Hi everyone. I really don't know anything about the workings of a pc so i have no business poking around in it, but I got a free HP Pavilion 8560c to go in my daughter's room. It had no memory, so I bought 2 Kingston KTD-OPGX1N/256 sticks off of ebay. After I installed them, i got a blue screen with an error that said, "BIOS is not ACPI compliant" and it told me to hit F7 when prompted, but I was never prompted. I put the old memory back in and it booted fine. I don't know anything about updating the BIOS, especially on an old pc like this one. It was made to run Windows 98, but it had 2000 professional installed when I got it. What am I supposed to do?
Resetting the BIOS only resets the factory defaults, so yes, it will boot fine. If you're not sure what the BIOS does, have a look at BIOS in wikipedia (just Google 'wikipedia bios').
Also, have a look at the motherboard model (should be written on the motherboard), then go to the manufacturers website and see if there is a bios update (or the bios manufacturer such as American Megatrends will have it) - you may need an update to run the new RAM. Updating the bios is also called 'flashing' (again, see the wikipedia page for explaination). The motherboard/bios manufacturer should also have directions for flashing the bios.
Take note that an older PC like this one is also going to die from something soon - tell your daughter not to keep anything on it that she wants to keep unless well backed up.
I come across this all the time - people want to revive an old machine to 'give to the kids to play with'. They usually don't want old machines - they want the fastest new zippy things that can play cool games on while doing ten things online at the same time. It's usually better to go to an auction and get an old government or corporate machine that is only three years old for $50 and fix that up instead.
Wow, thanks for the ideas and knowledge sharing. My daughter is only 9 years old so she doesn't quite know that I am giving her a crappy pc...LOL. But I may see if I can find a newer one soon... for cheap.
