Windows 7: BSOD USBPORT.SYS Please Help

09 Jun 2013   #1

Windows 7 Premium Home 64 bit


I've been getting some BSODs before and after a clean (OEM) install of Windows 7 Home Pre3mium 64 Bit. I've run memtest (1 pass) on my RAM and it was fine. I'm working with an ASUS p5Q Pro board with an EN8400GS graphics card. I just added that card this week and had a crash after I installed (but I had them before as well). When the BSOD happened I was running 8MB of RAM, but I pulled it back to 4MB to see if that would avert another crash. I had hoped that installing the new version of Windows would help this, but it didn't. I've had crashes before and after the install.

I've attached my most recent crash dump files (1-4 with 1 being the most recent). Some crashes point to the USBPORT.SYS but others note a memory corruption.

I have the following using a USB port: a seagate goflex external drive; a wireless microsoft mouse and keyboard; a Cisco AE2500 wireless adaptor.

I don't recall doing anything specific for any of the BSOD crashes that trigger this.

Is this enough information? I'm sorry if I didn't include enough or have posted this in the wrong spot.

Any help would be appreciated.

BugCheck D1, {ffdca2a1, 2, 0, fffff88003f7185f}

*** WARNING: Unable to verify timestamp for win32k.sys
*** ERROR: Module load completed but symbols could not be loaded for win32k.sys
Probably caused by : memory_corruption
Usual causes:  Device driver
This bugcheck indicates that a kernel-mode driver has attempted to access a invalid memory address, and interrupt the current process, whilst the IRQL level was too high.

CHKIMG_EXTENSION: !chkimg -lo 50 -d !USBPORT

	[ 4a:48 ]
1 error : !USBPORT (fffff88003f71860)
There seems to either be a corrupted RAM module or the driver itself has become corrupted.Run Memtest86+ for least 9-10 passes, and preferably overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Test each RAM stick and every motherboard DIMM slot available.

But if you have got a result like that:
It is a motherboard issue. The particular slot is bad.
There's seems to be a issue with some of the USB drivers, follow these steps:
  1. Start
  2. Type: Device Manager
  3. Expand USB Controllers
  4. Uninstall driver (for every listed device)
  5. Reboot
The drivers should now be automatically reconfigured by Windows upon reboot.

If you are using any USB devices, then remove these from the USB ports (leave keyboard and mouse), and then update all the devices with the latest drivers, including the mouse and keyboard if applicable.

Turn off USB Suspension:
