And some we can't add a PCI USB 2.0 card so avoid these old machines.

Nothing's really busted here but the machine did get XP installed so random reboots is not unusual since the memory use changed from when the machine ran Windows 98. I offer no course on how to handle the old hardware but when it runs, it's nice.

HOWEVER THE CD is likely caused by "HOW DID YOU MAKE THAT CD?" issues. Many use the DRAG AND DROP method that created a CDRW that can't be read on most machines without helper software.

Next time, create a "single closed data session." Those words change from software title to title so massage it to your selected software.
