Continued from here

• Took it in last Tuesday, early this afternoon they called to let me know it was fixed
• New processor was bad, did not work with known good machines
• RAM was apparently loosely seated which was causing the lack of display. They said they were able to get it to POST (and installed the latest BIOS update)
• I took it home. It does not POST.
• I am taking the computer back tomorrow morning. If they can’t get it working in front of me, I am giving up and buying a prebuilt PC online
