HidClass.sys BugCheck

Experiencing a bugcheck resulting in a memory dump. What I'm seeing at the blue screen is hidclass.sys - Address FFFFF8800670AE0F base at FFFFF88006706000, Date Stamp 4a5bcbfd. I performed a sfc /SCANNOW. The result is "Windows Resource Protection did not find any integrity violations."

I am in the process of running Memtest86+. Thanks for helping.

Additional Info
My rig is overclocked @ 3.4GHz. Here is a partial list. I don't know if the info is needed.
Gigabyte GA-EP45-UD3P rev1.0 BIOS F10 (Mobo)

Just as general BSOD troubleshooting, I recommend resetting your overclock to defaults, at least until we get this all solved.

Update or uninstall these old drivers or their respective programs:

Code:

\ElbyCDFL.sys Thu Dec 14 16:22:27 2006- SlySoft CloneCD system driver file
pcouffin.sys Tue Dec 05 09:39:30 2006- Virtual CD drivers, probably related to SlySoft

The dmp points to your USB drivers as the cause.

Code:

BugCheck D1, {6714280, 2, 0, fffff8800670ae0f}

Probably caused by : HIDCLASS.SYS

STACK TEXT:

Code:

nt!KeBugCheckEx
 nt!KiBugCheckDispatch+0x69
 nt!KiPageFault+0x260
HIDCLASS!HidpInterruptReadComplete+0x30f
nt!IopfCompleteRequest+0x3a6
USBPORT!USBPORT_Core_iCompleteDoneTransfer+0xa15
USBPORT!USBPORT_Core_iIrpCsqCompleteDoneTransfer+0x3a7
USBPORT!USBPORT_Core_UsbIocDpc_Worker+0xf3
USBPORT!USBPORT_Xdpc_Worker+0x1d9
nt!KiRetireDpcList+0x1bc
nt!KiIdleLoop+0x5a

I would therefore recommend uninstalling your USB drivers, and installing a fresh copy.

Please upload any new dmps you might get.

No problem, glad I could point you in the right direction. If you need help with the memory timings, I know of a couple experts here that would be happy to help you.
