Hardware Monitor Setup Freeze (K7T266Pro2) [SOLVED]

Question

1.Product Type: K7T 266 Pro2 (6380 v2)
2.BIOS version: AMI V3.70
3.External VGA Type: ATI Radeon VE 7000 AGP 128Mo
4.CPU Type: Athlon XP 1600+
5.Memory Type: 2*256 Mo DDR PC2100 PQI
6.Power Supply Type: Heden PSXA870 380W with -5V output
7.Operating System: Win XP Pro Sp2
8.Problem Description:
When accessing to hardware monitor setup page in BIOS, I get a freeze that I can olny escape by Ctrl Alt Suppr.
I have made an update of Bios to V3.70 because a new module of memory I have bought make problems. This update do not change anything, so I remove this new module and don't use anymore.
But by updating, my CPU clock down to 1050 Mhz instead of 1333Mhz, due to FSB set to 100Mhz.
And impossible to access the page to set the parameter at 133Mhz due to a freeze.
How to solve the problem and get back the right configuration I had before ?
I have read that the problem may come from the power supplies that don't have -5V. I don't know what produce my PS, but how to prevent BIOS to check this -5V ?
EDIT : I have check my PS and it produce -5V.
Many thanks for your hlep.
Regards.

Merry Chrismas everydody.
Back with happy news :
- I have flash with v3.7 : flash OK
- Still getting the problem : hardware monitor page setup freeze, and unable to set FSB to 133Mhz and get the right CPU clock.
So, my solution :
- Looking for editing the AMI Bios file.
- I have load v3.70 Bios file in editor, and only change one parameter : I have set not active the -5V check in hardware monitor module.
- Save my new bios file (called it v3.71)
- Then, flash with that edited bios file
- And manage to access the Hardware Monitor Setup page to set the FSB at 133Mhe. No more freeze.
I don't know how to call this type of solution, but it works well.
