I've been having a problem with a new P4 pc that I just recently aquired. 95% of the time it gets rebooted I get a blue screen saying Umountable_boot_volume, when I eventually get into windows everything seems very slow. I have done a /chkdsk /r, fixboot. I have also switched my ide cables for my hds and the same thing occurs. I'm thinking about updating my bios but I'm wondering if anyone has gone through this before. I'm using windows XP pro, I have done all critical updates, using an Intel board and P4 chip. any help would be very appreciated thx.
