That's relatively useless.
I don't see anything otherwise in your posts that even tells us whether your computer is a desktop computer, or a laptop or netbook computer.
Go here for how to find the Service tag "number":
Tell us what it is.
You can get the IRQL_NOT_LESS_OR_EQUAL error from many causes, hardware or software, but sometimes it can be just because the ram module contacts are not getting a good connection - this worked for me when I got that error:
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.
For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.
For a generic desktop computer, see the mboard manual if you need to - how to remove or replace the ram is usually in that.
You could also try loading Windows into Safe mode, or into Safe mode with networking (mode).
If you don't have the problem in those modes, some driver or software that is being loaded when you load Windows normally that is not being loaded in those modes is causing your problem.
(Remove any bootable CDs or DVDs in drives.
Press F8 repeatedly while booting, don't hold down the key, and when the black screen appears with "Advanced..." at the top of it, choose Safe mode, or Safe mode with networking..
Some computers have their own use for pressing F8 while booting. E.g. you may see a screen where you can select a device to boot the computer from. If you see something like that, READ the screen to find what key it is you need to press to exit that screen.
Press that key, then immediately repeatedly press F8 until you see the "Advanced..." menu. )
