CPU, Ram, Video, Drive, MB ... the installer doesn't like one or the combination of them.
Since pc's are fairly generic these days, bios issues, ram, and cpu are common. With CPU issues you might expect the "unexpected" and I would suspect it to do something other than "freeze" every time. Plus you should have seen something with XP.
Bios options and updates would be first suspect, try loading the defaults, try loading the "safe" settings if it has them. Get updates if available, look on line using the common motherboard part number for any issues with windows server (ie. re-search the net/google/s.engine, using the motherboard name/model with "lockup freeze windows server" or some such)
Ram and Video could easily be culprits and during boot the cd's do try to load drivers, so that could be the issue there, or perhaps specific chipset drivers. If you have the option to swap parts, start with video, then ram, half ram, etc.
If that fails, you're back to motherboard and CPU themselves ... sometimes there are compatibility issues. Slowing down ram, combined with not enabling SmartHDD options and disabling all ACPI functions (some ACPI functions are not labeled so just "disable" acpi doesn't diable all of it)
Pick a path, change one thing at a time.. lather rinse repeat..
