I had a problem with my computer so I took it to the shop. The motherboard was found to be defective. The store replaced the motherboard. The tech person told me that I would have to "Repair" my Windows operating system before my machine would work. He said to just install my Windows CD and select the "Repair" option. He said that it would basically reconfigure my operating system to work with my new motherboard. So I get my machine home and I make the CD-rom drive my bootable drive. I insert my Windows XP Professional CD into the rom drive and start up my machine. I see the message "Boot from CD" displayed and then another screen pops up right away. The screen gives me options to either "Start from safe mode and other safe mode options", "Start Normally", "Start from last known good configuration". But no matter what I select I get the blue screen of doom. I remember doing the same thing with my friend's computer but her hard drive was empty and the Boot sequence would actually give me the message "Press any key to boot from CD"......which is what I want. I checked all BIOS settings and I can't see why my boot-up CD is not being run properly. No matter what I've tried I keep getting the option screen described above which always leads me to the blue screen. There was only one time I got a different message on startup. It was the message "Re-install from Windows XP Professional or something similar to that". I got that message because I was hitting the F8 key on starting the machine. But when I selected the option to "Re-install from Windows XP Professional" I immediately got the above screen described above with all the regular start-up options. Can someone please help me out and tell me why I'm not getting the Windows install CD to run properly and how I can get it to run. Thanks in advance for all your help.
