I checked using RAMMap on my PC that about 1.5 GB of my installed 4 GB RAM is driver-locked.
Most results from google searches tell me that this is usually caused by drivers of virtual machine management tools like VMWare, etc but that's not the case here since I don't have any such tools installed on my PC.
How can I pinpoint exactly which driver(s) is/are causing this and how can I make the memory available to other processes?
I was thinking that the locked memory would normally be freed up and taken by other processes when required but that's not happening and my browser (Firefox) freezes everytime the memory usage for it becomes >350 MB which is very low (just playing a song from youtube and opening up facebook makes the browser freeze after a few minutes). What can I do to solve this?

You have to use the Windows Assessment and Deployment Toolkit (ADK) to detect which driver uses "Driver locked".
The first step is to install the Windows Assessment and Deployment Toolkit and make sure you select the Windows Assessment Toolkit and Windows Performance Toolkit:
(The other components are not required).
After the tarce was captured you gave to look at the data.
Here you see something like this:
Now Expand the
Driver Non-Paged Allocations
category by clicking on the arrow on the left.Expand the

category:Here a genric graphic driver was the cause. Look which driver is it for your case. Look for the driver properties/version and loo kif you get an updated driver.
