Every morning I need to reset 5-10 times to get display. When display is ok, I get "cpu over voltage error' message everytime booting up. Already updated the latest bios version. I never ever do overclocking or any settings. Have tried cleaning and reintalling the mbo and cpu. Cpu is intel p4 3ghz. Please help. Thank you.

Hi Ulrich, thanks for replying. I let the pc on from this morning till now. 9.30am this morning: CPU Temperature [0C/32F] MB Temperature [9C/48F] CPU Fan Speed [1298RPM] CPU Q-Fan Control [Enabled] CPU Fan Profile [Optimal] Chassis Fan Speed [N/A] Power Fan Speed [3096RPM] VCORE Voltage [0.000V] red color 3.3V Voltage [0.928V] red color 5V Voltage [6.323V] red color 12V Voltage [0.000V] red color Now 11.45pm, all same except: CPU Fan Speed [1318RPM] Power Fan Speed [3082RPM] After upgrading the bios ver few days ago, cpu fan less noisy. Problems still same, like what I described in post 1. Once on and running, pc works fine. Reset/restart pc also ok except the error message remains.

Hi s..

Sort of sounds like the power supply has a problem getting voltages into specification..  if it can't do that, the system won't start.  Apparently after multiple power ons, it works but the voltages reported in the BIOS are still out of whack.  It may be an issue with the new BIOS... so if you didn't do a CLRTC, try that.. and swapping in a different power supply might be another consideration.
