WinXP hang or restart after NAV2005 liveupdate

[wcle...@gmail.com]

Everytime after I carry out a liveupdate for my Norton Antivirus 2005
(bundled with Google Pack), my WinXP Pro SP2 will soon hang up or
suddenly restart.

Since it is an abnormal shutdown, Windows will automatically carry out
a chkdsk before starting up. Usually, but not always, Windows will find
some liveupdate-related files corrupted, and then fix them (delete
them? or restore them to a previous image? I don't know).

After the fixing, it seems that the virus definition was not updated,
because the virus-definition-expired warning still pops up.

Due to this problem, I formatted my C: drive and reinstalled Windows.
However, the problem persisted.

Is my PC infected with a persistent virus? Or is it caused by hardware
failure?

Now my PC can hardly boot up. 9 out of 10 times it hangs up at the
first screen during memory checking:

(note that even the memory counter cannot be properly displayed. The
digit 3 is fragmentary)

Seems it is indeed a hardware failure, and NAV's liveupdate
coincidently hit the problem.

But which hardware is more likely the cause? RAM? Motherboard?
Harddisk? Can anyone familiar with liveupdate, or familiar with
hardware give me some clue.....?

I don't think that problem is connected with LiveUpdate. You aren't
getting past the memory tests so it's purely a hardware problem. Do you
have any program that will test hardware components?
