Hi there. During 4 or 5 days I'm working with a PCU. It has an ABIT SG-72 MOTHER, all onboard, with 1 stick DDR 256, HDD Western Digital 40 GB, CD Writer and DVD reproducer. I installed the Windows XP SP 2 5 times!... but every time I restart the computer, it take a lot of time to pass all the tests. Once it passed, It stop for a long time in the messege: Verifying DMI Pool DAta...... , but the next step "updated success" never shows. No matter what, it allways ask for the System cause it cant find it. If I boot the computer with the xp bootable CD, it enters in the OS normally, I can work everything is working. But its a problem. I change the DDR between the banks but nothing happen., PLEASE... PLEASE... can you help me? Thank you a lot.
