BSOD: IRQL Not Less or Equal

If you didn't run that particular test for 8 full passes, you haven't really tested your ram. Did you set your BIOS to optimized defaults and have you checked and made sure your computer is set to create small memory dumps? Dump Files - Configure Windows to Create on BSOD . Those things will help and could solve your problems. Until we get new dump files, there is nothing we have to go on to check. We need the memory dump files to debug the system. The computer will not create a memory dump until you get a real BSOD.

Try safe mode, if that does not work try last known good configuration, if that won't work, boot into the installation DVD and on about the 3rd screen, in the bottom left is an option to fix my computer. Try that to run start up repair.

On start up try tapping F8 as soon as you see the manufacturers logo and see if you can get the repair options/safe mode.

I'm not sure what you mean by all that doesn't work. you can't boot into café mode or recovery options, or you did those options and they didn't work.

When you built this computer, it appears you transferred the OS to the new system, you did not do a clean install, is that correct?

You apparently moved it from an AMD system to this Intel system, which may very well be much of the problem. Your files have AMD sata drivers in it, which do not get along well with Intel drivers.
