startup freeze on Compaq PC and dust

Discussion in 'Computer Support' started by Steven Chipman, Nov 30, 2005.

  1. I had run my Compaq PC (Presario 6415cl) unattended during the day but
    noticed a problem when I tried to use it early afternoon. What happened
    is that I shut down and restarted the machine so it would work better
    after running so long. However, all that appeared on the screen during
    restart was the Compaq welcome screen (not XP) and it froze there and no
    keyboard input could budge it. After 2 more attempts, I decided to
    complete disconnect everything hooked to the computer, including the
    power cord and let it sit for a bit. As I let it sit, I happened to
    notice dust in the lower half of the unit when it vents. Immediately it
    dawned on me that I had let dust bluid up in the unit and I proceeded to
    carefully to take apart the unit to clean it up. Sure enough, there
    was dust nearly everywhere and I vacuumed and manually removed what dust
    I could. Afterward, with the unit put together and all connections
    hooked up, I restarted the unit and it worked normal. Also, I have to
    mention that I had a couple of "Blue Screen" warnings that shut down the
    unit nearly a week ago (in hindsight, maybe a first warning of the

    What I am wondering if there are other things I need to do (beside
    getting a lot more active in keeping my unit clean) or watch to prevent
    this from happening again?

  2. I've had the same experience lately with a machine that sits on the
    floor. Started getting blue screens, did a check and a lot of the little
    vents were stopped up with dust. Cleaned the machine out, no more blue
    screens. You should also make sure any cooling fans are running
    correctly. Quite a few of the machines I see have one or two failed fans
    but the customer doesn't realize it because another fan is running
    making it sound normal. Keeping drivers updated is usually a good idea.
    All the normal "safe computing" warnings apply: keep antivirus and
    antispyware up to date, etc, etc.

  3. Would installing replacement fans be something I could do myself or is
    it advisible to get a professional to deal with it?

  4. They're easy to replace. You can find them at computer stores or online.
    The most important one is the CPU fan, make sure you get one that's
    suitable for your cpu.

    It's not a good idea to use a vacuum to clean a computer. Vacuum hose
    ends can build up static electricity that can fry sensitive components.
    Better to take the system outside and clean it with a can of
    compressed air.
