I recently discovered that the RAM I installed in my computer was set by the manufacturer to 2-3-3-6 timing instead of 3-3-3-8 timing which was what my BIOS had it set to, so I went and changed the values to 2-3-3-6. I restarted my computer but it wouldn't start. It started loading, did two beep like normal, but then just stopped at a black screen. So I went back and set the timings back to 3-3-3-8 but the same thing happens when I try to start it. I ran memtest86+ a couple times to make sure the RAM is still fine and the tests complete with no errors. I can hit F8 and access the menu to boot in safe mode, last good configuration, etc., but none of them do anything other than bring me to a black screen. How can I fix it? The microsoft site tells me to just do a repair installation of Windows XP but I think there must be a simpler way. Thanks for the help.
