desktop auto shutdown and doesn't boot

[skaerz]

I have a Win 8 desktop auto shutdown and doesn't boot with fan spinning very loud. Sometimes, it is OK but after awhile the same thing repeats.

Currently, able to get to safe boot but same thing happens. Wondering what's wrong?
Can't repair...

TS, list down your rig parts like those on the right -->

For your problem, if you got a spare PSU, change it and see if it works.

It is a HP desktop....
PSU seems fine... CPU fan that is spinning loud..

In that case, refer to this link : http://support.hp.com/sg-en/document/c03483233#AbT1

Select "Troubleshooting your HP desktop computer" section.

Refer to this link to get an idea of the Recovery Process : http://bcove.me/z63mrqp2

There is a option to perform file backup before you proceed to do a recovery.

How did you determine whether PSU is ok? Cant you just use another PSU and see if the problem persist?
