If you can’t find a specific reference to your problem, running through the following checklist stands a good chance of resolving the problem for you. This checklist is also usually the best approach to troubleshooting some specific Stop messages, such as 0x0A and 0x50.
1. Examine the “System” and “Application” logs in Event Viewer for other recent errors that might give further clues. To do this, launch EventVwr.msc from a Run box; or open “Administrative Tools” in the Control Panel then launch Event Viewer.
2. If you’ve recently added new hardware, remove it and retest.
3. Run hardware diagnostics supplied by the manufacturer.
4. Make sure device drivers and system BIOS are up-to-date. However, if you’ve installed new drivers just before the problem appeared, try rolling them back to the older ones.
5. Open the box and make sure all hardware is correctly installed, well seated, and solidly connected.
6. Confirm that all of your hardware is on the Hardware Compatibility List. If some of it isn’t, then pay particular attention to the non-HCL hardware in your troubleshooting.
7. Check for viruses.
8. Investigate recently added software.
9. Examine (and try disabling) BIOS memory options such as caching or shadowing.
