For now we won't worry about the hard drive test.
Using your model number, it does not look like you have a "pointing stick" which makes it more rare that a touchpad will have issues but it does still happen.
Let's try to test that keyboard and mouse (buttons) using: http://www.passmark.com/products/keytest.htm
Click the "Download now" link and install the software, open the program and click continue (free for 30 days). Then you can see what key presses and mouse presses happen. Maybe we can locate the problem using this. The keys that are pressed should light up or become colored in the program. If you do not press a key and it becomes highlighted, we can assume that key is "pressing" on it's own.
That software reports the same as speccy, you have 2 uncorrectable blocks and 2 pending blocks. These are considered critical SMART errors. Due to these issues, I would recommend frequent backups of important data to another storage device if you wish to continue using this hard drive. Drives with critical SMART errors have a much higher failure rate than those which have no errors. The other option would be replacing the hard drive which IMO is the best choice if you wish to continue using the computer. Drives with bad blocks may cause a computer to freeze, have file corruptions, fail to install software, BSOD etc. I will say before worrying about this, we should get to the bottom of your random clicking / mouse movement issue which may or may not be related to the drive.
We can get around a hard drive or OS related issue by using a CD/DVD or USB bootable version of linux. I generally use Mint: http://www.linuxmint.com/download.php
Cinnamon 32-bit 64-bit An edition featuring the Cinnamon desktop
You can use either version 32 or 64.
Basically download Linux Mint, burn it to a disc or create a bootable flash drive and boot to linux instead of windows.
If all of the same random clicking issues and freezing happen in linux, we can say without a doubt it is hardware related.
