im getting an error message, and wanted to see if i could start up using the cd….i did, and it worked….now i need to enter, repair or quit……which do i do so that it only starts up and does NOT reinstall the system software? I dont want to lose anything…i only want to see if i can fix this before reinstalling windows………thx

see earlier questions if ithis isnt enough info

After installing new updates I restarted my computer and I got a msg saying windows failed to start a recent hardware of software change might be the cause and it told me to put in my Windows Vista disc and "repair my computer" so I did. Then I got an error msg saying "The instruction at 0x73c7060 referenced memory at 0x000000000. THe memory could not be read" So now my computer doesn’t do a thing. THis is the second problem I have had with windows in the past three days. Do I need to buy a new computer?! What is the problem?! Any ideas!? I also tried reinstalling windows vista but it just said "To use the product Key you have entered, start the instalation from your existing version of windows" which I can’t do because WINDOWS FAILED TO START!

Thanks for any help anyone can give me
