Scan for viruses with a full scan using the free version (do not start the trial) of Malwarebytes : Free anti-malware, anti-virus and spyware removal download and see the Good and Free system security combination. for better security steps and scanning tools.
Resolution
Resolving a bad block problem: An I/O status code of 0xC000009C or 0xC000016A
typically indicates that the data could not be read from the disk because of a bad
block (sector). If you can restart the computer after the error, Autochk runs
automatically and attempts to map the bad sector to prevent it from being used
anymore.
If Autochk does not scan the hard disk for errors, you can manually start the disk
scanner. Run Chkdsk /f /r on the system partition. You must restart the computer
before the disk scan begins. If you cannot start the computer because of the error,
use the Recovery Console and run Chkdsk /r.
Warning If your system partition is formatted with the FAT file system, the long file
names that the Windows operating system uses might be damaged if you use Scandisk
or another MS-DOS-based hard disk tool to verify the integrity of your hard disk from
MS-DOS. Always use the version of Chkdsk that matches your version of Windows.
Resolving a defective hardware problem: If the I/O status is C0000185 and the paging
file is on an SCSI disk, check the disk cabling and SCSI termination for problems.
Resolving a failing RAM problem: Run the hardware diagnostics that the system
manufacturer supplies, especially the memory scanner. For more information about
these procedures, see the owner's manual for your computer.
Check that all the adapter cards in the computer are properly seated. Use an ink
eraser or an electrical contact treatment, available at electronics supply stores, to
ensure adapter card contacts are clean.
Check the System Log in Event Viewer for additional error messages that might help
identify the device that is causing the error. You can also disable memory caching of
the BIOS to try to resolve this error.
Make sure that the latest Windows Service Pack is installed.
If the preceding steps do not resolve the error, take the system motherboard to a
repair facility for diagnostic testing. A crack, a scratched trace, or a defective
component on the motherboard can cause this error.
Resolving a virus infection: Check your computer for viruses by using any up-to-date,
commercial virus scanning software that examines the Master Boot Record of the hard
disk. All Windows file systems can be infected by viruses.
Sometimes, Memtest86+ will pass a few times and then fail. Memory testing is not an exact science, and since electronic errors can behave in a finicky manner, it is a good idea to run tests multiple times. Run the boot version of Memtest86+ again paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
If you swap any memory components, follow these steps for ESD safety:
- Shut down and turn off your computer.
- Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
- Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
- Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
Once these steps have been followed, it is safe to remove and replace components within your computer.
