BSOD - Driver IRQL not LESS or EQUAL on laptop

Hi

So I have a Acer laptop and I had it like a year already and no BSOD's or errors everything was fine before the BSOD's started randomly poping up.So it got so frequent that I reinstalled win7 Ultimate 32 and it was fine for month or two and then again

BSOD - Driver IRQL not LESS or EQUAL

I study IT and I'm quite sure that isn't my laptop's hardware fault and as I saw in the perfmon/report there was some errors in
Hardware Device and Driver Checks/PlugAndPlay Device Configured Fail Count section so it must be some portable/USB device but I can't be sure.
I also attached todays .dmp files and perfmon/report .html file
Thanking in advance.

Please remove any CD virtualization programs such as Daemon Tools, Alcohol 120% or PowerISO. 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.


Code:
sptd.sys        0x8b081000    0x8b174000    0x000f3000    0x4ad245ea    12/10/2009 00:54:02
A driver from Atheros Communications, Inc is the cause
It is a Lan/Networking driver, upodate it from your computer manufacturer's websiute

Code:
BugCheck D1, {0, 2, 8, 0}

Unable to load image \SystemRoot\system32\DRIVERS\athr.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for athr.sys
*** ERROR: Module load completed but symbols could not be loaded for athr.sys
Probably caused by : athr.sys ( athr+7b223 )
