Track Following Error: serious hardware problem?

Hi, I have a Philips PCA460R (Yamaha 4416E) burner and since I have installed a new motherboard, i cannot burn cd’s anymore. I get a “track following error”. According to the help function in Nero, it can be a serious hardware error. They suggest to update the firmware, which I did, but the problem still exists. Can anyone help me?

Actually, I did install Windows ME on top of Windows 98 after I installed my new motherboard. DMA is disabled. Whatever I try, it doesn’t work.
