Vista shuts down for no reason

Guest

Please help! I have Windows Ultimate and it is an HTPC (Home Theater PC).
It has three tuners (HDTV Wonder, AverMedia A180, AverMedia 1500 MCE). It
has an HIS 2600 Pro video card.

When watching Vista MCE shows - it will just shutdown - not restart - the PC
actually turns off. The BIOS is set to start up on a power failure - so it
starts back up.

I guess my question is why would my PC just decide to turn off? The CPU is
a Quad core Q6600 - it is not running hot. The PC is home built and is an
Intel DP35DP motherboard.

This has only started recently - this did not happen before. I have no idea
what is causing it. Please help! I have checked the logs - there is nothing
- other than a log event saying the PC did not shut down correctly.

Please help! Thanks

You probably have either an underrated or defective
power supply unit.

The Power supply is new and running at 500 watts. The machine runs cool and
happy - the all of a sudden (and almost every hour between 8-11 PM - very
weird) it shuts down without warning. I hear the CPU fan spin up and then it
shuts down.

I have no idea what happens at that exact moment as thee is nothing in the
logs.

Please help!

A new PSU can be very well defective. Have been know to do that quite often even when running cool. The give away is when the Hard Drive spins up . Spin up of the Hard Drive is the sign when system will shut down.

Also between 8-11 pm is a prime time for power usage and can cause what is
called a brown out (a slight drop in power) this can effect lower quality or
defective power supplies.

I have a Toshiba laptop, an HP desktop and one I built, all with Vista. They all un-expectedly re-start with a blue warning screen that I don't have time to read but the first line says it must shut down.

Did they all do it from new (out of the box)?

Have you installed software on each machine, after which you get the blue
screen?

If you want to read the blue screen click Start, type System, click System,
click System Protection, click Advanced, under Startup And Recovery click
settings, under System Failure uncheck Automatically Restart.
