The previous system shutdown at <time> on ‎<date> was unexpected

Hi everyone.

my first post on here so I hope this is the right sub forum for it.

I have a Sony Vaio laptop that in recent days tends to turn itself off when I am for instance trying to open a large video or convert quicktime to mp4 etc. It turns off randomly, there is no shutdown sequence or BSOD displayed. Just screen goes black and power is turned off.

Laptop is an older model (VPCCW25FG.) 8GB RAM, Samsung 256GB SSD.

Im attaching the dump for some assistance as this problem didn't exist till about a month ago.

Thanks for the assistance.
