I have 98 machine. I want to change to XP. I attached a cd drive it is found by bios & also shown in my computer. No problem so far. the problem is as soon as i access the cd the computer restarts. I have tried to change the drive & cd also; so the problem is not with the drive. I also tried with first boot device as cd drive with same results as soon as cd is accessed the computer restarts. Any idea. Thanks all.
