Windows 7 - BSOD (IRQL Not less or Equal) - downloading

[SeanZJ]

Hello, I was just recently downloading a VPN client, and I started getting the BSOD error. First it occurred as soon as soon as I started my computer back up. Then I didn't get it until I opened up Firefox. Now I managed to uninstall the client I downloaded, and it hasn't persisted, but I am wary that it will come back. Is there anything that I can do to see exactly what happened and what will make the issue return?

Can you post the crash dumps following the Blue Screen of Death (BSOD) Posting Instructions?

If we can see the dumps, we can try to answer exactly what happened there, and what might make the issue return.
