I have a feeling AVAST! is causing your troubles.
It's been known to go a bit loopy on some machines with win 7.
You may remove it and use Microsoft Security Essentials for the time being.
http://www.microsoft.com/security_essentials/
Debugger data follows.
Code:
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: 00000016, 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: 82e5ba5b, address which referenced memory
