What does bad UltraDMA Controller mean?

Specs: Windows 7
I have an old Aser computer that I love. Recently it has been going Blue Screen and restarting quite often. One day I turned it on and got an error message that stated :Bad UltraDMA Controller - QDMA not loaded. Can anyone enlighten me on what this mean? I contacted Office Depot to see if it could be repaired and was advised to throw it away and not even attempt to repair it. They couldn't give me an explanation for this problem but started their speal about the computers that they have on sale. Can this problem be repaired or are they just trying to sell me a new computer? Any advice would be greatly appreciated.

The ultra DMA controller is usually part of the Southbridge chipset on the motherboard & interfaces with IDE devices (hard drives, optical drives) among other things. If it's defective, the entire motherboard will have to be replaced. What is the model/model number of your Acer?

Make sure every UltraDMA hard-disk was made "active" through the BIOS. ( Not SATA or IDE mode )

Also, make sure you are in DMA ( Not PIO mode )
