uninstall the MacAfee before I install the Norton. What should I do? I don't know how to uninstall anything. So please provide me with steps. Also, I would like to uninstall MacAfee bc I won't ever be using it so it just takes up space. The laptop is a Lenovo y50 windows 8

Will this graphics card work in my pc?

I just recently purchased a desktop pc from lenovo that came with a gtx 750 graphics card. My pc only has a 260w power supply but both the gtx 750 and gtx 750 ti require a 300w supply. The 750 works fine right now but I was wondering if I could switch out the 750 for the bit more powerful 750ti and be fine. They both require the same amount of power.
