The words "none of the other stuff" is somewhat interesting; what do you mean by that?

Another rare but potentially possible case might be hardware fault which is harder to diagnose if you either don't have a storage medium that can be bootable from your computer and/or you're not comfortable with trying out another platform in order to trace down the problem.

Presuming it is it not a hardware fault but is really a software fault, there is no silver bullet that I know of which can pinpoint and solve your issue. For starters you might want to check your windows event log to see if there are any errors that maybe directed to your networking issues. Other technical areas which you may want to consider are (but not limited to):
 * Checking your computer to see if you have any spyware/malware running in the background. Even if you already am using a certain software that tells your computer is clean. Try at least one other software to make sure that your computer is really clean.
 * Run a software that can print a detailed node-by-node traces as well as delays such as |WinMTR.
 * Run packet analyser tool such as wireshark and see if somehow the packets were lost for some bizarre reason.

I strongly suggest for the first bullet point of other technical things to try is to assume your computer is infected and that you should try to look into software that would be terse in presenting reports. An old software that I used to use when dealing with spywares and what not is |HijackThis.

At any given rate, there will be lots of reading for you ahead for each and every one of the cases I mentioned here. Whilst you have another laptop that is working with the game - you may as well grin and bear with it until you get your current computer fixed. Otherwise, it would probably work out if you get a computer technician whom can physically see the issues you are facing, what softwares have you installed and what not and be able to work out a better solution.
