Brief spec.
P4C800 rev. 1.03. P3 3.4Ghz cpu. 560W Thermaltake PSU.
1 Gb (2x 512mb) Corsair ram. Nvidia Geforce 6800 Ultra graphics.
Win XP Pro SP2 with all updates.
No other cards fitted. Not OC'd.
On-board sound disabled. On-board lan enabled.
Boots to desktop then immediately shuts down completely.
No changes to soft/hard ware in last 3 months since when it
has run perfectly 24/7.
It will boot into safe mode and has been running stable for the
last 10 hours. Any ideas what the problem might be?
We are a dealer and have seen that happen with video card/driver
issues before. Try changing the video drivers in Safe Mode.
Trying a different video card may also help to figure out the cause.
Good luck.

Thanks Kevin,
I've downloaded latest nvidia driver, uninstalled existing driver, rebooted
and installed new nvidia drivers.
Am now getting BSOD if I try to boot into xp. The error codes are
gobbledegook to me but no drivers or services are named.
PC will will still boot to safe mode reliably.
Have run hdd diagnostics and that is resulting ok. Am now running memtest86
and will probably let it run for the night.
I know little/nothing about PCs but am I wrong in thinking that this
might be a software rather than hardware problem?
It will boot reliably to safe mode but not to *full* OS.
Nick.
Scratching balding head and shuffling up the wooden hill.
Start with the basics. Download memtest86+ from memtest.org .
It will format a blank floppy for you (or there is also a
CDROM version, for those who don't own a floppy). You boot the
computer from the floppy diskette (make the floppy first in
the BIOS boot order), and a testing screen at 640x480 resolution
will appear. Let the program test the memory for two full passes,
error free, before booting into Windows. If you have bad memory,
a side effect of bad memory, can be the corruption of the Windows
registry.
The test program runs in a loop, and when you stop it, the computer
reboots. If you are happy with your test results (0 errors listed
in the screen), then when the BIOS screen appears on the reboot,
you can set the boot order back the way you had it if you want.
If errors are shown consistently at the same memory locations, it
could be bad memory. If any errors show, then it could be that
some adjustments have to be made to memory voltage, memory
timings, or to the memory clock setting.
If Safe Mode is using a different or smaller portion of memory,
that could be a reason why Safe Mode is better. If the memory tests
clean, then the next thing I'd work on, is video card settings. On
an AGP motherboard, this might amount to increasing the AGP
voltage setting a bit, reducing the AGP multiplier (from 8X to 4X,
for example).
Video cards can also fail, and sometimes the GPU or the memory
cannot run at the stock speed. There are usually utilities
around of one sort or another, that allow changing the core
clock and memory clock on the video card. You can turn those
down a bit, and see if the symptoms of the problem change
or not.
