I have windows 2000 installed on my notebook and whenever I boot up for the 1st time for the day (or after I let me notebook powerdown for like 1 hour), it hangs right before windows 2000 boots up. I'm forced to power down and restart. This usually takes about 6 times before it works. Anyone have any idea about what may be causing this? I've already re-formated and loaded the os back on. I also set the BIOS back to its inital settings.

Thanks
