Have scanned with all programs. No spyware or adware found. However, cannot
get through a complete AVG scan. Only about 30 minutes (no virus found up to
that point) and then the system shutdowns and restarts once and again, not
getting to "Welcome". Second time boots O.K. Here's Event View Log: Details

Explanation
The system BIOS attempted to incorrectly access hardware resources
concurrently with the operating system. This type of access cannot be
synchronized and can cause system instability.

I have update the BIOS as instructed, but the problem persists as stated
above.

Any help will be appreciated.

P.S. Since installing the BIOS update, HDD indicator has stopped flashing. It only shows briefly at startup.

Are you using the system while the AV scan is running, or do you just walk
away and let it run?

Could be trying to "sleep" at 30 minutes and failing.

Just a couple of ideas....Defender installs a new restore point each time
you start your computer. It can be disabled from doing that in
Msconfig/start.... also why not try to start without AVG doing a scan...or
do a virus scan with another programme!! I only scan about once every two
weeks although I update daily! As with other suggestions, if it works you
can then then look more closely at the offending programme.

Sounds like something is setup incorrectly in windows or the BIOS it's self.

Set the BIOS back to it's original settings (some BIOSs have a "optimised"
setting and a "default" or "compatable" setting. Try both).

Try disabling or changing some of the settings in the BIOS such as the power
saving, and check the temperature monitor (some systems are set to shutdown
if the system reaches a certain temperature) I'd make sure you know what your
doing here and/or how to reset the BIOS if you stuff it up.

The other thing to try is downloading all the drivers you can find for your
computers components (chipset/motherboard, LAN, Graphics, etc). Windows may
have an incompatible driver which is dealing with the system's hardware
incorrectly. The only other thing would be to disable all of Window's power
saving settings to see if these are the culprit (start->control pannel->Power
Options - Set everything to "NEVER").

The only other thing I can think is that something is corrupt in your
windows install and you need to reinstall and/or repair the installation.
I'm sure there are many tricky ways to avoid this but you need to know what
your doing and probably have a good Idea how to figure out EXACTLY whats
wrong.

I'm just letting it run.

AVG doesn't scan on startup. Only when I start a scan manually, which is not
more than every 2 weeks or more.

All the power options were on "Never" when the latest shutdown/restart
occurred. On an occasion or two, 'screen saver' was 'On'.

I'm not sure how to treat the BIOS. But I'll have a look at it and if it
isn't clear, I'll contact the vendor, HP.
