Crashing when closing tabs/windows

I have a Toshiba Satellite running Windows 7. I spend a lot of time on Face Book and am having trouble with random crashes.

As I read messages, I open ones I want to read in a new tab. Once I get a few collected I will open one to read. The problem occurs when I close that tab or go another tab. I usually get a blue screen with the crash info and memory dump, the it will reboot back to the main screen where all my shortcuts are listed. I have to go back to sign in if I want to read anything I had in the tabs. Occasionally, I get the black screen asking me if I want to run in Safe Mode.
This is just plain annoying. It may go for long periods of time without crashing, then do it so much I get frustrated and just shut down.
Is there anything I can do to fix this problem? I've run Malware Bytes, Reimage scan and repair, and C cleaner with no luck.

 

The first crash message is a blue screen with Driver_IRQL_not_less_or_equal
and instructions using safe mode.
When the crash dump counter reaches 100, it sometimes goes to a Windows Error Recovery screen with choices about starting normally or in safe mode.
I use Whitehat Aviator and Firefox browsers.

The crashes are random, but always happen when I am changing tabs. It may allow me to change or close several in a row then suddenly "crash".

 

Hi my friend , welcome to MG's :major
You can follow this process pointing out what is the exact bsod's message

at the bottom of the laptop there is a sticker with the model number , you can inform about that

in many cases the ram is the cause of this problem :wave

 

BlueScreenView is a useful app that gathers up and translates all of the pertinent info related to your BSOD crashes.

If you could copy and paste some of that info here, it would really help. Or you could save it all to a text file and attach it to your next post. Here are some instructions on how to attach a file to your post:
