Haven't been here in a while, but what's up everybody?

My uncle has a problem with his computer.

Here's how it goes:

1) Turn on computer
2) Tower/fan is really, really loud after turning on (imagine race car engine)
3) Use computer for 15-30 minutes (browsing, etc.)
4) Computer randomly shuts off (no BSOD)

- I checked and there's no Minidump file
- I got rid of all the ads/spyware on his computer

Still, the computer turns off. Any help?


Thanks a lot. Will post whatever logs you need me to post.

It sounds like the PSU fan. Have you checked to see if the fan in the back of the PSU is turning?
Turn the system on and listen to the PSu from the back of the system. Is the fan turning and is the sound coming from it?
Is this a desktop system or a laptop?
If a desktop have you opened it up and checked the inside for dust bunnies?
Check all the fans to make sure they are turning or are clogged up.

^ Yep, the fan is indeed running.

The computer hasn't turned off yet (since 1.5 hours ago). I'm using it as we speak, and everything seems to be running fine.


Hmm..

How is the noise level?
Let's take a look at some things if you will please.

Download Speedfan (The download link is to the right), and install it. Once it's installed, run the program and post here the information it shows.
The information I want you to post is the stuff that is circled in the example picture I have attached.
To make sure we are getting all the correct information it would help us if you were to attach a screenshot like the one below of your Speedfan results.

To do a screenshot please have click on your Print Screen on your keyboard.
  • It is normally the key above your number pad between the F12 key and the Scroll Lock key
  • Now go to Start and then to All Programs
  • Scroll to Accessories and then click on Paint
  • In the Empty White Area click and hold the CTRL key and then click the V
  • Go to the File option at the top and click on Save as
  • Save as file type JPEG and save it to your Desktop
  • Attach it to your next reply
