Re: Vista freezes solid on AMD dual core, single core ok

Nothing in the event logs, except a note that the shutdown was unexpected.
Re. memory: I originally had 2GB matched DDR2 RAM, where I already had the
problem. Then added another GB matched to 3GB, and also tried with only the
new 1GB installed. Same difference.
On virtual, it's normally on "system decides", but I also tried to limit to
512-1024MB. Same thing.

BTW, forgot to mention earlier that temperature is nice and low, enough
ventilation and fans going and monitored via Everest. Lock-ups are not in any
way linked to temperature increases, high HD activity, or high CPU load.

Only remedy is 1 cpu only, or it seems to run in safe mode, but this is hard
to test, as the only sure way I had to crash is using Word, all other freezes
feel random, and Word wants a new activation if the system is in safe
mode.... Not going to open another can of worms there.

Anyway, 1 cpu seems to work, safe mode seems to work, but even in a
diagnostic startup it crashes. Makes me believe it would be some device
driver which loads in diagnostic mode but not in safe mode. What could that
be?

Since I changed the graphics adapter to a totally different one, and
disabled most hardware to test along the way, it must be deep in the Vista
system. Any ideas????

Appreciate your help!
