My Laptop is a Dell, but since you haven't had any luck. I had a similar problem. It was the driver on my touchscreen that kept 'thinking', (must be cortana tracking my every move), I was touching it. I finally disable the touch screen and the problem went away.
Jack of all trades, master of none, though often times better than master of one.
I had a reasonable horsepower Vista machine which I decided to do a fresh install to Win10 on a new SSD. Part of that involved reloading the display driver from Dell. Everything worked fine, until when some unknown update from 1607 in the direction of 1709, the machine bricked. When booting, I would see a message that Windows didn't like something, wants to revert to the previous version, then it reboots and repeats the process.
I didn't actually like the Windows 10 fresh install solution since I had about 100 software products and pre-configured thingies that were useful to me. I decided to upgrade the Vista system to Windows 7 to Windows 10, then moved the resulting partition to the SSD. I reloaded the display driver. Everything worked fine ... until some unknown update.
Long story short, I now have no end of problems with drivers. Right now I am at the state where the desktop gains focus about every 59-72 seconds, the desktop goes black for about a second, any instance of Explorer, control panel or file open dlg closes and my current app of interest loses focus (including browser, word etc.). The desktop comes back, and start menu (hidden for me) comes alive and focus goes to the desktop. Various pages found by Google say that it is a wary driver that is at fault (or a short list of several known problematic apps). Most drivers have to do with either sound or display driver. I've spent about 4 man days on this in the last couple of weeks. Not solved yet.
I've not been in a complementary mood towards Microsoft for the last month.
I have to login to a government site and I can set up password recovery.
They need my email and a secret question and answer.
I get to pick from four pre-defined questions, but they are so difficult that even I can't answer them!
The easiest is the expiration date of my drivers license, but that will change once it expires and of course I won't remember what it was when I get my next drivers license.
Another one is my client number of my electricity company, that only changes every year when I switch company...
The answers to the questions are so hard I am literally forced to write them down somewhere (and keep copies and backups).
Great job government, this will make everything so much more secure!
I'll just not set up password recovery and hope I'll remember this password to a service I need once or twice a year...
It's just like the change your password every 30 days policy I have at work.
It means that everyone picks a password then simply increments a number at the end of every 30 days.
This means that if anyone cracks your password without you realising - they can hack your account well into the future.
Security measures should be there to slow down unauthorised access and as you have pointed out some modern security practises have actually decreased security.
“That which can be asserted without evidence, can be dismissed without evidence.”
For that reason we have the policy that your new password must be at least x% different from your old password...
But I've seen the increment as well.
In one such scenario I've even seen that an entire team got one account to access some server.
Every month the person who changed the password would send out an email saying "the new password increment is now 19" (this was important, because after 3 failed attempts you'd be blocked and in for a world of pain trying to get it back).
Speaking of Windows, to change the password you have to provide the current, as well as the new password. I suspect the comparison is done at this stage, because storing non-hashed passwords (at least in AD) supposes to settle a special policy, which fortunately is not applied by default.

I once created a really long password using all the allowable characters. When it came time to change it, the new password was rejected because it had too many of the same characters as the previous one. If the sysadmin had not been able to override that rule, I'd never have been able to use that system again.
A study was done a number of years ago regarding password complexity. The finding was that as complexity increases, security is reduced - because people have to write their passwords down in order to remember them, thus completely defeating the security that the demanded complexity affords.
I got you beat though - along with the complexity requirements (at least 16 characters, no more than three consecutive letters or numbers, must include numbers, a mix up upper and lower case letters and special characters, no group of letter can create a word, and every time you change it, it can't be more than 50% similar to one of the last 10 passwords you used), my employer forces a password change every 15 days.
This is done for our time sheet app. I mean seriously - WTF!? My strategy is to simply create a GUID in Visual Studio and submit it until one passes their absurd validation, and then save it in a text file.
