I have Windows XP Home and SP2 installed. Also I have AdAware, Spybot,
Search and Destroy, MacAfee virsusscan and MS AntySpyware...
Yesterday and today, I noticed that several icons on my desktop
changed to a generic white square... Even as I'm writing this message,
two more changed... What's going on? How to stop icons from changing?
Are you the same person with all the problems on the eMachine? If this
is the same machine, I would say you have some hardware failures. Here
are general hardware troubleshooting steps, but from your other posts
(if you are the same person), I would say your best bet is to take the
machine to a professional computer repair shop (not your local
equivalent of BigStoreUSA). I don't say this to hurt your feelings, but
someone who doesn't know how to check if the hard drive shows up in the
BIOS is going to have a tough time doing hardware troubleshooting.
1) Open the computer and run it open, cleaning out all dust bunnies and
observing all fans (overheating will cause system freezing). Obviously
you can't do this with a laptop, but you can hear if the fan is running
and feel if the laptop is getting too hot.
2) Test the RAM - I like Memtest86+ from
www.memtest.org. Obviously, you
have to get the program from a working machine. You will either
download the precompiled Windows binary to make a bootable floppy or
the .iso to make a bootable cd. If you want to use the latter, you'll
need to have third-party burning software on the machine where you
download the file - XP's built-in burning capability won't do the job.
In either case, boot with the media you made. The test will run
immediately. Let the test run for an extended period of time - unless
errors are seen immediately. If you get any errors, replace the RAM.
3) Test the hard drive with a diagnostic utility from the mftr. Usually
you will download the file and make a bootable floppy with it. Boot
with the media and do a thorough test. If the drive has physical
errors, replace it.
4) The power supply may be going bad or be inadequate for the devices
you have in the system. The adequacy issue doesn't really apply to a
laptop, although of course the power
supply can be faulty.
5) Test the motherboard with something like TuffTest from
www.tufftest.com. Sometimes this is useful, and sometimes it isn't.
