Soyo mobo still won't run at 133

Hardware:
Soyo k133 ultra platinum mobo
1 stick Crucial pc2100 256 meg ram
All-in-Wonder 7500 video card
Maxtor 40 gig HD

Problem:

BIOS set at 133mhz:
System won't load OS (98se or 2k) freezes or errors out.
If I do get it loaded the all applications are unstable yielding bluescreen errors, freezes, GPF errors and or spntaneous reboots.

BIOS set at 100 mhz:
All is fine.

Have replaced the stick of ram with same results for both settings.

What do you think the problem could be!!!! HELP!!

thanks!

Thanks for the reply. Since I have ruled out just about anything else, guess it may be time to mail it in to AMD for a new one!!

 

you're welcome, and good luck
