still freezes after maintenance

[Guest]

Been working on a computer - did lots of system maintenance (scan disk,
defrag, disk cleanup, Norton and AdAware), but computer is still occasionally
freezing. Tried the Belarc site to check system components (for updating
drivers). Did try to update the chipset (an update to increase speed), but I
don't know if it took. We did not get to try any other driver updates, except
for what showed up on Windows Update. Before that, we had also reinstalled
Windows Xp and done critical updates. Any other ideas of what to check???
I'm not too sure on the chipset driver updates as to what is really
necessary. I noticed some said for advanced users/programmers. Please help.
thank-you. Also, on error checking, when it did show errors, a lot of times
it said the first allocation unit was not valid and then it truncated it.
What is this??

Check for excessive heat. Check for dirty fan blades. Clean all dust from it.
(the fan). Remove cover and blow fan at processor for test or open a window.
etc.

Open your box and point a (household) fan at it.

Check Event Viewer (Start - > Settings -> Control Panel - > Administrative
Tools - > Event Viewer) for possible errors.
