Terrible Issue

[Sully91]

Well im not sure what exactly is wrong... Ive narrowed it down to my processor and Motherboard but not really sure which is at fault.. Basically my computer keeps shutting down randomly... However, if I leave it alone with no programs running it wont shut down ever... But the second I pull up say, internet explorer or anything really give it 5-10 minutes and power off... Ive check to make sure all my fans are working, ive checked to see if anything is overheating.. and well nothing.. The weird thing is tho.. that every once and awhile my USB ports wont work.. So thats why I havent ruled out my motherboard... Any help guys I really don't wanna waste my money taking it to someone to run tests..

Download, and install SpeedFan: http://www.almico.com/sfdownload.php
Post your computer temperatures:



Provide processor info (hold Windows logo key, and hit Pause/Break key to find out).

yes get speed fan and post the results from that page Broni showed you, its most likely that your CPU heatsink isnt cooling down the processor enough. when the processor reaches a certain temparature it shuts the computer off to reduce damage done to the system, dont worry its a fairly simple and low cost repair if it is the heatsink

Ok

Computer Info..
  Pentium(R) Dual-Core CPU
  E5200 @ 2.50GHz
  2.50 GHz, 2.00 GB of Ram

Temps.                   Temp1: 44C
                              Temp2: 41C
                               Temp3: 23C

                               Core 1: 42C
the temps seem to stay the same the entire time.

even when running those programmes?

Since your temps seem okay, and your USB ports intermittently crap out, then it's not unlikely that your motherboard could be the problem.

The next thing I would check before the motherboard, however, is your power supply.  If your power supply is on the fritz or if it's just giving enough juice to run your computer and little else, then weird things like your USB ports malfunctioning can happen (especially if you're using a bus-powered device like some external hard drives).  The moment something draws more power than your power supply can muster, your PC will shut down.

So if you have a spare power supply that's decent, try that out.

I just purchased a new power supply thats 650 watts... But here is the weird thing, sense I downloaded speedfan... My computer hasnt shut off at all!... could it be possible that there was a error reading the temp of my cpu and thats what was shutting it down?

Maybe the CPU fan isn't running when it's supposed to, or it's not attached properly, or it's full of dust, or needs reapplication of thermal paste.

Well I did just put thremal grease on again.. but it shut down after I did that.. Other than that I havent touched anything im not sure why its working all of a sudden
