BSOD after BIOS update, please help

Hi I have an emergency. I work independently so I don't have an IT support desk to turn to. My laptop is also not under warranty anymore and I don't have the option of going to a service center nearby.

Yesterday, I got a BSOD, and I don't remember the error message but I searched it online and someone said to remove the graphic driver and reinstall. Which I did. Intell 4000. So everything worked out and it seems ok but I noticed that Intel was the only graphic driver on the list so I checked my Nvidia 650M program and it would not open. I looked again at the drivers list and now Nvdiia was now back on the list but it had code 12 not enough free resources.

Again I looked up this problem and someone said that it was a persistent issue and that Dell had a new BIOS A16 or something I believe to fix this. So I downloaded and installed it. But now I get a new BSOD with the error "page_fault_in_nonpaged_area" which I'm having trouble understanding what I should do now. I feel like it was a mistake to install the new BIOS but I don't know what to do about it now.

I have a Dell Inspiron 7720
Intel Core i7-3630QM 2.4ghz
8GB ram
64 bit windows 7

I use this computer for work and need Skype to make business calls but I can't use Skype at all in Safe Mode. And anyway, I need to completely resolve this problem. I'm also know nothing about computers, hardware or software so I really get lost with a lot of the jargon I'm reading online and don't know what to do. Please help me.

PS I also tried to download an older version of BIOS A15, but in safe mode it won't let me run it even when i click run as administrator.

I'm in such a hard place I don't know what to do. Any assistance would be greatly appreciated. Please ask me questions if I haven't explained something well enough. Thank you very much in advance~

    after the bios update did you go back into the bios and hit factory default and then save and exit?? if the laptop bsod there a wrong setting in the bios. look under ram make sure xmp profile is turned on. if there setting for primany display set it to nvidia and turn off the onboard video. under sata ports see if it set to raid/ide/achi. windows will blue screen if you change the sata ports from achi to ide or ide to achi.
  2. I am flabbergasted. I don't know how or why but everything is working...or so it seems for now. After reading another website that said to go into BIOS settings and restore to the last good point. I tried it. I couldn't find anything like that. Basically I just browsed through the options in the BIOS menus. I exited and it started a boot once again....however this time, Windows stayed on. Usualy it will BSOD shortly after Windows opens, while the startup programs are loading...and it had done that consistently for a few hours.

    One thing I did do, was Dell has a feature F12 that does preboot system assessment test. It ran a million tests and I laid down to take a nap while it was testing. And maybe through all the testing it somehow cleaned out the problem?

    I just don't know. I don't understand. I'm so lost and confused but it is working. That's all I know.

    smorizio, thank you for responsding. I do appreciate the attention and care for my computer issue. So a big thank you to you.

    The takeaway lesson of this all: a computer is a tool, a treasure, and a very strange and vexing thing.
