System crashing from few days but memtest fine. (HP Probook 4510s)

Hello,

From past 3-4 days or so my system freezes randomly.

Last it was up good amount of time was for 11hrs on December 31st.

Then on 1st it crashed 2-3 times.
Then on 2nd it crashed twice but then remained up 11hrs.
On 3rd I did not use it much (Sunday)
On 4th it crashed 4-5 times sometimes in 30mins - sometimes after 3hrs.
Today it crashed 1 time too.

I have been running Arch from about 2 yrs now on this laptop: (laptop is atleast 4-5yrs old)

HP Probook 4510s
Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller
Intel(R) Core(TM)2 Duo CPU     T6570  @ 2.10GHz, 1600 MHz
4GB RAM

Arch is up to date EXCEPT thatt Kernel I am using is:
Linux xxx 3.17.6-1-ARCH #1 SMP PREEMPT Sun Dec 7 23:43:32 UTC 2014 x86_64 GNU/Linux

I am using old kernel because after kernel 3.17 there is CPU FAN bug introduced for few HP laptops and it is still not resolved.

But this kernel is working fine from long, otherwise

I am not sure if this has any relation to new C++ ABI changes? Or qt5 / kde related? or X related?
Or something that this old kernel is no more compatible with.

I memtest-ed the laptop. It passed memtest twice. So memory seems to be fine.

journalctl shows nothing at the time of crash.

Sometimes its a complete freeze
Sometimes mouse moves but nothing happens on clicking or Alt-tabbing.
Nothing happens on ctrl-alt-f2 either.

When its not complete freeze - I can ssh into system from my mobile (but it freezes after 2-3mins or less)

In short, there is no exact reason for crash that cud be detected.

Anyone has any clue?

Thanks in advance.

Re: System crashing from few days but memtest fine. (HP Probook 4510s)

I wish you were not running an ancient kernel.   Have you installed and configured the mirocode updates for Intel?  Does that even work for pre-4.X kernels?
Are there any messages in your journal about disk I/O errors?  About GPU problems?
What is the output of free   ?
