    Hi guys,

    I'm just a newbie and don't know how to mess inside my PC.

    I just want to ask what problem my PC might have. My PC is old, but it is the only one I have. Lately, after some time of using my PC, the graphics went crazy with big pixels and the resolution was messed up. When I tried to print, the output has gone crazy as well. Then all of a sudden my PC shut off. When I tried to restart, it shut off again immediately.Today, as I tried to start again, everything seemed to be fine, but again after hours of using the PC shut off again. I worried that I might be hurting my PC since the problem still persists.

    Fans are working.

    Specs

    Pentium 4 (2.8 Ghz)
    1.5 GB DDR1 RAM
    320GB SATA HD
    Board: FOXCONN 865A01
    Bus Clock: 133 megahertz
    OS: Windows XP Professional Service Pack 2 (build 2600)

    I really need my PC for my upcoming school finals and projects. I'm desperate, please help.

    It sounds like its overheating for some reason or a power supply problem or the motherboard is going.It might be that if its a desktop it might need cleaned out of dust and dirt.If its an old computer it might just be wearing out.Btw sp 2 is no longer supported. You need to find out exactly what the problem is and go from there and see if its even worth fixing first.

    Thanks much SUEOHIO. Do you think its from motherboard? I have already replaced my motherboard before. I just bought it in January this year. At this instant I'm replying to you, my PC works just fine.

    It could possibly be a faulty motherboard but other things also.I would have it checked out so you will know what the exact problem really is.You are welcome.

    Go here and click the green "Download latest version" link to download and save

    HiJackThis 2.0.4

    After it's been downloaded and saved, close all open windows first, then

    double-click the saved file to install it.

    Allow it to install in its default location - C:\Program Files.

    After it's been installed, start it and allow its main window to load.

    Uncheck "Do not show this window when I start HiJackThis".

    Click "Do a system scan and save a log file".

    When the scan is finished in 30 - 60 seconds, a log file will appear.

    Save that log file.

    Return here to your thread, then copy-and-paste the entire log file here.

    ---------------------------------------------------------------

    Start HiJackThis.

    Click on the "Open The Misc Tools Section" button.

    Click on the "Open Uninstall Manager" button.

    Click on the "Save List" button.

    Save the "uninstall_list.txt" file somewhere.

    It'll then open in Notepad.

    Return here to your thread, then copy-and-paste the entire file here.

    I don't mean to butt in, here, but the next time you witness your computer shutting off suddenly, could you go into the BIOS and look at the temperature? Just let it sit there in BIOS for a little bit and watch the CPU temperature. That will help to narrow down the possibilities.

    I used to have a desktop computer that ran extremely hot and would suddenly shut down at times. Another thing you can try is a free program called SpeedFan. It will allow you to track the temperature of not only the CPU but also the chipset and the video card.

    If that desktop is old and the case hasn't been open in a year or two, there's a good chance that the interior is loaded with dust, hair, etc. and needs a good blowing out.

    A dirty interior will definitely contribute to overheating problems.
