If you’ve changed your CPU or overclocked your system, the system may fail to boot up,
even with a Clear CMOS jumper physically resetted. The reason is that nVIDIA’s new
nForce2 chipset introduces a way to reset a Clear CMOS jumper without removing a
chassis. Please follow the steps listed below:
1. Turn off your computer and unplug the power cable. Reconnect it after 30 seconds;
2. Press <Insert > and then press your computer’s start button. Continue holding <Insert>
until the system begins the POST (Power-On Self Test);
3. Immediately press <Del> to enter the BIOS;
4. Select ‘Load Optimized Defaults’ to return your system to a bootable condition; then
select ‘SAVE to CMOS and EXIT’;
5. Reboot your system.
Your system, however, may also not boot up after you’ve resetted the CPU FSB. The remedy
is to highlight “SAVE to CMOS and EXIT” in the BIOS and then restart your computer.
There will be on screen a message warning you not to reset or turn off your computer, a
message described as:
Warning! New setting is updating now
Do not Reset or Shutdown the system
The system works after updating the BIOS.
