Crashing randomly without BSOD

  1. Hi,

    My computer keeps crashing randomly I can just be simply browsing the internet and I have to turn the power off. I think it might be dust as I can sometimes hear the computer make noises but don't really want to open it up. Therefore i'm not really sure where to start. I have defragged and done virus/spyware scans which comes up with nothing. What else can I do to get more to the problem.


    Thanks

    Open your side case panel and tell us where the noise is coming from. This is a simple procedure. We especially want you to listen to see if it is your harddrive making the noise.

    Thanks for the reply. I should have been more specific with the noises, its from the fans as it can be quite then the next minuite it sounds like wind in a storm

    You mentioned that the crashes are random; besides the internet when else do they occur? What OS are you running?

    I'm running Windows 7. It could be anything from playing games to rendering to just leaving the PC and coming back to it frozen

    Thanks

    For diagnostic purposes we want you to run Memtest on your RAM.

    1. Go to www.memtest.org and download the latest ISO version which is 4.20. It is free and perfectly safe.

    2. Burn ISO to a CD.

    3. Place CD in your drive and reboot with CD in drive. (You might have to place your drive as first bootable in your BIOS) The test will take over.


    There is a Tutorial: How to use Memtest in our Guides and Tutorials forum; follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

    Step1 - Let it run for a LONG time. The rule is a minimum of 7 Passes (not hours; this test is not measured by hours); the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.

    There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

    If you have errors you have corrupted memory and it needs to be replaced.

    Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.


    * Get back to us with the results.

    Hi,

    Thanks for the response. I done the test and took an image which is attached.

    Since Memtest shows no errors then find the voltage specs of your RAM and compare it to the voltage setting in your BIOS. Do they match?
