Boot problems Asus A7v133c

By pgm554 ·
AMD XP2100+ installed .Booted once , set the CMOS, rebooted . Now it won't POST. It has no clear CMOS jumper . I am thinking of using hard dip switches on the MOBO to see if that fixes the problem. Anybody see this one before?
Everthing is new (mobo and cpu).

Boot problems Asus A7v133c

I have had similar problems with the older A7V's.

The fix has been to set the CPU FSB and multiplier manually in BIOS settings.

To get the motherboard to boot, remove the CMOS battery, and unplug the power supply for at least 1/2 hour.

Onceit boots, enter BIOS settings, and replace the battery.

Set the FSB and multiplier as needed for your CPU and memory.

Remember, the XP series Athlons are 'performance' rated.
The actual CPU clock speed is a bit lower.

Check AMDs current data sheet for your CPUs actual FSB and clock speed.

While the FAQs at this site:

Focus on ABit motherboards, all of the VIA information caries over to the Asus VIA chip-set boards.

Hello,

before removing the CMOS-Batterie try the following to reset the BIOS to the default-values

Press the Insert-Key (not the numeric keyboard)
Turn On the PC

On most MoBos this will reset the BIOS (without the passwords)

This is easy.
To return to the beginning, and get rid of the BIOS error, Unplug PC from wall, and remove batteryReplace battery and plug PC back in.
You now can try again.
Be more conservative on the BIOS settings.
Many people set all the BIOS settings to the fastest possible on the initial boot, and then this problem occurs.
Remember the old rule of troubleshooting PCs.
Change only one setting at a time.
Yes its slow, and I ignore it sometimes, but there is some truth in it.

My roomate and I got the same issue once where our pc wouldnt boot after replacing the AMD processor. After trying everything we called our guru friend to assist. He came over removed the processor and pushed down a resistor that was located in the middle of the processor housing. It booted up immediately while he was laughing at us. In short the processor wasnt making a complete connection, it goes to show you that check even the stupid stuff.

I 've tried the suggestions . No go.

I could be stuck in a loop. This MOBO will support the 2100+ with a flash update , but I couldn't see the BIOS rev since it only booted once correctly.(needs 100

I might need to go with a lower level chip (older Duron or such) in order for it to POST again, and then flash it.
It's a 1.05 rev and should handle the 2100+ chip. The trouble is , I don't have an older CPU handy.

I am going to give Asus a call(although have have heard not such good things about their tech support).
Otherwise, it's DOA time.

Thanks for the suggestions.
