1st question: I have an older Dell 8100 that has worked well as a second pc in my garage. A few years ago I upgraded the 423 p4 1.6 cpu with a 478 p4 2.8 via power leap and their adapter. All has been well. Has 1 G rdram, Win XP home. I believe I cooked the mother board a couple of weeks ago by having it contained in a unvented cabinet. I found, ordered and installed the same mother board. Installation went well. All was identical. Upon boot into the Bios, I see it only recognizes the cpu as a 1.6. I reset the Bios and it still only recognized it as a 1.6 p4. Could this be because of an out dated bios?

2nd question: Upon normal boot up the windows logo would come up but all would freeze and go black screen. Is it possible I will have to reformat and reload the OS because of the duplicate mother board replacement?
Thanks for your help guys.

Since you were the one to install the power leap adapter originally did it require a certain bios version ["or above"] to work ?

If the replacement motherboard is identical to the original Windows should start with no problem.

Try starting in Safe mode.
If it will start go to the device manager & uninstall the video, sound, & LAN [network adapter]
See if it will start normally .
You may have to download the proper drivers & install them.

Mine was doing that til I replaced the MB battery. Kept going into the bios and showed it was still operating at a slower speed and had to upgrade the clock too. New battery and walla!

I'm assuming that you just put the old hard drive back in
Besides the BIOS, there might be a chip or two that's not the exact same thing

Hi guys, thanks for the help
When I purchaced the board the MX-025REH was what I was suppose to get.
the serial # on the old board is MX-025REH-12405-13E-1500 REV 02.
the serial # on the replacement I was sent is MX-09D307-12405-14I-0559 REV 01
I'm assuming the board was bad because there was no power going to the board at all. Checked that with a psu swap. I will try the bios update but assuming that I can get windows running and to Dells support site. Booting into safe mode froze early where I think all the drivers are loading after I choose boot into safe mode. I also tried to put the old 1.5 cpu in to see if it would boot and that did not work. I'm not opposed to reload of the OS. Just looking to save time and aggrevation.

The replacement motherboard isn't exactly the same as the original.
The replacement is an older version of the motherboard.

" old board is MX-025REH-12405-13E-1500 REV 02."

" replacement is MX-09D307-12405-14I-0559 REV 01 "

I have never used a power leap socket 423 to 478 adapter but there is the possibility that the older revision motherboard simply won't support it properly.

Just for the heck of it, I powered the other supposed bad MB and it had life. Put it all back together as it was before I took it apart and all works again. Puzzles me why but $19.00 later and a whole bunch of time, and advice from you guys, I'm a little more knowlegable. Thanks for the help guys. LOU
