Biostar M7VIG 400 Problems

Hi all...

Recently purchased a new mobo & case/power supply after a power surge took out my Emachine.

Replaced with a Biostar M7VIG 400 & In-win MicroATX case w/ 350 watt power supply.

Going into the machine are 256 megs of RAM (factory ram from an emachine D2346).
AMD Athlon XP 2800+
Hard drives, DVD Burner, etc.

Anyway, according to AMD spec this processor is supposed to be set to a 166mhz FSB. There are jumpers on the mobo to set to either a 100, 133, or 166 setting. From the factory it was set at 100 and it booted up fine. But when changed to 166, I get nothing. Power spins up, but no POST or BIOS screen.

Is there something I'm missing here or am I going to have to deal with a system dumbed down to 100mhz FSB??

Thanks in advance...

 

Here are a few steps you can take to troubleshoot and hopefully resolve the problem:

1. Check RAM Compatibility:
   
   • Make sure your RAM is compatible with the 166 MHz FSB setting. RAM rated for 100 MHz or 133 MHz might not perform well or be recognized correctly at 166 MHz.
2. Clear CMOS:
   
   • Try resetting the CMOS to restore the motherboard to its default settings. This can sometimes resolve issues related to BIOS settings. To do this, locate the CMOS jumper on the motherboard and follow the manual’s instructions for clearing it, or remove the CMOS battery for a few minutes.
3. Verify Processor Compatibility:
   
   • Ensure that the AMD Athlon XP 2800+ is supported by your motherboard and that it is properly seated in the socket. Sometimes, an improper installation or a CPU that isn't fully compatible with the motherboard can cause boot issues.
4. Update BIOS:
   
   • Check if there is a BIOS update available for your motherboard. Sometimes, updating the BIOS can resolve compatibility issues with newer hardware settings.
5. Check for Additional Jumper Settings:
   
   • Some motherboards require additional settings or jumpers to be configured correctly when changing the FSB speed. Refer to the motherboard manual for any specific instructions regarding FSB settings.
6. Test with Minimal Configuration:
   
   • Try booting the system with only the essential components (CPU, one stick of RAM) to see if it will POST. This can help isolate any potential issues with other hardware components.

If after these steps the system still doesn’t boot with a 166 MHz FSB, it might be necessary to run it at the 133 MHz setting or consult with Biostar support for further assistance.
