Solved Poor PC won't boot due to minor BIOS changes

Specs: Windows XP SP3, Intel Dual Core 2GHz( I think) and 3GB RAM
Hi, my PC has been giving me trouble when it boots for a while, like today. It usually just starts without displaying anything on my screen so I have to re-start it once or twice to get it working properly. Today, like most other times, my PC brought up the option to see and change my setting and I usually ignore it by just skipping to Save&Exit. However today I decided to just go looking around in this stubborn machine of mine and that's where I found the CPU FSB Frequency Adjustment option. I googled it to see what it actually does and I changed it from 200 to 300, thinking it can't make my PC worse... I also changed something els,I think it was the CPU Smart Fan target but I made that 40° and I think 65% or something... I cant be sure because I can't switch on my PC... So any help to get it up and running again would be awesome.

What is the manufacturer and exact model number of your computer. At the very least, you're going to have to get inside and reset the BIOS.

Trying to overclock by 50% was perhaps a little ambitious; that is not a minor change. As already said, you are going to have to reset the BIOS before anything will work. The manual for your motherboard should tell you how to do this.

✔ Best Answer
Check your manual, but it typically is Unplug the computer from the wall/power strip on a desktop system (and remove the main battery on laptop) and temporarily move the CMOS jumper from the storage position to the Clear CMOS position for a few moments and return it to the storage position (If you do not unplug, or do not move it back before plugging it in, you may do damage). If there is no jumper, you would need to remove the CMOS battery (AC power unplugged also), tap the power button a few times, and wait a couple of minutes for residual power to drain out, then reinstall the coin battery (watch the direction), plug it in, and power it up. After you have cleared the CMOS (either method), you will need to go into your BIOS set up and reset defaults, save and exit, then go back in and set time, date, hard drive, boot order, graphics adapter, and possibly other settings, save and exit.

You have to be a little bit crazy to keep you from going insane.
