|first it was the blue screen,now it`s DDLs for kernel.|
More info? Please explain what error you actually receive. What was the error message on the BSOD?
Had windows 7 on it but trying to put windows xp on it now
Do the above mentioned errors occur on Win 7? Do you have Windows XP CD? Are you trying to swap Win 7 with XP? Do you have any problems installing Win XP?
More info please.
PS. Depending what was the error code on the blue screen, maybe you should check your RAM for errors.
Google is your friend
Have a GREAT day!
