If your computer started misbehaving after you have installed new programs or games, it is possible that one of them is creating a conflict in your computer with one of the drivers.
Also, if you are a Windows user and see one of these stop codes: STOP 0x0000007E (SYSTEM_THREAD_EXEPTION_NOT_HANDLED), STOP 0x0000008E (KERNEL_MODE_EXCEPTION_NOT_HANDLED) or STOP 0x00000050 (PAGE_FAULT_IN_NON_PAGED_AREA), that may be another sign of a program-related conflict.
When your computer crashes and you see one of the following stop codes: STOP 0x0000007E (SYSTEM_THREAD_EXEPTION_NOT_HANDLED), STOP 0x0000008E (KERNEL_MODE_EXCEPTION_NOT_HANDLED) or STOP 0x000000EA (THREAD_STUCK_IN_DEVICE_DRIVER), a program running in the Kernel encountered an unexpected condition it could not recover from. They have identical troubleshooting and resolution steps.
Updating the BIOS to the latest available revision will solve the problem.
Check your BIOS version (Start menu -> type System information in the search programs and files box).
Go to the motherboard manufacturer's website and search for and download the latest BIOS update
DO NOT DOWNLOAD BIOSfrom other websites, because it may be corrupted, and if you install it, you may have to replace the BIOS chip on the motherboard to repair your computer
Run the BIOS updater (in Windows) you downloaded from the manufacturer's website and click on Update/Flash/Run (or something similar) button.
Once you've done that, all that you have to do is relax and watch your BIOS getting updated.
Note: Updating the BIOS is not a very complex process which requires your full attention and care. Also, a power failure during the update process can corrupt the BIOS and make your computer unusable, until you have the BIOS chip replaced.
If you use a laptop, connect it to the AC adapter.
