I have recently experienced [PCIe Bus Error] which prevent the system from booting up properly.

The system is set-up to Dual-Boot: Win8 & Ubuntu

When running Dell HW diagnostic, no trouble was found.

When swap out dual Nvidia Titan2 GPU with generic AMD graphics card, the PCIe error was gone.

Contacted Dell Pro Support & they send Nvidia GPU replacements. Problem still persists.

Finally, Dell dispatch a tech to swap out the motherboard, problem corrected.... so far so good....

Just want to share this information.

Cheers!
