I have a computer with Windows 7 Ultimate on it that I may need to reinstall. I set it up a few months ago and had problems which ended up being related to a bad IDE cable (yes, I know, old tech but I had some files I needed on there). I replaced the IDE cable and the install went through without a hitch. I then noticed that it seemed to be sluggish waking from sleep or hibernate. I finally got around to looking at the BIOS settings last night to see if that had a clue for me. Apparently I have my RAM set to a much lower than nominal speed, as well as many other settings that are funny and lower than they should be. However any time I change one of those settings Windows 7 hangs at boot up.
Does anyone have any idea why it might hang? Is it because Windows isn't detecting the new speeds correctly?
