This means there can be a hardware issue. I didn't read a word about your monthly cleaning cycle with canned air to the vents. If this was never done then it's time to get a deep cleaning and replace all old heatsink compound.
Also, given the age, I want to read this laptop's Web Speccy report to see the health of the HDD among other things.

I'm looking for some help because I have tons of issues on my pc and it is really frustrating...
first of all my pc specs:
Lenovo ideapad Z500 model 5931
Processor Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
Video Card NVIDIA GeForce GT 645M
Video Card #2 Intel(R) HD Graphics 4000
RAM 8.0 GB
Operating System Microsoft Windows 10 (build 15063), 64-bit.
so lately my pc is freezing randomly.sometimes it recovers and restarts and sometimes it just stays like that and I have to shut it down..also I have noticied a dramatic increace in boot up time..sometimes i have to try for hours and hours just to get the pc to work correctly,because it might turn on but it's extremely slow to the point where i can't even get to the login screen to put my password and get access to desktop.....
I'm ready to do all the manipulations and stuff to get it to work well..at the moment it's working but i'm sure it will freeze and i'll have to go through the living hell like everyday....any help would be highly appreciated
Thanks a lot and sorry for my english.
