Toshiba Satellite C55-B

I am trying to trouble shoot for an NGOs laptop, which is a Toshiba Satellite C55-B.  I attach herewith the file giving the specs of this laptop.   When it boots up, it gives all sorts of errors, like disk errors, and with lots of garbage.  From previous experience on my pc, thus I ran the command from the desktop, a scan command.  I attach here also the results of the scan.  Also attached is the log file that the scan command produced.
Can the experts please let me know what is wrong and how to fix them.  The laptop was bought in Nov 2014, and I wonder if it is still under warranty or some sort of warranty that I can get free technical support.  If Yes, and i u have the number handy, please let me know.  thank u.

First run the disk manufacturer's diagnostic utility on the disk. If it finds errors, replace it. You'll find most of them on the UBCD, along with memtest86+ which you should also run to make sure the RAM is fine:

If the disk is 100% OK, run a chkdsk /f /r on every partition from an elevated CMD prompt.

In response to rindi, please let me know where and what is the name of this diagnostic utility.  Thank u.
The tools are included on the iso file you download from the link above. Just use your CD burning tool to burn the iso to CD, then boot the PC from that CD. There is a menu system from which you select the tool you want to run.
i also recommend UBCD  - to test RAM and DISK
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)                        ultimate boot cd             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems :
