Shutdown annoyance

[Test]

Hi all

My computer justs shuts down on its own.
it doesn't give any warning or any messages, it justs shuts down

i have sygate personal firewall installed
spybot and ad-aware are also installed
i checked for spywares and viruses.. there aren't any

a few months back i had the same problem and i changed my power supply.
is it causing overheating? how can i stop it?
i upgraded it to 400 W

any sugesstions?

The power supply itself won't be causing over heating. Inadequate cooling
and overclocking will cause over heating. If your system is over heating,
you should purchase additional case fans and/or a better processor
heatsink/fan combo. Over heating will cause a machine to shut down (if the
motherboard has overheating protection). This protects you from frying your
processor.

It does sound like your computer is over heating or you
had some type of power issue. Do you have a good surge
protector? You might just unplug it and let it sit for 10-
20 sec and then pug it back in and see if it will boot.
but you need to check your systems temperature regularly
if you are having this type of issue.

i upgraded it to 400 W

A 400w power supply should be plenty power to run just
about any PC. Make sure you have plenty of room for air
to move around your computer and check your bios to make
sure you fans are working correctly.

Ah, I see you started this thread earlier, abandoned it, and then posted
again. Silly me - I was answering in the *first* thread. That's why you
should keep posts about one subject in one thread. Anyway, here are
generic hardware troubleshooting steps:

1) open the computer and run it open, cleaning out all dust bunnies and
observing all fans (overheating will cause system freezing); 2) test
the RAM - I like Memtest86 from www.memtest86.com - let the test run
for an extended (like overnight) period of time - unless errors are
seen immediately; 3) test the hard drive with a diagnostic utility from
the mftr.; 4) the power supply may be going bad or be inadequate for
the devices you have in the system; 5) test the motherboard with
something like TuffTest from www.tufftest.com. Testing hardware
failures often involves swapping out suspected parts with known-good
parts. If you can't do the testing yourself and/or are uncomfortable
opening your computer, take the machine to a good local computer repair
shop (not a CompUSA or Best Buy type of store).

Cheers,

Malke

I know you didn't. The OP is someone called "Test". Sorry, I should have
been more careful with my reply and attribution. Either not enough
coffee - or too much! Please accept my apology.

You have something that is crashing - and the system's 'automatically
restart' is cutting in. Turn this off: in Control Panel - System -
Advanced, click Settings in the Startup and Recovery section. There
uncheck 'automatically restart'. You can also usefully change the
'write debugging information' to (none) unless you are actively needing
a dump for debugging something. You may now get a Blue screen failure
instead, but at least will get some guidance as to what is happening
