CPU Speed Problem!!!

[baoluanle]

Thanks in advance for all of your responses!
My problem is that, someone (I don't know who) messed with my computer cmos ram setting and when I booted it, it ask me to "reselect the CPU speed". So I went in the set up and changed the CPU speed and now my pc wouldn't even start! Nothing shows up on the screen when I turn the power on! Please let me know what the problem is and how to correct it! Once again thank you very much for any hint, even if it doesn't help!!!!!!!!

Im not a expert or anything but tried clearing your cmos from the motherboard. It should show you where to clear the cmos in the motherboard manual. Dont know if it will help. After that youll have to go in the bios and set every thing back up again.

If Clearing the CMOs does not work as diurnal posted than post more info on your system this will help us in helping you to correct the problem.

The reason your computer is not starting is that you didnt select the correct CPU speed for the specific chip in your computer and the bios is automatically trying to start the computer at a MUCH higher or lower clock setting than the cpu chip can tolerate!!! Try going into the bios again and make SURE you know what cpu you actually have (the mhz rating as well as which bus speed the cpu runs best at). There are some mobo's that offer several "ways" to achieve a specific mhz rating (ie you can get to 300 mhz with a 66 bus speed and a 4.5 mulitplier or 100 bus speed and a 3 multiplier, but one of them might not work with YOUR cpu). If it wont even start up.....clear the cmos by moving the jumper to clear setting and then start up /shut down and move it back to "Normal" mode...that will bring you back to square one and you can start over. If you cant find the "Clear cmos" jumper.......pull the cmos battery for 15 min and put it back in.....that also will bring you back to starting point. Good luck!!

Also some BIOS setups allow for an auto-detect of the CPU you cantry that if you've got it.

Thanks again for all of your inputs. The problem remains is that when i turn the computer on nothing shows up on the screen; therefore i can't even go in the set-up. I thought about pulling the battery out of the cmos ram but didn't do it because i was afraid of losing the bios of the cmos ram. Is there any way to put the set-up back to its original settings? I guess I would need to be able to get in the set-up first!
Again thanks for all of your responses!!!!!

Yeah, usually there is an option "Reset Default" that will put the default values (they tend to be hard coded in the BIOS and changes get saved in CMOS). Also if you have the manual for the motherboard somtimes they have basic settings that can be manually input on first start.

Once Again, Many Thanks to All of Your Responses!!!
I finally had the courage to pull the battery out of the cmos ram and started all over again! Now my system is back and working! Thank You's!!!
