Hi

went to turn on my pc yesterday , and it rebooted during the memtest.

Sometime sit gets as far as identifying the drives then powers down
and occassionally will load windows and then power down after a few
minutes

I have tried stripping out all cards and replacing with good memory
and removing all drives but problem still occurs.

I have reseated the processor and blown out all the dust from all heat
sinks , I dont think its a heat issue as both the power supply and
processor fan are spinning.

The board is a ASUS P5VDC with 1 gig (2x512) ram and a P4 3000
processor

Any clues

Psu or mainboard. Take your pick.

I'm having a similar problem, not as serious as yours and only happens
ocasionally. I though it was overheating first. I added 2 fans,
improved the air circulation and changed the thermal compound. Now CPU
temp is around 49C, ~+8 under heavy load. I even downloaded a patch
from Microsoft to throttle cpu usage more efficiently under XP SP2,
the improvement is barely noticeable. You didn't mention the PSU,
other than the fan spinning. If you are using good quality RAM as you
mention, the only thing I can think of is that you may have a flaky
PSU or a motherboard problem like someone correctly pointed out. In my
case is the PSU. This is the first pc i built so I don't have further
experience. Perhaps someone can elaborate further on this issue.
