1) Providing information about the stop message (write down the stop code and parameters when it appears) can help diagnose your specific problem. (You need write it down if you can't boot to get to the Event Viewer)
2) Your CD install disks can help you fix filesystem and Windows corruption on your HD which might be causing the failure
3) But i'd also be concerned about HD failures/reheating/etc. Did you run backups before it failed? As you might want to first focus on your file recovery from HD and THEN address Windows sytem corruption
4) See
this thread about options for file recovery. Also note the thread ends with full and successful! method for the user to recover their files even when hindered by not having their install or bootable CDs on hand
>> As if you don't have CDs you can download boot CDs to help as well
>> Or remove the HD to put it in an external enclosure and try to fix it on a friend's computer
>> IMHO If you try the external enclosure approach be sure to buy
one with an AC adapter
As to fixing your HD/getting its files
>> I'd normally recommend first run
chkdsk. But it can take a looong time to run. I'd be concerned about the HD reheating/failing again before it can complete
>> So you might be best to just first try booting from the Knoppix CD and try to save all your files/folders first
>> If Knoppix reports file corruption you'll have to run chkdsk first to try and fix it before Knoppix can read it
>> Also if your HD is failing and you can't read it, note the
"freezer" trick others have said has helped get it working long enough for file recovery
