I suspect that the case front on/off switch is not connected to the proper pins on the motherboard. If the motherboard's power activation pins are shorted, then it starts every time on applying AC.

2600+ with ASUS MB A7V266-E/AA


Here is the CPU Support list from Asus Support, for the Asus A7V266-E,
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=A7V266-E/AA&product=1&os=17

Scroll down the list. 34th one down, that is listed.

1.Did you get the Athlon XP 2600+ that has a 266MegaHertz, (MHz), Front Side Bus? (FSB)
The AXDA2600DKV3C?

There is an Athlon XP 2600+ that has a 266MHz FSB, and one that has an FSB of 333MHz. <-This one Won't work.
Model number ->AXDA2600DKV3D will Not work.
Both are Thoroughbred A/B Core models.

The AXDA2600DKV3C has a 12.5x multiplier.
Your 1900+ has a 12x multiplier. (AXDA1900DUT3C) They both have an FSB of 133MHz. (Shown as 266MHz because AMD processors are 'Double-Pumped')

A.The AXDC2600DKV3C will not work. It has a 16x multiplier. (Thorton Core)
B.The AXDC2600DKV3D will not work. It has a 333MHz FSB. (Thorton Core)
C.The AXDA2600DKV4C will not work. It has a 15x mulitplier. (Barton Core)
D.The AXDA2600DKV4D will not work. It has a 333MHz FSB. (Barton Core)
E.The AXDA2600DKV4E will not work. It has a 400MHz FSB. (Barton Core)

2.Are the jumper blocks -> CPU RATIO, and SYSCLK, still set in the Jumper Free Mode?

By the factory default settings these jumper blocks, (DIP switches), should already be set to Jumper Free Mode.
The white DIP switches should be in the OFF position. (The white switches will be DOWN, towards the numbers on the jumper block CPU RATIO. They will be UP, away from the numbers, on the jumper block SYSCLK))

The CPU RATIO jumper block is right above the processor. It is a blue rectangular block.
The SYSCLK jumper block is down the motherboard, right below the AGP graphics card expansion slot. (And above the first PCI expansion slot)

If those two jumper blocks are not set to Jumper Free Mode, set the DIP switches in the jumper blocks to this setting.

Now go into BIOS Setup. In the main menu use the Right Side Arrow key on your keyboard, and highlight Advanced.
If -> CPU Speed is set to Auto, you won't have access to set your CPU parameters. If it is set to Manual, you will see them. If it's set to Manual, write down the headings, (CPU:System Frequency Multiple, System/PCI Frequency (MHz), and so on) Write down the numbers to the right of these headings. If something goes wrong, you can go back into BIOS Setup, and change them back.

1.CPU:System Frequency Multiple should be
12.5X
2.System/PCI Frequency (MHz) should be
133/33
3.System/DRAM Frequency Ratio should be
(Auto)
4.CPU Vcore should be (1.750)
5.CPU Level 1 cache, and Level 2 cache should be (Enabled)
6.CPU Level 2 cache ECC Check should be (Disabled)
7.BIOS Update should be (Enabled)
8.PS/2 Mouse Function Control (Auto)
9.USB Legacy Support (Auto)
10.OS/2 Onboard Memory >64M (Disabled)

Leave the rest alone.

The AXDA2600DKV3C uses 1.65 volts, has a 12.5 clock multiplier, and a 266MHz FSB. (You will see 133MHz, and set all your settings to 133MHz. AMD processors are 'Double-Pumped'. Intel processors are 'Quad-Pumped')

My Mb does not give any sign, . What can I do ? Everything is desconnected except power on the Mb and the Mb switch. I switch the machine on and the only thing works is the CPU fan No any beep


Sometimes you have to have the motherboard , power , cpu , memory and 1 drive connected (IE the basic components) to get the system running

Also check the jumper settings where the board connects to the power switch on the case

CHANGING CPU'S TYPES AND SPEEDS


On these old motherboard there is usually one switch that is used to change the CPU type - from Slot to Socket, in this case. But there are usually a different set of jumpers that control the CPU speed. And usually another set to control the bus speed, assuming it supports more than one. In this case it might support 100 or 133, depending on the CPU.

In some cases, you can set the jumpers to "AUTO", which automatically selects the bus and CPU speed. This was only available on the higher end, newer and more expensive boards.
