First off I hope this is the right thread for this question. I've searched for this problem and found some help, but not one that will work. First off I'm rebuilding a simple system for my daugther so the hardware and software are older. The computer is a pentiem 4 system with a 40gb hard drive and 512 ram. Here is the problem. I'm trying to install windows xp home edition to the system, the cd boots up and everything seems to be work all right. The files load and it states that setup is starting windows. Ok so far so good..however it doesn't do anything...20 mins go by and still nothing. So I decided to restart the computer and they a blue screen is there telling me that windows has shut down( did it really ever start) to protect my computer and files it then states DRIVER_IRQL_NOT_LESS_OR_EQUAL Now I looked into ways to fix this, but they all state going into window safe mode, since windows never started or was as far as I can tell never fully loaded that won't work. So my question is how can I tackle this problem if I can't get into safe mode since windows was in the process of loading not on the system..Thanks for any help you can give, if more info. is needed just ask and I'll answer them for you. Thanks.
