Re: New build, boot problems
Ok, here we go...
1. When building a new machine, always install the OS after the machine is built. Never install the OS on the hard drive then build around it. It will cause all sorts of problems. You might be able to boot into safe mode and uninstall every single driver for the system, then boot into normal mode and have the OS reinstall the drivers, but this is an extraordinary pain in the arse.
2. 32 bit OS and 8GB of RAM don't mix since a 32 bit OS is only capable of addressing up to 4GB of RAM.
3. If you're intent on installing XP on that machine, it will be easiest to slipstream the drivers in the install disk. nLite is a nice tool for this. Otherwise, if the installer can't find drivers for the HDD controller, you will need to press F6 to install the third party drivers, which in XP has to be from a floppy disk.
Ultimately, your solution would be performing a fresh install of a 64 bit OS.
