Random BSOD with no dump files created, error 0x0000004A

Dear all,

I have been having BSODs few times today with the codes
0x0000004A (0x0000000007764DC2A,0.0000000000000002,0x000000000000000,0xFFFFF88016488B60)
IRQL_GT_ZERO-AT_SYSTEM_SERVICE

I have attached the zip file and a screenshot of the BSOD below.
It showed "Physical memory dump complete" however I could not find any dump files in the Minidump folder.
I managed to change the directory folder of the dump file location before another BSOD but still no luck.
I googled a bit on 0x0000004A but could get anything useful from it.

Can anyone help me on figuring out this problem?
I am having my finals tomorrow and I am really stressed out by this. I need my computer to be working fine.

Thanks a lot for your help!

With no logs there's nothing to analyse unfortunately. A 0x4A points towards a device driver but there's no way of telling what it is without the dump files, anything we could offer would be complete guesswork and that's not the way to go.

Check your settings are set as shown below and post up new logs if you receive any more BSODs.

1. Open Advanced System Settings
2. Click on Settings in Startup & Recovery
3. Make sure both boxes indicated below are checked
4. In the dropdown box ensure you're set to record Small Memory Dumps

Thank you for your reply, Boozad.
I have made sure that my settings were correct multiple times but still no luck. No dump files were created.
What could be the reason for this to happen?

Have a read through this.

There aren't any .dmp files in your attachment. These are required to analyse the BSODs.

Follow these steps:

1. Configure Windows to create minidumps:
Dump Files - Configure Windows to Create on BSOD

2. Set the paging file on C: to be the same size as the physically installed RAM:
Virtual Memory Paging File - Change

3. Set the Windows Error Reporting service to MANUAL:
Services - Start or Disable



4. Test to see that dump files are created:
- Open Windows Task Manager
- Navigate to the Processes tab
- Right-click on explorer.exe, and click Create Dump File



- Note the location of the saved file



- Check that location and confirm that explorer.dmp exists

Right.
Made a page file the same size of my ram on both min and max.
Changed Windows error reporting to manual.
And found the explorer dump file in the temporary folder in the User's AppData folder.
Now I guess I'll just need to wait and see if I get a dump file from my next BSOD?
Got a feeling that it won't take long...
Thanks again.
