Instant Shut Down (LAME!)

[Guest]

My computer instantaneously shut down. No prompt was given. Just Boom.
Off. The light on the main power button would flash with no ability to
reactivate the CPU. Power could be interupted or reset to allow for
rebooting. Computer would last for 30 seconds to a minute before repeating
the shutdown. I've managed to use System Restore to return to a previous
date's settings. That's the only way I've managed to detour the problem. I
now fear to turn off my CPU. Virus Scan, Registry Mechanic, PC Bugdoctor,
Adaware SE, Advanced System Optimizer, and Trojan Hunter have all been
utilized to neutralize and possible infection from outside sources. Any
potential threats are properly dealt with to the extent of my software's
abilities. But, the problem remains. Could it be a mere safety protocol
resulting from some power source complication? Could it be some malicious
program and/or virus infection? Could it even be, on the off chance, a
voodoo hex? I don't know!

Whew! I hope I am understanding that blog of information.

1) Your machine just shuts off without warning??? Can you wait 30
seconds and turn it back on?
2) You use system restore to get around this problem???? Does this fix
this shutting off problem? If it does fix the problem - does it eventually
come back again (if so - how long?)? If it does fix the problem - is this
now fixed and you are wondering what originally happened?
3) Are all your cooling fans working? Have you blown them out with air to
increase circulation? How about your CPU Fan - is it clean and running
properly? Power Supply fan working and cleaned of accumulations of dirt and
lint?

Sounds almost like a power supply problem but let me restate 'almost'. So as
I go back and think about this, do note yr power supply and pay attention to
it, it may be on it's way out....

Yo Bogart,
In answer to your first question, well two... Yes, it just shuts off,
instant power down, no error message or anything. Also, I can't turn it on
after 30 seconds. The light on the power button will steadily blink, but it
does not respond if i push it or hold it or what not.
You see, I'd have to unplug the CPU or switch my surge protector off, turn
it back on, then reboot that way. But, doing it that way, my computer would
log on to windows, load up, but the instant I attempted any program (i.e.
virus scan, or Registry Mechanic) it would just, boom, shut down. Opening in
safe mode and using system restore has been the only way, that I've found, to
bypass this. My computer will then remain on and allow for me to run
programs. If I didn't do this, it would repeatedly shut down and not want to
reactivate to the point where I want to kick something. (not my computer,
because it's brand friggun new, which is also unsettling) Once the system
has been restored, I can use my CPU, that's what I did the first time this
happened. After that I thought the problem was fixed. Then one night I
decided to power down completely for the night, because I usually leave it on
all day. The next day I powered up and it began that crap all over again.
I've restored the system again and haven't even THOUGHT of turning it off
again.
Lastly, I have NOT checked the fans. I will make an effort to do just
that after work today. I may even by a can of duster to blow any of that
crud out of there if that may be the problem. But, over heating after just
switching on after an entire night of being powered down? Lame. Thanks for
the input, any further would be appreciated.

Check your SMPS. Make sure the cooling fans are working @ design
speed. Also check for the CPU's heatsink. As reported by you, this
problem can occur if you have a blowed down capacitor in the SMPS. If
these things work alright and you still happen to face the trouble,
plz let know your complete computer config and what you do after the
system restore that makes your computer go sick.

PS: I also recommend you to check the Event Viewer in Windows XP
Admin Tools section to check for any reported errors by the OS just
before the power off.

If your shiny new TV did something like this what would you do? Take
that sucker back of course. If you or a friend built it then you need to
rethink what you put in it and how secure the connections are. This sure
sounds like a hardware problem, possibly power supply or just way too
much heat. But it could be something silly like a loose power connection.
