BSOD followed by a lost of 12gb HDD space

Question

Hello,
I've encountered BSOD saying "IRQL_NOT_LESS_OR_EQUAL". Soon after restarting, I've noticed that I have a lost of 12GB hdd space. 
This is not the first time. Last week I have another BSOD, which was related to my nvidia driver, and soon after restarting I had a lost of 10GB hdd space.
I did some research online and someone suggested that it might be due to the size of the dump file. I've check the dump file and it is only a mere 292KB! 
Could anyone please let me know how to recover the 12GB lost of hdd space as well as solving the "IRQL_NOT_LESS_OR_EQUAL" problem?

Texts in bold are the event log which I've copied out. There are 15 of event ID 24 and 1 event ID 10. Sorry if it's too messy. 
Please let me know if you need my dump file or any other details.
Any kind of help would be much appreciated. Thanks.

Answer 1

These crashes were related to memory corruption (probably caused by a driver). 
Please run these tests to verify your memory and find which driver is causing the problem.  
If you are overclocking (pushing the components beyond their design) you should revert to default at least until the crashing is solved.
If you don't know what it is you probably are not overclocking.
1-Memtest. (You can read more about running memtesthere)
2-Driver verifier (for complete directions see our wiki here)
ALSO...
Please provide us with your Event Viewer administrative logs by following these steps:
Click Start Menu
Type eventvwr into Search programs and files (do not hit enter)
Right click eventvwr.exe and click Run as administrator
Expand Custom Views
Click Administrative Events
Right click Administrative Events
Save all Events in Custom View As...
Save them in a folder where you will remember which folder and save as Errors.evtx
Go to where you saved Errors.evtx
Right click Errors.evtx -> send to -> compressed (zipped) folder
Upload the .zip file to skydrive or a file sharing service and put a link to it in your next post
If you have updated to win 8.1 and you get the error message "the system cannot find the file specified" it is a known problem.
 The work around is to edit the registry.  If you are not comfortable doing this DONT.  If you are, backup the key before you do
Press Win+"R" and input regedit
Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels. Delete "Microsoft-Windows-DxpTaskRingtone/Analytic"
