Vista System Lock Up

[Guest]

This is another post about Vista lock-ups, however, this has a bit more
information and detail.

My system will lock up under two different situations outlined below. I am
running Vista 64bit Ultimate on an AMD Dual-Core with 2GB Ram, NVidia 7900GT
with most currently available drivers (check regularly) and RealTek Hi-Def
Audio Codec.

First lock up is during intense gaming, usually network gaming like WoW,
LoTRO or Shadowrun. In this situation over some play time, my mouse will
intermittently stop working. It is a USB Logitech Mouse. If I don't notice
it, say using keyboard shortcuts, I will hear some sound stuttering, then the
sound will get stuck on the last note and the whole system will just stop.
There will be no BSOD, nothing. The last screen will just freeze, the sound
will play and the whole system will not respond.

I have no option other than reboot. If I hit the reset switch at this time,
the system will not return, have to power off, wait and power back on.
Sometimes I can go a whole evening before this happens, sometimes it will be
the first 10 minutes of game time. I have checked my IRQ settings, since it
appears to be some type of hardware contention, and I have disabled all
extraneous hardware in my BIOS, secondary network card, FDD and such that I
am not using. This offsets the issue for awhile, but it always returns.

The second lock-up happens overnight. If I leave my PC on overnight, it
will always be unresponsive in the morning. I have disabled Power
Management, including monitor shut off, so that only the screen saver is
running. When I check it, the screen saver, like the first issue, is just
stuck and I have to power off the system and restart.

I have reformatted my HDD once and reinstalled Vista on it, and that did not
help, I am upgrading my drivers every time I find a new one out there, and
they may slow down the freeze, but doesn't stop it.

Even though you appear to have enough recourses ie Ram you did not say what
processor you have, It appears a resource failure. You could check in
Control Panel/Performance Info

That's a tough one to isolate.

It sounds to me like you might possibly have a defective motherboard. I just
replaced my Asus M2NPV-VM MB which was exhibiting similar problems.
I have had no problems since.

Secondly...it might also be a defective power supply. That will do weird things
to your system. Have you got another one you can try ?

Also possibly a heat issue..case temperature or video card temperature.

Also possibly an application failure..memory leak ?

Might be worth a few bucks to take it down to your local computer shop
and get it bench tested.
