Distorted blue screen on most startups. Win 10

As the title suggests, I have machine here which 8/10 times will present a distorted blue screen that can't be read, but you can tell it's a stop error with the sad face. I've applied fresh paste to the chipset, GPU and CPU of this all in one Dell build (Inspiron 545) in case it's heat related to no avail.

The weird thing is, there aren't any memory dumps that bluescreenviewer can access. I don't believe any are left when it happens. The whole system just halts and it is logged as kernel power (41) in the event viewer. Any advice would be great. Many thanks.
