I have a problem with my office pc. It has a pentium 4 3.00 ghz processor, 512 mb ram, 80 gig seagate barracuda hard drive running Windows XP pro ver. 2002 with sp2.
When I leave the office at night I log out and leave the computer on the windows log in screen. Last week when I came back in the morning the screen was black and it had the error message "Reboot and select proper boot device or insert the boot media in selected boot device." When I tried to warm boot it with ctrl-alt-delete, the computer rebooted and went right back to that error message. When I press the reset button on the case, the computer reboots and loads windows fine. This has happened every morning this past week. It always starts up fine after using the reset button, and seems to operate normally all day. I only got that error message one time during the day, when I returned to the computer after a 45 minute meeting.
I have tried playing with the power settings, standby and hibernate are both set to never. I checked the bios settings, and the hard drive is set to boot first, then the cdrom and floppy. I reseated the sata cable and the power cable on the motherboard and hard drive. I downloaded seatools to run diagnostics on the hard drive, and it passed all of the tests. I don't know what to try next. Any help is greatly appreciated!
