Vista hangs occasionally and after reset disk seems to not to be bootable

[pawel]

Hi,
I've got a quite a problem here I've been using vista buissness for over
a month now, and recently vista started to
occasionally freeze in the middle of games, watching movies, listening to
music and so on. Only thing I can do with it is to push the reset button to
reset the computer. What is different from other situations that other
people reported here is that ... well after the reset the disk seems to be
not able to find the boot sector valid. Vista simply does not boot.
The tricky thing is that when I enter the BIOS and try to auto find the
parameters of the disk, then reboot the computer all is ... fine vista boots
without any trouble... presto.
Does anyone now what can be the problem (mainly these occasional hangups,
the disk issue can be very well hw issue). My specs (rough) are:
Vista buissness 32bit
2GB ram dualchannel mode (2x1gb)
hdd wdc caviar 250gb
board evga nforce650i ultra
graph evga 8600gt
SB x-fi gamer

if anyone has similiar setup and is having similiar problems please write
me, it would help me to narrow the problem to hw issue

thanks for reading this
pawel

I forgot to mention that all drivers as well as the updates are recent and I
have the service pack 1 rc (I instaled just after the installation of vista
over a month ago)

A 'chkdsk' may help

Right-click c: in 'Computer' > Properties > Tools > Check Now (under 'Error
checking') > ok
Schedule for the reboot.
