My uncle wants his old pc to get fixed. He is having some issue related to slow system. There is a CD rom in the computer. I added by CDRW to it. The reason was that the old CDROM does not work properly. I want to format the computer and when I boot from the CD the entire system freezes. I can see the drive listed in Device Manager. But there is a driver failure error. The same is happening to the other CDRW also. I am not able to figure out why this is happening. I had restarted my system a couple of time but still the issue occur. Both are IDE drives. I hope there would be some way to deal with the issue. Thanks.
