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.
