Monitor goes into sleep mode

[clueless1]

I just changed out the K7SEM Micro ATX motherboard in my computer with an identical board (used one). My computer is about 5 yrs old, it is a V2 Premier 100/133 mhz, Windows XP os, with DVD, floppy drive, cd/rw.
Just a basic computer.
My problem is, when I power up, the monitor immediately goes into sleep mode before anything appears on the screen, so I am not able to run any setups etc. I am using the same HD as I was before, so everything should still be on it.
Any suggestions as to how to fix the problem would be appreciated.

Thanks, clueless1

Edit: Please post in the proper forum, from now on.

this bios settings in the mobo you are using have probably been changed, or there isnt enough power..or the mobo is defective...where did you buy it from.

I had to reset CMOS

Thanks 0009 for your suggestion. I finally figured out that I had to clear the CMOS settings by removing a jumper and then replacing it. My computer is now up and running.
