AT WITS END=PLEASE HELP! Unable to restore; No password; Bluish green-blac​k flickering monitor

Question

Hi all, first time here, and I regret this is so long, but PLEASE bear with me.  Having gotten nowhere after roughly 20 hours of labor plus 8 hours with "customer support", I REALLY NEED YOUR  HELP!, PLEASE.. I have a Pavillion dv7-4087cl entertainment notebook running Windows 7, Home Premium, 64 bit, Product # wq637ua#aba. In essence, the primary issue is that I'm unable to do anything on my notebook. which includes a Notebook Recovery - the problems are broken down below.
Problems:
1. I noticed that the screen began to flicker, rapidly alternating between blue/green and black.  This seemed to coincide with an update that I was instructed to install on 7/19 by rebooting my computer (it was either an HP or Microsoft update). Of note is that there is no flicker when I am in Recovery Manager, Advanced System Diagnostics, or other "fix it" screens.
2. Also, another  major problem that keeps showing up is that this machine uses finger swipe technology to log on. I was so taken with the ease of this when I first got the machine < 8 months ago that, to my recollection, I never entered/registered a password.  Everything went swimmingly... until now.  However, now that I have this problem, I am unable to proceed with several possible remedies because it asks for the unrecorded password.
3.  Given the aforementioned, I've been unable to do a Notebook Recovery.
REMEDIES ATTEMPTED: 
1.  I have run Start-Up Repair with everything being ok, in HP Advanced System Diagnostics I ran the Tune-Up Program and all was well, and the same applies to the Hard Disk Test.  As per response to ADG's 7/12/11 post, I followed the directions found there, as follows: 1. insert CD and boot into recovey manager, 2. "Windows is loading files" message displayed, with "Welcome to Recovery Manager' at the top 3. However, I did not see Advanced System Options or System Recovery, but was able to access those somehow during another attempt at a fix 4 Was unable to find "Recover without backing up" or to click on "System Recovery" which was listed but, as noted below, it was not an option I could access/click on.  Although the screen said something like "reloading files", as I had my recovery DVD inserted, when that process was done, and the system rebooted, it was back to the blue/green/black rapid flicker. Along that line,  I made my  own Rescue Disc, and it is only one DVD.  In reading others' posts, sounds like I should have at least three discs. Do you think I need to order these from HP?
2.  Performed a "Hard Reset" to no avail.
3.  I have tried every approach that I could think of (e.g., F8, F11, System Recovery,  Advanced Diagnostics, etc.), and that the lack of a password would allow.  One thing I noted was that only two restore points were listed.  One was dated 7/18/11, it was an automatic resore point, and the "type" was "System".  The other was dated 7/19, which is when the problem first manifested, and it said it was an "HTFS" or some similar acronyms, and the type was "install".  It was after this install that I noticed the problem.
4.  Customer support rep said to do the following:  Run Hard Disk Test and, if it passes we know it's not a hardware problem - it did pass.  After the test,  he said to choose "shut down", but the closest option was "Exit", which I did  He told me to turn it off and, while rebooting, press F11 which would yield three columns.  All was going well at that point.  He said that beneath the "I need help immediately" screen, to select "System Recovery".  However, while that was listed, the only option to which I had access was to "Microsoft System Restore".  I clicked that, as I had done Many times before and, this time, as with the other times, it was just another exercise in futility.
STATUS:  The machine is not even 8 months old and, despite all efforts, it remains broken.  I am unable to do a recovery/restore, It appears to be a software problem, and I have no password which prevents many solution attempts, as well as other likely problems down the road. My finger swipe was all that I ever needed up to this point - lesson learned.   Thank you so very much in advance, sorry this is so long, and I would Greatly appreciate your H E L P

Hi,
First of all, try the following to see if this will allow you to boot into Windows.
Download the application on the following link and save it to your Desktop.
PC LoginNow
Next, download and install  ImgBurn.
Now, download and install 7-Zip.  When installed, right click the PC LoginNow download, select 7-Zip, select Extract Files and click OK.  Open the newly extracted folder and use ImgBurn to correctly burn the ISO file to a CD.  A guide on how to use this is on the link below.
PC LoginNow Guide
Insert the CD into your PC you can't log in to and restart to boot from the disc.
Hopefully this should simply remove your password altogether.  Let me know the result of this before going any further.
