Strange one here.
Plugged in system from customer. Booted fine but system clock wrong. Reset clock, rebooted and all was fine. Then powered down sysem, removed power plug and let rest. Plugged power back in, and the same thing occurred. Powered down, and replaced CMOS battery (clock was also wrong in BIOS prior). Booted and reset clock in CMOS. Booted fine. Powered down, then tried to reboot. Received error beeps, turned off system, tried rebooting. Same beeps. Turned off, pulled power cord, let rest for 10 minutes. Powered on and it booted (with wrong time in BIOS). This is driving me nuts. Could it be the motherboard?
Customer was complaining that her video was not working (her monitor would not show booting). I went to her home with another monitor and replaced monitor while PC was still running... and NOTHING. And I know the monitor was good! Brought it back to my lab (the PC), booted and it worked with the monitor.. but then noticed the system clock.
High points since this is driving me nuts!
