Dell Precision M4400 shuts down randomly by itself

[brsmith4]

My Dell Precision M4400 has been running fine except for one thing - the automatic shutdowns. Usually, the shutdowns are caused by general use - the most strenuous thing I use my laptop for is Netflix. I thought it was the heat of the GPU that was causing it, so I cleaned it (dropping the average temp from 65 degrees to about 50), and it's done nothing to solve the problem.

There's no error message indicating an overheat (or much of anything, actually) - usually, when it shuts down, the monitor shuts off (but the lights on the actual computer itself are still on), then the system shuts off, and it usually takes a few times to reboot it. Does anyone have any idea what is wrong with my computer?

Bad video card is very likely, did you try different RAM or testing with one ram stick at a time? You can look in the event log for application crashes that may cause this.
