Computer freezing and randomly shutting down. Please help

Hi this is my first post on this forum and i hope im posting in the right place. For the past 3 weeks my computer has had me so frustrated i dont know what to do. First off it started off just randomly powering off. Which got worse and worse. So we took it apart and made sure everything was clean and dust free etc. Now its not powering off as much but its freezing. Freezing alot. When it freezes you cant do anything. No cntl alt delete, you cant even move the mouse. Its like complete freeze. Also everytime it freezes when i try to restart the computer it hangs in bios about 5 times until finally after restarting it 5 more times i can make it back into windows. It keeps doing it and i have tried almost everything i can think of. I know its not overheating because i have been checking the tempurture of everything on the computer everyday. Everything is running super cool. I have no idea what is wrong please help.

The computer is -

  1. psu?
    have you tried upping the memory voltages?
  2. I know that is an option But the thing is i dont know how. Also when i go into my bios and look at the area where you could change the memory voltage it is greyed out and wont let me change it
  3. Would really be happy if one of you smart guys would help a poor girl who doesnt understand computers out
  4. some motherboard will have a switch on the board itself that will let you start overclocking, read over your manual

    in bios look at your hardware monitor, check the temps are good

    is your power supply strong enough for your config?
  5. All the temps are fine and the power supply is a 650w. However i lost the manual
  6. *not convinced you are a girl*

    If you can get an (older) ubuntu CD, you can run memtest86+. If that is the problem, you'll likely get errors in a pass or two. In theory, you should run it overnight.

    If it locks up DURING the test, it could be motherboard, ram, or psu. Possibly even processor.

    I think memory or PSU are most likely culprits. Can you try 1 stick of memory at a time?

    Do you have on-board video? You could eliminate that as a possibility by removing the add-in card or disabling on-board in BIOS if it isn't already.

    Additionally, I'd disable the page file with 8GB of ram. Probably even 4. Some may disagree.
  7. what do you mean by page file?
  8. First things to check with this is the power supply and RAM. Try running with one stick of RAM at a time, see if it boots OK, and what sticks cause issues. If all of your RAM does the same thing, try a different power supply.
  9. bumping my thread on here, same issues! same solution maybe? :O

    Keep things in your thread or don't even start a new one. If you think it may be the same solution, did you try what was posted here?
