Update your AMD Display driver, the current version is obsolete
AMD Graphics Drivers & Software

Remove AVG Antivirus/Internet security and use MSE

Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads
You can use MagicDisc as an alternative.

Remove TunUP Utilities since it could have messed up your system
Windows 7 does not need any 'TuneUp' software or whatsoever related utilities
Run SFC /SCANNOW Command - System File Checker

Broadcom iLine10™ PCI Network Adapter - Download & Install the latest version from your manufacturer's website.

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: ffffffe0, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: 832a8394, address which referenced memory
