guys, mangayo unta ko sa inyong mga opinion kung unsa sa tanaw ninyu ang problema.
my toshiba portege m900 shuts down the moment mag load pa lang ang windows AND this only happens during the first boot up for the day.
details:
in the morning, i turn it on, first time it was turned on for the day, then the moment na mag load and windows (vista - loading bar / windows 7 - kanang mo sidlak na ang windows logo) then it will shutdown completely.
when i turn it again, mo sud na siya sa windows (of course i get the error na windows was not shutdown properly...... so i just select "start normally" then ok na), then i can use my laptop normally.
i doubt it's a software issue kay the same thing happened when on windows 7 and when on the default OS vista (i ran factory recovery to see if it helps but same problem happened).
i also ran memtest and ran diagnostics on the HDD using seatools, ok man wah may errors...
unsa kaha ang problema ani sah? i think it's with a certain hardware device somewhere/somehow na when windows loads the driver for that particular device, it crashes the whole system...
by the way, mo sud siya drtso sa windows kung safe mode, dili siya mamatay even if it's first start up for the day...
the big question now is which hardware is most likely at fault here...

appreciate your inputs guys...
thanks!!
