Hey there shineboy and welcome to the forums,
Take a look at this information which is posted on the microsoft site:
If you have installed any third-party software or drivers, try removing them or disabling them so that they do not load, and then restart the computer to see whether that software or driver is causing the error. If that software or driver is causing the error, report the problem to the vendor of the software or driver.
Examine newly installed hardware
If you added any hardware device after Windows was installed, remove the newly added device to see whether the Stop 0x0A error stops occurring. If removing the newly added device resolves the problem, use any one or more of the following methods: ?Obtain updated drivers for the device if they are available.?Call the vendor of the device to see whether there are any known issues with the device. ?Run diagnostics to make sure that the device is working correctly. ?Examine the logs in the event viewer to determine if there is any event information that can help you determine what device or driver is causing the problem.

So basically if you have installed any new hardware recently then try removing it, alternatively it may be an issue with your windows installation which we can look into after you have tried what microsoft suggest above.
