I've killed my motherboard ?

**Castle** · 21-11-2008

Hello,

I admit being part of the apprentice sorcerer and I just may be making a beginner's mistake. A few days ago one of my strip dropped RAM. After they finally understood what was happening (Windows is zero indicate the real problems), I decided to make a quick upgrade. I change my old strips of PC2100 against PC3200. I reinstalled Windows XP and I realized that I had forgotten to put the drivers in my motherboard. So I put the CD came with the motherboard and route for installation. ..

I wish to state that my card is supposed to have a bus speed of 800MHz max therefore a 400 I still ok!

Going into the BIOS my system would not detect the actual speed of RAM (266 to replace 400 MHz) So I manually change the speed of RAM and the "timing" I rule "user defined" instead of automatic. A stroke of F10 to save and restart ... but it does more restarts. I have electricity (the disc so the fan running ..) but more small beep and nothing on the screen.

Are there a miracle solution or am I right to replace the motherboard?

Thank you

Are there a miracle solution or am I right to replace the motherboard?

Hi,

Today, a small subject in which I will give info to reset the BIOS.

Reset the BIOS Clear CMOS = = = CMOS CTS Clear ... Several terms refer this operation.

But first, a definition - briefly - BIOS:

The BIOS (Basic Input / Output System - System Input / Output Basic) is a program stored in a memory of the motherboard (memory called CMOS) and determines that a PC can do without accessing a program that would be located on a disc.

Thus, the BIOS can control keyboard, display, disk drives, communications (serial port, for example), and has many other functions.

Where the PC unbootable (due to mishandling, for example) and you no longer have access to the BIOS, the "Clear CMOS" may be the solution. This is to reset the BIOS and to reassign its original values (Factory Settings).

The rider to reset this is in most cases, next to the battery of the motherboard. However, a small check on the instructions of your motherboard to ensure it will not be redundant.

Here's how:

1. Turn off the PC,

2. Unplug the power cord,

3. Remove the side panel of the PC, to gain access to components,

4. Reaching the case of the PC to bring the electrical potential of the body with that of the computer,

5. On the motherboard, find the battery plate, and just next door, which allows the rider to reset the BIOS .

6. The rider will be moved from its original position (positions 1-2) in position 2-3:

7. When the rider has been moved, wait a few moments, then return it to its original position (positions 1-2). Up the PC, reconnect and restart.

This manipulation applies in most cases, however, there is sometimes some subtleties. Do not hesitate, in this case, refer to the manual for your motherboard, which will give the exact procedure.
