BSOD turned into "Black screen of death" -cannot boot into BIOS.

Dear everybody,

I have a Asus G73JW laptop with 2 x 500gb HDD, both has two partitions;
Win7 ultimate; 64 bit;
Nvidia geforce GTX460M, 1,5gb;
CPU: :Intel Core i7 - 740QM, 1,73 GHz; Ram = 8GB;
EAX advanced HD 5.0; THX trustudio
Security: AVG antivirus with windows firewall on at all times.
This laptop has not been the same since my wife, accidentally opened a zip file which was attached to an e-mail. I reinstalled windows [ must admit I did not format the windows partition, before installing it ]. I restarted after each and every installation of the different drivers. I got the 1st BSOD whilst installing Nvidia drivers. After this I started getting random BSOD on shut down and start up. I uninstalled the Nvidia driver and restarted the laptop and noticed that it installed an older driver for Nvidia. It was okay for a couple of days , but then I got a BSOD boot loop, I then did a MBR repair which seemed to work for a couple of weeks. This past weekend my wife and I was on sites advertising cars that are for sale and used google maps to get to the different dealers. The laptop's power cable disconnected by accident, battery went flat during the night and when I restarted it , it initially showed a BSOD, restarted and since then I get this black screen of death. The Asus logo does not even come up, the keyboard lights come on and you can hear the HDD running and later the DVD drive, but nothing else happens. I cannot get into the BIOS [ F2 is suppose to get you into it, but F2 does not work and neither do the F4, F8, F11,ESC or DEL keys. My BIOS is setup to boot from HDD 1st, then the DVD drive, at the moment. I cannot boot from my Asus system repair disc and neither from the Win 7 DVD or from the Minitool bootable cd ??

Is there anybody with any suggestions, I apologise for not being able to post the dump files or a more thorough list of system specs, but as you can see I have absolutely no access to the laptop.

Hi Dave, thank you for trying to help, I appreciate it. I am heeding your advice -- bought my wife her own laptop! I omitted to mention , but I did what you suggested before { got it off the forums }, did try again now, still with no luck. I am not sure whether this will help, but I made a copy of my device manager some time ago, will attach it, just in case it might help.

Hi Essenbe, thanks for responding, yes I got the drivers from the Asus site and yes this started with her opening a zip file attached to an e-mail. I then re-installed windows on the windows partition and then things proceeded as described in my original post.

Well, Essenbe thanks for intruding, I would love to wipe the drive clean [ or rather the partition windows is on ] and start anew, that is actually what I was trying to do, but as you can see from my first post I cannot boot from my windows dvd and neither from a Minitool bootable cd, I can literally not get into the laptop.
