Windows 10 takes a long time to do any task!

I have a Lenovo z510 Laptop with 6GB of DDR3 RAM and 1TB of HDD and 8 Logical cores of a Core i7 4702MQ CPU processing at 3GHz ...
I don't say that it is a high end system(and it is not!) but neither I think that it is a Low End or even Low Mid one!
So...do you think that it must take about 2 minutes to boot and then about 10 seconds to run Chrome for first time...3 or 4 seconds for Start menu to load the first time I click on it and EVEN sometimes having lags on loading start menu after using the windows for a while?!
The problems doesn't go to end here! :
Sometimes I can not use Cortana until I restart the windows!
Sometimes the apps take a long time to load
and other things like this...

and now...my questions:
1.is the problem with my hard drive?!
if it is...is it normal with all HDDs or there must be a problem here???
2.I am using more than 50% of my HDD...is it a lot??can it cause the problem???
3.I am planning to add a 128GB of SSD to my laptop...do you think that it is a good idea??

*in addition: I have just reset my Windows(somehow reinstalling) for a week to see if it changes anything...it has changed but not that much...and from all large programs,I only have PES 2016,Photoshop,Visual Studio and Office... I am planning to install Premiere,Assasins creed Syndicate,etc. and I don't know what will happen then!I think that my PC will not start!

HELP ME PLZ

Hi, suggest a process of elimination.
1. Previously have you seen significantly faster response times?
2. Can you run chkdsk from an elevated command prompt (Windows key + x, click Command Prompt (admin) & report result
3. What are the SMART params of your disk?
4. Try a clean boot, and compare the times.
How to perform a Clean boot in Windows 10 - TechNet Articles - United States (English) - TechNet Wiki

(Note you need to reverse the settings to get back to normal boot)
5. If no change, try Safe Mode and compare response times.
6. Please post screenshots of your task manager - organised by highest CPU, highest RAM usage.
7. Cortana - puzzling- at least it's not completely broken.

Given that we may have some better idea- thanks.

SSD: My - new- PC is i3 dual core, but 256Gb SSD + HDD- start menu is instantaneous, explorer maybe 0.3s. About 12s to lock screen. I have a lot of programs installed.

Comparison with my 6 year old laptop from which I moved using disk images and Laplink - about 3 hours processing to reproduce my working environment, settings, and installed programs, so much is identical- say 90s to 2 mins to lock screen.

HDD usage: I don't know what partitions you have.. hope you have some.. to separate data from the OS. Basically Windows needs enough free space for paging file (and of course for updates- especially with Win 10, for Windows.old too. You need to beware of programs that take up loads of space on your OS partition or disk in library folders, and of course your own personal data.

I never put my personal data in the 'normal' Documents, Videos, Photos etc library folders- it's all on a separate partition, so separate from the OS.

When you move to your SSD, you need to consider how to lay out your personal data and the folders used by your programs, so your SSD doesn't fill up. Think what you need to run fast- and often- and what not. Slower and infrequently accessed stuff you want to back up goes on your HDD.

If your current OS, programs and data are all combined at present, you need to plan how to transition to an SSD rather carefully.

Thanks for your fast response :)
I have questions before performing what you asked me to do!
1.What are SMART parameters and where can I find them?!
2.How should I reserve the settings to get back to normal boot?!
3. and if I'm supposed to disable all services -included Microsoft services- doesn't that make my PC to malfunction???

There are several programs that will show you SMART parameters (hd tune, Piriform's Defraggler)...

Hi, A clean boot is a method MS has supported thru generations of Windows. Nothing new...

It simply reduces the number of programs and services running bringing your PC closer to when you had nothing installed ( but not as far as that e.g. drivers still active). This is to try to identify possible conflicting things the user has added. Unfortunately, MS has arranged it so there's a lot of clicking involved- even more awkward in Win 10!

You may prefer to simply select Diagnostic boot in msconfig - Windows key + R, enter msconfig
Click Diagnostic boot.

Otherwise please read the guide on clean boot- you will note MS services aren't touched, a good point.

A search tool is your best friend.
Here's how to do a clean boot:

You may prefer to set a restore point before you set up the clean boot, and use the restore point to reset everything back as it was.
If unfamiliar with System Restore, searching will help you.
Note that System Restore is OFF by default in Win 10- so if you've not turned it on, you would need to.
This is entirely optional.

I don't see so much difference between clean boot and normal boot as maybe the clean one took even more time!
but I just took some screenshots from HD Tune Results which are making me worried about my HDD's health.
it would be a pleasure if you take a look at them:

Should I use my warranty as I still have one month left???
Is it really a problem that the HD tunes shows some parts of my hard are damaged?!
Thanks!
