Hello, ok my problem is my PC that is running Windows XP service pack2 will not boot properly. I was in the startup menu (the one where when your PC is booting you press DEL) and i changed some CPU settings (i changed the speed of it from like 850 to like 1300 or sumthing like that). After i pressed F10 to save settings my PC just crashed and now it wont boot and the screen wont even turn on :S. Please HELP me!!!....Power down the machine.
Remove the power cord from the outlet it's plugged into.
Press the On switch on the front of the machine a few times.
Now you need to remove a side panel or the case cover to remove the CMOS battery. located on the motherboard.




Be careful removing it as rge spring clip that holds it in is easy to break. Wait 10 minutes; replace the battery hook uo the power and boot up.

Refrain from foolin around in the BIOS.....lol, thnx 4 da help i was just curious, and i geuss thats probly not the best thing 4 my computer
IF only it was that easy to speed up your computer. lol......yh......im still havin trouble tryina get this darn battery out, im not very good at these small things:SA toothpick is useful...it should break before the spring does.

You definitely DON"T want to break that spring unless you are in the market for a new MBoard or have superior soldering skills...hey, so if ive broken it it will stuff up my pc, cause it did work and fixed my pc but then after about a day i had the same problem again, do you THINK it could be because ive broken the spring?Did you replace the battery ? ?
If so it wouldn't go dead that fast...
Have you been messing around with CPU settings again ? ?
If not the machine has other issues.
Please post what it's doing now...yes i did replace the battery and nothing happend, no i havent been messing around with the cpu settings, and when i push the power button to turn it on nothing comes up on the screen, it just stays black and nothing comes up(i have it all pluggd in right and i have tried other monitors on it), the motherboard doesnt BEEP like usual when it loads up either. The computer is an OLD one, i think i got it like 8 years ago or something like that and we have replaced the mother board twice from failures and added more ram. Im not to sure on the hardware specs for it because i was like only 8 when we bought it and im not sure on how to find them out.
YAY.......i fixed it, i just went around the insides of if for a bit adjusting cables and giving it a clean and now the screen loaded up. I think i might just reset the bios settings just to be safe thankyou all for your help and sorry about the double post :S
