About half the time during my startups I get one of the
following messages:

1. Windows protection error. You need to restart your
computer.

System halted.

OR

2. An error has occurred. To continue:
Press Enter to return to Windows, or
Press CTRL+ALT+DEL to restart your computer. If you do
this, you will lose any unsaved information in all open
applications.

Error: 06:0045:00005865

Press any key to continue

I then need to restart the computer manually then it
starts fine and performs fine. This has been going on
sporadically for some time. Any ideas?

Thanks!
