I have a ASUS P4PE mobo with a Intel P4 CPU 2.4GB and when I boot up the BIOS tell me to enter BIOS and check Power Monitor.. once there I find that the +3.3 voltage is in RED and reading 2.99 and sometimes abit lower 2.97 and I have to tell BIOS todisable the reading in order to be able to boot into Win 98se..Once into windows I check PC Probe to see what is going on..the temperature is ok the Voltage Monitor is resding +12 @ 12.288 and the +5 @ 5.107 and the +3.3 @ 2.98 and 2.976 up and down.. the Vcore is at 1.632 the Threshold defaults are set @ 10%.. I have to change the +3.3 Threshold to the Max of 15% to keep PC Probe from popping up all the time while I am on my comp. In the BIOS the CPU is set @ 2400 MHz 18 x 133 which is right and fine,but that +3.3 bothers me… I got a new power cord– didn’t fix the thing… Greased and reset the heatsink and CPU… no luck..Am thinking that it may be the power supply 350W …Any help wolud be great…Thanks….
