If all failed, check Device manager, see if you enabled DMA for CD drive, sometime you need to disable this DMA option if you experienced problem.

I have an Acer CD-650P and a Samsung DVD SD-606F in my Pent 3, 450MHZ home built computer. For about a year now, I have been unable to load Office 2K Premium on this computer, and I keep getting the same 2351 and 2355 errors when I try to install. I have been in touch with the braintrust at Microsoft, and they suggest slowing down the CD-Rom, and this doesn't work. I have tried everything except replacing the CD-Rom drive, but I'm about ready to do that. I have an Asus P3V4X mobo, 128MB RAM, and short patience. Any suggestions?
