Having problems with your Intel Pentium 3 , 450 MHz Pentium III (SL364) Boxed Processor ?

I accidentally changed my CPU clok frequency from 100 to 250 and now my computer won't boot?

\015 Ok, I tried to 'overclock' my Intel Pentium III Processor like in PC Maga while back and now my computer will not boot. I changed the clock frequency instead of the clock speed. When I boot my computer it powers on and the CD drive hums for 2-3 secs and the computer dies down like it is in stand-by.I have tried booting my Win XP cd to repair Windows XP to try that but my CD drive will not boot anything either. I also tried Fix it Utilities 6 boot cd but it wont boot either. Can someone please help me???\015

Ok I realize this is old and you may have given up by now or gotten it figured out, but I'm gonna try to help even with that being said, first of all I just recently had the same problem, this is a sure fire way to fix your issue,
\015\012step one, open up your computer so that you have access to the motherboard,
\015\012step two, find the system battery.
\015\012step three, near the battery there should be a jumper, this will be a little plastic piece with metal connectors inside it, it should be slid onto two pins out of three available, move it over one space meaning if its on the left and middle move it to the right pin and middle pin, the three pin pole should say cmos right by it, or clear cmos.
\015\012step four remove system battery, no need to worry this is just the memory for the cmos chip and it will revert it back to when the board was new, you can change the settings in your bios program back to what they were when it last worked,
\015\012step five, making sure that your power cord is not hooked up to the computer in the back, (no power to computer) press and release your power button a few times, (this will drain the capacitors stored power)
\015\012step six, walk away for about 20 minutes, just to make sure that clearing of cmos was a success,
\015\012step seven, replace cmos battery.
\015\012step eight, move jumper back to original possition.
\015\012step nine apply power to the computer and boot up should be operatioinal again, you can then go back into your bios setting and change as wanted, however I would only overclock a little at a time as boards will only handle so much overclocking before they will freeze up, i would not go more than 200 mine froze at 200 so you may not even want to go there, Hope this helps.......
Turn off you computer, set the bios setting by removing cmos battery and clear the cmos jumper.Then back it on, power your pc now.

I have been having some boot problems into windows with my p4s800 mx motherboard. I have purchased it with a 3,0 ghz cpu and put it together yesterday, after which I tried to boot it. It works on lets say 6/9 times, but the 4/9 times it wont boot into windows. After the boot failure, the system automatically gets into bios and tells me that the ''system hung'' and that I should adjust the frequency of my CPU. I am currently not overclocking the system and have the same problem when I try the 1,5

The BIOS utility probably has a setting for the BIOS to automatically detect and maintain your CPU's clock speed. Make sure that is ON or ENABLED. Another probable reason for the failure may be your RAM settings. Again, use the automatic detection ... PC Desktops
