Hi allot of the time when you have errors when trying to install windows and you get the blue screen it is caused by bad memory, if you have more that one stick of memory you could try to load windows with 1 stick of ram, if you get the errors with 1 stick try the other stick and see if you get errors then, also you could try taking everything  out except only what you need to install windows, hope this helps    Terry

You can check your system with either Dell Diagnostics or download a copy of Memtest86+ from here, burn it to a CD as a disk image and boot it.  It goes a good job of testing memory.  Let it run for an hour or so and if there are no errors, the memory is OK.
