Blank screen after a change in the motherboard's Bios

Question

Hi,
Recently, I have bought a MSI motherboard - 865PE Neo2 FIS2R. The computer works fine after I installed all the components and applications (including Windows XP [included Service Pack 1], Intel Chipset Software Installation Utility and all the drivers), as well as updating the bios to the most recent version.
However, after I changed one of the bios settings as follows:
1. Select Frequency/Voltage Control.
2. Select Performance Mode
3. Select Ultra-Turbo
then I try to quit and choose Exit & Save Changes and press the Enter key on the keyboard. Immediately after, the screen fails to show anything.
The reset button on the computer case also fails to response (the reset button works before this incident). So, I shut down the computer, wait for a while and then power it up again, the monitor still does not show anything. Also, I do not hear any special beep sound. At that time, all the fans in the case (including CPU fan, system fans, power fans and video card fan) are moving. Here are the things that I have also tried:
1) I have tried the monitor and video card separately on another computer and both the monitor and video card work fine.
2) Also, I have tried to clear the CMOS following the procedure mentioned in the manual jumper but the screen still fails to show anything.
Here is my computer's configuration:
Motherboard  :  865PE Neo2 FIS2R (Bios version 1.4)
CPU :           Intel Pentium 4 2.8CGHz (800 FSB)
Memory :        Crucial PC3200 512MB CL3 (two of these)
Graphic card :  128MB Crucial Radeon 9800 Pro
Hard disk :     IBM DTLA-307030
Case :          Thermaltake Xaser III V1000A Black
Power Supply :  TruePower 380 12V AC 380W ATX TRUE380PGB
Therefore, may I know if the problem is solvable and what caused the problem. Also, I have just bought the motherboard for about 2 weeks, should I go back to the retailer to get a replacement?
Thank you anyone whom may help.

Answer 1

The difference in the performance modes above SLOW is the DRAM SPD timings used ...seems yours is unstable at the Ultra-turbo settings (you may be able to use this setting if you increase your DDR voltage slightly though (I use 2.7v for my CORSAIR)) ...only trouble is gaining access to the BIOS to do this
A few things you can try:-
Use only a single stick of memory -go into BIOS and increase the DDR voltage or reduce the performance setting
If that fails and you have another type of DDR available try using a single stick of that instead (DDR 2700 has worked for me in the past) ...this will force your motherboard to boot at the SLOW timings -you can then enter the bios and increase the DDR voltage, save, shutdown and reinstall your memory.
Try booting with the "Insert" key pressed to force the BIOS defaults to be used
Remove the power cord press the "start" button a few times (to discharge any power left in the PSU) remove the CMOS battery and set the jumper to the "CLEAR" position ...have a cup of tea (or coffee) ...reset the jumper, install the battery, insert the power cord, cross your fingers and BOOT?
