Windows 10: Combination of problems

Hi Ken, my laptop basically works now.
Let me just confirm steps I took, so we are on the same page
- Took HDD and connected it to friend's desktop
- made my hdd primary device. removed login password, cut/paste documents/desktop/download folders to my backup hdd; unchecked "allow this device to turn off PC" option in Device Manager for all USB Root Hubs (saw this online somewhere as USB solution)
- made my hdd secondary device, and did a disc check + bad sectors scan and repair
- took hdd home, did memtest

My PC works now, touchpad didn't reboot the machine either, but still it's buggy - driver issue I guess, so I deinstalled it from device manager just in case. USBs work too.
Prior to touchpad/usb issue I got reboots while playing game and/or doing some heavy work. Thought it's cuz of the temperature issue.
I guess all of this may be caused cuz of HDD failing?
Not sure whether ssd is better investment rather than buying new pc


EDIT: it just rebooted itself while browsing

 

Good news.

Given heat issues (possibly) unless you are prepared to open up with some extensive work then I would be looking new PC.

You may even need to remove and redo thermal paste. You could always get quote at shop to do work but you will be in for some real money.

As to touchpad, find out what your device shipped with so you can locate proper / best driver.

SSD really makes a big difference but if the foundation is shaky then you won't be happy.

Yo could look at HWMonitor to monitor heat.

You could also look at Driver Verify.

This tutorial will guide you through the verification process, heed the warnings. Assuming it fails follow the posting instruction in the BSOD section of forum.

Taken just after PC rebooted on his own again, didn't wait for it to cool off or anything.
Under the "Clocks" section core #0 and core#1 change all the time from 1.1k to 2k, not sure if it's normal so I mentioned it.

Thermal paste change and cleaning is not pricey here, ~ $10.
But I ain't sure that and ssd (~100$ for some decent 240gb Kingston one) will fix all my problems?

 

It looks to be running hot.

Guess when I said pricey, someone has to tear it down and rebuild and when they tear it down what do they find?

I threw an SSD in a machine built for XP. Runs really nice but I wasn't dealing with an unknown problem.

The nice thing about SSD, you can always reuse.

 

Playing game goes almost to 100C

Not sure whether it reboots my pc at 100C
Thanks a lot m8, think I know how to proceed from this point
