I have a Dell XPS desktop running Win7 64bit. It is about 2 years old. The computer first showed irregular freezing problems. Then eventually it stops working. When I press power button to turn it on, I get a message
Primary Master Drive – ATAPI Incompatible
Press F2 to Resume
If I press F2, it enters BIOS. After quitting BIOS, I get the following message:
SATA 1: Installed
SATA 2: Installed
SATA 3: None
SATA 4: None
This message repeats if I keep pressing Enter key. I wonder what will be the problem of the computer. I bought a brand new hard drive to replace the existing hard drive, and the same problem is still there. That means the existing hard drive is ok. What else could go wrong then? Could it be memory, motherboard, or DVD drive problem? I noticed that the DVD drive cannot burn disks properly when the computer works. But will it cause such a problem? Any help is appreciated.
