my windows corrupted after clean copy of win xp pro sp2 why ? May be cd corrupt i tried another cd but again corrupt i also creat new partiton but again please help me ? Thank you very much.

I want to repartition & reformat harddisk and make a clean installation of ‘XP pro sp2’

I have just reformatted my windows and installed and now it is run on win xp sp2. But my computer would crash/freeze completely all of a sudden like once every hour or so. I also have antivirus program BitDefender 2008 installed and have just ran its registry scan/cleaner. I’m now trying hard to find out the cause and to fix this. I was thinking, could the registry scan/cleaner have messed up the win xp’s registry and thus causing these crashes? Also I’ve noticed every time I shutdown/logoff windows, “spool.exe” would have trouble closing and I would always have to force it to “end now”.

"Windows could not start because the following file is missing or corrupt:
<Windows root>\system32\hal.dll.
Please re-install a copy of the above file."

This is a common error and I see all kinds of troubleshooting online. This message has come on my computer many times. The error has probably happened at least 5 times and I had to reformat my hard drive each time. None of the online solutions helped besides reformatting. I maintain my computer with recent updates and Norton. I also noticed that when I install some LEGIT programs, my computer tends bring this error.

My computer is around 8 years old that uses XP SP2 but I can’t afford a new one. Is there a way to prevent this hal.dll error? Should I buy a new hard drive? I replaced my original hard drive around maybe 4 years ago with a Seagate Barracuda (currently using). One weird thing to note is that the hard drive has worked when under a hard drive enclosure. Not sure about now. Any suggestions?

I upgrade from SP2 to SP3 and it is low on memory before the upgrade.
