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
Try to get into BIOS consistently with just PSU/RAM/Mobo
Add CPU and repeat.
Add the hard-drive and try to get into the OS. If there are any failures, reformat drive + reinstall the OS and/or try another hard drive.
Add GPU and anything else ancillary one by one.
If at any step you get erratic/defective behavior - you found your faulty part.
