I suspect you might have a memory problem but there might be other things wrong. See if you can boot into Windows Safe Mode by pressing F8 as soon as the system powers on. If you can get into Windows try running the memory diagnostic tool by searching for it in the search field of the start menu.
If you can't load Windows try booting from the Windows CD and do a repair install. The repair install overwrites the current Windows install with a fresh install but keeps all your data files. If that fixes things up again try running the memory diagnostic tool.
Thanks for you reply, Brad, and pls excuse me for my lack of clarity.
I can boot into win7 desktop no problem, I can also install other m/b drivers manually by downloading them from the Intel website , but for some reason, when I attempt to install the Chipset Driver (which the disk installation requires before I can download the other required drivers), the PC won't automatically reboot when the installation requires it to. It just freezes and a shuts down (after about 10mins), restarts OK, but the installation fails.
I have run this Chipset Installation disk before when my old Hard Dives were working, and I had no problems, it installed fine. The issues began when the Hard Drives were replaced.
I hope that makes more sense.
