Question : BIOS is not ACPI Compliant...but It's not my motherboard??

Ok, I got the "The Bios in this system is not fully ACPI compliant"

So naturally, I updated the BIOS for my motherboard to the latest and flashed it with ASUS's lates Bios for my A7M266 Motherboard thinking that was all I needed to do.  Wrong, still get the same error after putting in the Win XP Pro disk and booting up with it to start installation.

Next, I figured the motherboard was either bad or not compatible with XP which with ASUS wouldn't make sense, but I went and bought the A7N8X new motherboard.  Now this is a new motherboard for 2003, so this definitely should not have a problem.  I still got the same error!  at this point I am frustrated and am somehow thinking about the RAM as a possible problem.

Next I thought that maybe the Video card had an old BIOS.  I tried another one, same problem
Next, I tried to take out the Sound card.....didn't help

Finally, I tried a whole new Hard drive since I was getting errors when also trying to run setup for Win2000 since I thought I'd see if Win2K would install.  It had problems installing Kernal files or something.  Also, I tried to boot up with Partition Magic boot disks to format and partition my hard drive.  I never had problems with that either but it also had problems writing to the hard drive.

So I replaced the Hard drive with a new Maxtor.  Didn't help, still get that error.

Now I have narrowed it down to either I have an incompatible RAM Dimm (DDR), or my Panosonic DVD ROM which I doubt it is neither because if it was my RAM, I would have a whole lot of problems.

Also, I noticed that the user was using it a month ago and the system would shut off on him randomly, the whole PC would Just shut off as if you unplugged the cord.....plus the user was getting some video specs when booting up, so I thought is was the video card but this is not the case.

What else can I try other than the RAM?  Can Anyone tell me what the heck it could be other than the items above?

>>>if it was my RAM, I would have a whole lot of problems.

Not necassarily. RAM can have specific problems that only show up at certain times. If you want time to test the RAM then...

Test the RAM

NOTE if this doesn't find anything wrong with the RAM this DOESN'T mean the RAM is good you would need to swap out the RAM with known good modules for testing. However if it does find something wrong then chances are the RAM is bad.
