Before swapping out the kernel, you might try to determine the part of the
system causing the crash. Have you tried booting from a pristine Trusty
image (USB stick or CD) and seeing if it crashes then?

Here's one list of suggestions for tackling system crashes:
https://help.ubuntu.com/community/DebuggingSystemCrash

After ruling out a memory issue I believe you can also rule out problems
with kernel modules by rebooting in "recovery mode" and seeing if the
problem goes away. Of course the system might not be very functional in
recovery mode, but if you have been able to get it to crash when doing
particular activities this might help isolate it.

Of course if the crashes seem random all of this becomes pretty difficult.

You might also look in the various log files such as /var/log/syslog or
/var/log/dmesg or even ~/.xsession-errors and see if you can see some
entries that seem to occur just before the crashes.
