Random Blue Screen re-boots

Over the last 6 months my computer has done a bluescreen/re-boot 3 or 4 times. When I check the event viewer I get the message: Fault Bucket X64_OxA_USBPORT!USBPORT!_Core_:CompleteDoneTransfer+45f,type 0 Event Name: Blue Screen Response: Not Available Log Name: Application, Source: Windows Error Reporting, Event ID: 1001 Task Category. None, Level: Information, User: N/A. When I go to Event log online help I get the message Product Version 6.1.7600.16385, Event ID: 1001, Locale ID: 2057, No results found for your query. When the system re-boots everything seems normal nothing seems to have been lost and the computer goes back to the page or application I was using before the incident occurred. I am running a 500gb 4gb RAM Pentium Dual Core E5200 @2.50ghz with Win 7 Ultimate 64 bit. As I said, the computer seems fine on re-boot and this has only happened about 3 or 4 times in the last six months (5/1/11 @00:13, 9/1/11 @14:09, 14/1/11 @3:42, 19/1/11 @17:39), and there doesn't seem to be any pattern to the timing of it. Can anyone shed any light on this, should I be worried about it. I don't like this Blue Screen thing !

 

No Yellow marks of any kind in device manager, the event viewer stated USBPORT! and the only things plugged in at the time were the printer and scanner (which were both turned off), the mouse, and an external hard drive which was on at the time, I thought it might be that.........................scratch that......it's just happened again while typing this and the external is not plugged in.........the computer has re-booted and Firefox has restarted and gone straight to the page where I left off when I was typing this post and the cursor and text that I typed was still there, and I just checked the event viewer and it says the same thing I already posted. This is strange, the computer seems to running ok and I have lost no data that I'm aware of so I'm not sure how serious this is ! I should also mention that an unexpected shutdown report window comes up on re-boot and I click on send report and the report is sent......as far as I know !

 

It’s just happened again……….and this came up

Can anyone shed any light on this ?

 

I also like to use a program called "who crashed me" which analizes BSOD dump files.

you can download it here

 

I used WhoCrashed and this is the report I got...

The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system which cannot be identified at this time.

A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: af15bda.sys (AF9015 BDA Driver , AfaTech ).
Google query: af15bda.sys AfaTech IRQL_NOT_LESS_OR_EQUAL

 

and

That says the probable cause and the driver that is causing it.

Do you have a USB TV stick?

 

Here's the company page http://www.afatech.com/EN/support.aspx
but I'm not having any luck finding an af9015 driver.

 

Don't have a USB TV Stick, but I do have KWorld Digital TV Tuner Software installed which I never use........could it be that ?

 

If I took a guess, I'd say yes. It won't hurt to remove the hardware and the associated program and driver.

 

Well, I've just uninstalled KWorld Digital TV Tuner software. Let's see if anything changes.........one thing though, when I restarted the computer a notification came up saying windows is searching for updates to DVB T 2, then installing device driver software, then AF9015 BDA device ready to use. How can that be if I've uninstalled it ?

 

Well, the uninstall might not have removed the updater. That is either running at startup or as a scheduled task.
What startup things do you see?

 

Not at start up or as a scheduled task........will have to wait to see if it happens again !

 

Well.......it just happened again...........I'm at a loss now !!!!
