i am trying to fix a friends amd k62-500 64 mb of ram and a mobo that has everything built in usin the sis 530 chipset. here is the problem. she was using the computer just fine then one day it quit booting up. it would count the ram then itwould give her an error. i took and i tried starting it up with a win98 startup disk and it gets the point where it asks about starting with cdrom support. then it looks like it starts loading drivers, it says something about pci bus scan then just freezes. i put in a win2000 cdrom to try and start it from there and still it freezes. could it be the hard drive or mobo..i did replace the cmos battery thinking that was the problem. sorry for the long post but i am getting frustrated. btw she has a 10gig wd harddrive.thankyou in advance....
