Your dump indicates that it was a driver fault. This can be caused by antivirus software, new drivers, and some software. it was not specific as to the issue but here is what I pulled out.
On Wed 2014-08-06 12:30:21 AM GMT your computer crashed
crash dump file: D:\Downloads\080514-17000-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x1500A0)
Bugcheck code: 0xA (0xFFFFD000428E5DB9, 0xD, 0x0, 0xFFFFF803F3957F2C)
Error: IRQL_NOT_LESS_OR_EQUAL
file path: C:\Windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
I suggest rolling back any drivers that have been updated or uninstalling new software. Do this one at a time so that you can identify the app/driver. With any luck you have only installed one new app and that is whats causing this.
