Viao shuts down (power off) after 1 min use - help

[odiervr]

Morning all,

My wife's Sony Viao (i3, 4 gb, 1 year old, win 8 upgraded to win 8.1) powers on fine. Windows starts normally (no virus stuff that I can see) but then ... after 1-2 minutes it just dies. Power's off. Not a windows is shutting down - this is black screen - there is no power shutoff.

If this were a desktop i'd be thinking PSU.

No significant drop / new software ...

I've built 3 desktops and have used PC's since 97. Can a laptop PSU go bad in a year ?
Other thoughts: Can this be a sony driver's / win 8.1 issue ?
Thanks for any help / thoughts ? dan

I doubt it's laptop PSU related, I'm going to guess (as it hasn't been stated) that the battery is trashed which is causing false readings. Try removing the battery and running it purely of the PSU alone and see what happens.

will give it a try w/o the battery when i get home. Thanks !!

Same problem with the battery removed. Any other guesses ?

Can you hear the fan spinning? If not, the CPU's safety feature kicks in and powers off instantly. You can also verify if the RAM is well placed into the slots.

This is because your fan is not spinning. Try to see if any particles are obstructing the air vents.

V1ctor and Marwan. You are both corrrect. The fan is not spinning. Nothing is blocking the exhaust air. What do i do now ?
