After I upgraded my memory I startup the computer and got a error loading Operating System

Screen says
Verifying DMI pool data
Boot from CD
Error Loading OS

I can restart the computer hitting F10 select boot from hard drive and the computer loads ok.

I think the problem was caused when I installed 1gb of memory. I shut down the computer but I forgot to unplug the ac power cord.

Help

Hi there and welcome to PCHF, do you have a Windows XP CD?

Thanks for the quick reply

Yes I have the Windows XP Media Center Edition 2005 Operating System disc

Ok, whaqt i would like you to do, is go into your PC's BIOS (Tap F2 or Delete when the PC Boots) and make sure your CD Rom drive is set as the first boot device, if its not you need to make the required change. Insert your XP CD, save changes in the Bios and reboot the PC allowing it to boot from the XP CD. Then follow my guide to perform a repiar install: http://www.pchelpforum.com/tutorials...indows-xp.html

Thanks lot I'll try it now I'll get back to you later

Before doing a full fledged repair install you could also try simply re-writing the boot sector and Master Boot Record.

Simply boot from the XP disk and load into the recovery console. When you are at the "C:\Windows>" prompt, simply type "FIXBOOT C:" and when that's finished type FIXMBR and answer yes to any prompts. Reboot and give it a try. If that doesn't work, try putting the old RAM back in and see if that helps. If that works then you might have a defective stick.
