Good morning everyone

40 gig hdd 256 mb ddr pc2100 ram dvd player burner geforce mx400 64mggraphics card 350 watt power supply
the problem is that sometimes when i boot up it goes into the bios setup stating that the cpu is new or replaced but it is not could the motherboard be to sensative to a cpu frequency change and if so is there a way to rectify it apparently the bios chip is upto date
thank you

First, a 350 Watt power supply may be light for your needs. If you add any drives or RAM, I would definitely upgrade the power supply to at least 400 Watts.

While I don't work a lot on P4 systems, I have seen similar problems on Socket A motherboards.

The 'fix' is to manually set the CPU and RAM clock frequencies in BIOS settings.

Go to the advanced section.
Change CPU frequency from Auto to manual.
Set the multiplier to 4.5
Set the Front Side Buss to 533MHz
Set the RAM speed to 266MHz

Save settings, and exit setup.

That should take care of the errors.
